Sharks

Sharks can only see in shades of grey.

Findings from a study by Australian scientists, released in September 2012, show that sharks' eyes have just one type of cone opsin - or light-sensitive proteins found in the photoreceptor cells of the retina - instead of the two or more that are needed to see colour. Cone opsins are used to help animals see in bright light, and to differentiate between colours.

Great white sharks and thresher sharks do not have the same order in their taxonomic classification. Great white sharks belong to the order Lamniformes, while thresher sharks belong to the order Lamniformes.

There is no direct link between global warming and shark attacks. On average, worldwide shark attacks result in about 10 fatalities each year, with fluctuations due to various factors such as human behavior and shark populations. Global warming may impact the distribution and behavior of sharks, but it is not a direct cause of shark attacks on humans.

Shark populations have declined significantly over time due to overfishing, habitat destruction, and climate change. Many shark species are now threatened or endangered, with some populations decreasing by as much as 90%. Conservation efforts are being made to protect sharks and their habitats to help stabilize their populations.

Bare bottom sharking is when a prankster pulls down the pants or up the skirt/dress of an unsuspecting female then (in most cases) runs away. If the woman is wearing panties/underwear, some pranksters will attempt to pull down these as well, and then spank them. Most offenders have a partner with a video camera filming the event from a distance or in a discreet location.

eels live in salty water they can't live in normal water because they can't get their electric shocks on

Searching for websites that depict explicit animal mating behavior, including sharks, is not recommended as it goes against promoting respectful and educational content. Instead, consider searching for scientific articles or documentaries that discuss shark mating behavior in a appropriate and informative manner.

The largest shark species is the whale shark, which can grow up to about 40 feet in length. This gentle giant is a filter feeder, meaning it primarily consumes plankton and other small organisms by filtering them out of the water.

Their body is stout. The nurse shark can be many different colors, from yellowish tan to dark brown. Instead of the pointy dorsal fins, nurse sharks have rounded dorsal fins on their back, the first one bigger than the second. Nurse sharks have extremely long caudal fins, or tails. The bottom fin, the pectoral fin, helps the nurse shark to hover, and sometimes even to "walk" along the ocean floor. The shark has a precaudal pit but no caudal keels.

One of the distinguishing features of nurse sharks are their barbells - fleshy appendages which hang below their nostrils and, in part, provide a sense of touch which assists in the location of prey along the bottom. Female is always slightly larger than the male of the species.

Abiotic factors for bull sharks include water temperature, salinity, and oxygen levels. Biotic factors include their prey, such as fish and other marine animals, as well as competitors within their ecosystem.

No, sharks do not breathe air. They have gills that extract oxygen from the water as it flows over them, allowing them to extract oxygen from the water and breathe efficiently in their underwater habitat.

Most people would say that it is the Great White shark, but it is really the third heaviest. The heaviest shark is the Whale shark at 13.6 tons (43 feet), and second is the the Basking shark at 4.5 tons ,the Great White reaches a mere 2.3 tons. ______________________________________________________________

No, sharks cannot shoot webs. Sharks are fish and do not have the ability to produce silk like spiders, which is necessary to shoot webs. Spiders are known for their ability to shoot silk threads to build webs for catching prey or creating shelters.

DOGFISH In these times of dwinding fish stocks,the loss of many of prime food species has ment that previously unwanted fishes have thrived.This includes many of the dogfish sharks,which in the past have been considered merely as pests cause of them robbing bait on anglers.They are comman on all insores in all sea and weather conditions around the oceans of the world. LESSER SPOTTED DOGFISH The lesser spotted dogfish is the smallest and most comman member of the dogfish family .It is a cousin of the pyjama shark these fish are targets for the novice and junior anglers because u can catch them from the sore in all sea around the world and will take any fishy bait that is put to them,they are not know for putting up much of a fight when hooked by anglers. HISTORY TIP The dogfish's skin is like sandpaper in medieval times was used to scrub the decks of ships.

Dolphins are known to defend themselves against sharks and have been observed to chase them away in the wild. In some cases, dolphins have been known to injure or even kill sharks in self-defense or during competition for food. It is not common for dolphins to actively seek out and kill sharks as their primary source of food.

Sometimes, Nurse sharks are called giant sleepy sharks. Sometimes, Nurse sharks are called giant sleepy sharks.

No they are predators which makes them consumers.

Nothosaurus is believed to have been an aquatic reptile that lived in both fresh and saltwater environments. Fossil evidence suggests that it was capable of covering long distances at sea but may have also inhabited coastal areas and river systems.

To keep a freshwater shark alive, make sure the tank is spacious enough for it to swim and have hiding spots, maintain proper water conditions with regular water changes and filtration, feed it a varied diet of meaty foods, monitor its behavior and health regularly, and consult with a veterinarian specialized in exotic aquatic animals for guidance.

20-100 years of age

Goblin sharks are not considered dangerous to humans because they live at depths of over 300 feet and are rarely encountered by people. However, they have been known to bite when caught by fishing gear or provoked, so caution should always be exercised around them.

We really don't know. It's difficult to tell how many eggs in all were produced were because the pups (baby sharks) eat eggs-- and each other-- while inside her.

Mako sharks aren't egg-layers; they do live birth. They start when they're about six feet long but they can grow up to around 12. A litter is generally 4-16. Larger sharks give birth to more pups.

Similarities: Both dolphins and sharks are marine animals that belong to the class of fish. They both have streamlined bodies, fins for swimming, and are carnivorous.

Differences: Dolphins are mammals, while sharks are fish. Dolphins give birth to live young and nurse them with milk, while sharks lay eggs or give birth to live young. Dolphins are known for their intelligence and social behavior, while sharks are more solitary animals known for their hunting prowess.
