Cora Blu "A Little Underwater Did You Know"

Although tiger sharks are native to the tropical waters of Pacific Ocean, in my world they live in all waters. As the largest member of the carcharhinidae family of sharks, which include other species like the bull shark (head of security in “Dagger”) and blue shark, they are majestic in my opinion.

One of the interesting facts concerning the tiger shark is their propensity to venture into shallow waters in search of prey—a behavior not common in fish of this size. (10-14 ft in length)

Tiger sharks are fish, not mammals, hence the gills. 

Reproduction: Female tiger sharks become fertile about every three years, they carry 80-100 fertilized eggs. Only one or two of these eggs survive, resulting in a live birth about 14 months later. 

(Fortunately, I’ve tweaked that a touch in “Dagger”. To be pregnant for fourteen months is a bad look, doesn’t matter how much pregnancy glow you have.)

What happens if you turn a shark on its back—if you get that close? Tonic immobility.

This is a behavior, which occurs in sharks when a diver turns them onto their backs in the water. For some reason, turning a shark onto its back causes the shark to go into an almost trance like state. As soon as a shark is turned right-side-up again it swims away acting as if nothing had happened. Scientist have not yet discovered what causes tonic immobility in sharks, but they have theorized that being turned over somehow causes an imbalance which puts the shark into this immobilized state.

(In California a pod of killer whales have somehow figured this out. By ramming the shark in the side, flipping it over, it’s immobilized long enough for the killer whale to then hold it suspended upside down until the shark slowly suffocates and dies. Seemingly they only eat the sharks liver.) 

  • Hearing:
    1. Sharks have only an inner ear, which consists of three chambers and an ear stone called an otolith. A shark’s inner ear detects sound, acceleration, and gravity.
    2. Sharks use sound to locate food.
      1. Sound is often the first sense a shark relies on to detect prey.
      2. Under water, sound travels faster and farther than on land.

Sharks are attracted to low frequency pulsed sounds, similar to those wounded or ill prey would emit. Most attractive sounds are in the frequency of 25 to 100 Hz. Some sharks are attracted to sound sources from distances as great as 820 feet.

(These proved helpful in creating my characters, pretty cool when you can feel someone at the front door when you are in the shower)

  • Lateral Lines:
    1. The lateral line system is a series of mucus-filled canals just below the skin of the head and along the sides of the body. The canal is open to the surrounding water through tiny pores.
    2. Like the ear, the lateral line senses low-frequency vibrations. It functions mainly in distance perception and detecting low-frequency vibrations and directional water flow. Water movement created by turbulence, currents, or vibrations displaces the canal mucus. The lateral lines in the shark transforms underwater sound or mechanical disturbance into nerve impulses.

Eyesight

  1. Sharks have good eyesight and they have color vision.
  2. Shark eyes have a large, spherical lens, a cornea, a retina, an iris, and a pupil. They even have good vision in dim light.
  3. Sharks, like cats who also see well in dim light, have a mirror-like layer in the back of the eye, the tapetum lucidum. This layer doubles the intensity of incoming light, enhancing light sensitivity.
  4. Unlike other fish, shark’s pupils can dilate and contract to control the amount of incoming light. The retina has a greater proportion of light intensity sensors (rods), than color sensors (cones), so sharks are very sensitive to small differences in light intensity (dark versus light).
  5. Some sharks have a nictitating membrane, a type of second eyelid, that protects the eye during hunting.
  6. Sharks that live deeper in the oceans usually have larger eyes than those that live nearer the surface.
  7. A shark can see at a distance of up to 50 feet.

 

Smell

  1. Sharks have a excellent sense of smell. They are well known for their ability to detect minute quantities of substances such as blood in the water.
  2.  Sharks can detect a concentration as low as one part per billion of some chemicals, such as certain amino acids.
  3.  A shark’s sense of smell functions up to hundreds of yards away from the source.
  4. Water continually flows through the nostrils, giving the shark olfactory information.
  5. Unlike humans, shark nostrils have nothing to do with breathing and they are not even connected to the mouth. Their nostrils take in water and flush it out, picking up scents in the ocean.  It does not flow back into their gills.

There are so many fascinating things about sharks that would take all week to share with you. In my series, Brothers of Element, I tried to give every animal function a use when in human form.

Thanks for taking the time to share with us.

——–Drew has her first exam after going beneath the currents—–

Carina slid an arm through hers. “Are you alright, my Queen?”

“Yes. Startled, bewildered, and flabbergasted, but alright.” Even if none of this were true, there stood Dagger. She sighed. Little things he did endeared him to her more and more. “Question—birth control—tiger sharks carry over a year, with about eighty eggs fighting to survive.”

“Not in human form,” Dr. Sarah assured her. “And tiger shark women are only fertile every three years and have single or maybe a twin birth,” Dr. Sarah said, hands in her lab coat pockets, resting a hip along the sink. “Human fertility I have no experience with, although I have familiarized myself with the human anatomy in preparation of your arrival. Your spine shows a slight misalignment. The childhood injury I presume?” she queried. “The body protects itself when under attack and a pregnancy is an intrusion, a natural one, yet still an intrusion. I will have to go over the x-rays to be certain, but I do not believe this is a permanent state for you. Normally, I would recommend full bed rest after five months. In your case I will examine you after you meet Clear Coral.”

Tossing a look between women, Drew said, “And she will what?”

Dr. Sarah smiled as she uncrossed her ankles and said, “Our legend and existence stems from emotion. If you are whom we believe you to be, Clear Coral will comfort that which has been abused with in you.”

“Abused. You mean, it’ll fix what’s broken?”

“Precisely”

“And birth control?”

“Pregnancy is by choice. You request the male’s fertilizing sperm.”

She pinched the bridge of her nose. “I need to write this down.”

“We have surrogates… if pregnancy becomes detrimental to your health. And do not be concerned; our children do not take on their animal until adolescence. He or she will appear human in form, outside of their coloring.”

Carina added, “Tiger and bull sharks tend to show signs of change earlier than most other species.”

She scrubbed a hand up her arm to cover her shoulder and felt the shark under her fingers. She was becoming one of them.

 Drew’s in for an adventure. 

Sincerely, Cora Blu.

As the kids are hopefully back in school, I thought I’d give us all a little peaceful treat. Thanking you all for the loving support you’ve given my Brothers of Element Underwater Series and Contemporary Interracial Romance Collection, here is a glimpse into the ocean. 

Remember what our mothers said when we went in the store “See with your eyes not with your hands” Never touch the corals.

I hope you enjoy. Click on the link above to do a little wall diving. 

Thank you David for another great diving video. You capture the ocean like no other.

A Brothers of Element Series

For all those caught in the wake of hurricane/ tropical storm Irene, my prayers are with you and your families.

“Dagger’s Bite”

Tsunamis and earthquakes don’t just happen.

“Remember, you gave me your word, no swimming with the killer whale tonight,” Jack
reminded her. “We’ll go out tomorrow night, I promise.” His words tickled down
her face as he spoke against her temple. “The E.R. is swamped this time of year
Drew. Vacationers and saltwater.” He shook his head. “…a bad mix. So please no
killer whales tonight.”

Drew was the worst liar, but this promise she could make. She wasn’t looking for Bandit
tonight, she needed T-Bone, needed to vent. She had the dream–again. 

Besides she and Jack both knew dating with their schedules would be difficult…a Dr. and
a marine biologist. She’d need to have an accident just to get him alone for more than three minutes. At least then she’d be on a bed. If the hospital weren’t just up the street, this visit would be a text message. Absently she picked at the V-neck of his scrubs, smiling up at him. 

“Don’t worry about it…there’s other fish in the sea,” she joked. Biting her lip she
could’ve kicked herself. Why did she say that that? “Jack, I didn’t mean…”

“That’s not funny Drew,” he told her, backing them up to the deck railing. “I’m dating
Dr. Do-little.” Drew gave in to the pull and leaned into the loving caress, of his lean body. The faint scent of laundry detergent told her he’d thrown on fresh scrubs. He was still on duty. A clean masculine scent rose from his warm skin as his muscled arms closed over her back, pulling her tight to his chest. 

“I know I gave you a scare last time, but you have to believe me. If I felt unsafe, I would not have swum with Bandit.” She watched his beautiful soft brown eyes and knew their relationship wouldn’t survive another scare.  

“Drew, I see enough tragedy coming through Triage at the hospital; don’t have me working on you one night because Bandit or T-Bone used you for a volleyball or worse, they developed a taste for chocolate.” Jack complained and rubbed absently across
her back. She moaned low in her throat. He had the best hands. He stopped rubbing and peered down into her face. “You dove deep again today, didn’t you?”  

“…Sort of my job,” she said defending her actions. Cupping a hand over his hard jaw, she
stroked his five o clock shadow. “Jim’s always with me, so please, relax,” she added. Slipping her arms around his neck, she laid her face over his thudding heart and looked out over the gentle surf lapping at the footprints in the sand. It erased one day to prepare for the next. “I never go alone anymore.” The tension she felt in his body ran deep. His worry was for more than her stiff spine. He wasn’t telling her something.  

His shoulders dropped with a heavy sigh. “See T-Bone while you were down there?”
His tone was gently hostile, laced with accusation.  

She blew out the breath lodged in her throat and asked calmly, “What are you saying
Jack?”  

“I’m concerned that–”  

“I didn’t see him today.” Was he jealous of a shark? T-Bone had been with her for ten
years, he was like a pet. She never had a dog or cat. And she didn’t want to be frustrated with Jack. He was just concerned. Wouldn’t be Jack if he weren’t.  

“Has your spine been hurting all day?” he asked, his brow furrowed with deep grooves.  

“Off and on a little,” she admitted, and rose up on tip toe, kissed his chin. “Stop frowning. I took my medicine.”  

Jack picked her up and set her on the deck railing, catching her off guard. He slipped a hand over the nape of her neck and his mouth found hers. She leaned into the rough kiss—edged with frustration and fear–absorbing his body heat through the thin cotton of her tank top. The overwhelming worry in his embrace saddened her. Pushing away from his chest, she saw in his eyes the pain she’d felt in his kiss.  

She couldn’t keep hurting him this way. She needed more time to find out what was
going on, on the ocean floor. She could at least ease his fear for tonight. “Sweetie, I swear, I will not get in the ocean tonight,” she said, and hoped to calm his fear.  

“I wanna believe that, but I know you Drew.” He patted her hip, unlaced her hands, and
then stepped off the deck. “I can’t compete with a shark,” tipping his chin out toward the ocean. “You were waiting for T-Bone to push the volleyball back to shore when I pulled up tonight.” She had no response as he brushed sand off his scrubs, and moved down the driveway to his truck. She had been waiting. When he turned and their eyes met, she  new in that split second she’d lost him. “Friday, wait for me,” he said. “I’ll walk down to Jim’s party with you.”  

“Jack…wait.” She ran down the few stairs to the beach, a hand pressed to her back. And slid to a stop, toes planted deep in the sand, when he held up a hand. The hot pink glow of South Carolina’s sunset darkened his southern boy tan. It slipped behind her beach house, casting long shadows down the driveway, a fitting semblance with the shadow of doubt hovering over their relationship.  

“Maybe you were right Drew; you’re not ready to date. We’ve been friends for eight years, I won’t screw with that.” Closing the few steps between them, he moved behind her. Warm air hit her spine as he scrunched up her cotton tank top. “Hold this up.” She did without question. A warm press of lips touched the top of her spine. She pressed a hand to her lips, listening to his voice. “Martin was a great man and I realize continuing your father’s marine research is a huge part of your life. That’s not the problem here.” His long fingers slipped over her ribcage as he pressed another kiss to the center of her spine, making her breath catch before he said, “Malcolm’s death still haunts you.”  

A whimper left her chest and rode the warm air when his grip held firm on her hips. She
felt the moist heat of his mouth as he sucked the skin over the base of her spine.  

“I’ve wanted to taste you for years. Bury Malcolm, and then we’ll try again.” Drew
swallowed the lump blocking her throat as he smoothed her top down and then kissed the slope of her throat before walking past her down the seashell covered driveway.  

“It’s not just–Malcolm’s death,” she said. She let out a heavy sigh. “Jack everything
lately has been whacked out. Something is not right in the ocean.” She inched closer to him. “Jack, wait.”  

Leaning against the side of the house, she closed a hand over the latch on the side
door. Her breath came in stilted pauses, like scared little kids on a diving board, one at a time.  

“Jack, you’re a…a wonderful man, please…just be patient with me.” Taking a cleansing
breath, her heart beat gentled and her words lined up closer together. ”You know my father thought the sea floor showed signs of shifting,” she said. “These dives, and working with the animals, they’re important. You’ve seen the tsunamis and earthquakes popping up around the world. They’re coming from the ocean floor. I’m getting closer to the truth.” She squeezed back the tear threatening to fall.  

“The truth is, you think one of the animals killed Malcolm,” Jack said, almost whispered.
“I understand you need closure, so I’ll wait.” He blew her a kiss. “As your friend.” The low dings of the car door opening couldn’t drown out the metal door closing on their romantic relationship. “Goodnight sweetie. Lock up…I’ll always be your Jack.”

He slipped behind the wheel of his truck. Sand crunched beneath his tires as the tan SUV, crept down her street and out onto North Causeway. The tail lights slipped around the soft pine trees coated in sea-salt spray. Jack had been right, she needed closure. Unless sharks learned to speak, she would never find that closure.  

Thirty minutes later, fresh from the shower, she rubbed her puffy eyes. She’d cried
the entire shower, reminded of all her loses through the last ten years. Losing her parents, guardian Karen fiancé Malcolm and now her boyfriend. At least the boyfriend was still alive, correction former boyfriend. 

She feathered a hand through her short waves, stretched her arms up over her head,
and did a few downward dog poses to ease her spine. Well, no point in prolonging the inevitable.  

Flipping off the table lamp beside her bed, she pushed the window open and slipped
between the cool sheets. Closed her eyes…and waited.  

Who would the ocean send to visit her tonight? Maybe she’d do better with the blue-man
from the ocean. He preferred her wet. Had Jack known about the man from the sea? She bunched the pillow beneath her head, and then turned on her side. Great, now even she thought her ocean man was real.
