Sharks

The second heaviest shark is the tiger shark (Galeocerdo cuvier). They can weigh up to around 1,900 pounds (900 kg) on average. Great white sharks are usually considered the heaviest shark species.

The dwarf lanternshark (Etmopterus perryi) is considered the smallest and lightest shark species. They typically grow to be about 8 inches in length and weigh less than a pound.

A bull shark typically has around 50-65 rows of teeth in each jaw, with each row containing about 7 teeth. This means an adult bull shark can have around 300-350 teeth in total. They constantly shed and replace their teeth throughout their lifetime.

Australia is known for having the world's largest reef, the Great Barrier Reef, and that is home and sanctuary for millions of fish, and thereby sharks. They will tend to go where there is an ample food supply. And the reefs are thriving at reefs! Smaller sharks like to hunt there, because of the vast assortment of fish, think of a reef as a buffet! They can hear all the fish they want when it gets dark. Humans swimming anywhere near a reef or drop-off are putting themselves on the list! It is that simple. As a rule, sharks don't want to eat humans. They will look for seals, pinipeds, and young whales because of the high blubber content

Almost every animal lives in one specific biome. A killer whale (and all whales) live in the ocean or marine biome.

Zebras are can be a wild animal if they don't belong to a zoo, so zebras live in the wild. Places such as Africa are where zebras live

The Pacific Ocean is home to the most diverse population of sharks, with over 300 different species known to inhabit its waters. The warm waters of the Pacific provide an ideal environment for sharks to thrive and there are many popular shark diving destinations in the region, such as Hawaii and Australia.

There are just 67 deaths by sharks in the whole world. Often the shark may see a flash of white (a person's leg or arm) and mistake it for a fish. Sometimes people in dark wet suits are mistaken for seals. Many sharks are simply curious like dolphins, but since dolphins are of no threat and love to play with humans, the shark is menacing looking and the blame has been laid by scientists on the movie JAWS.

1,000 people in the world drown for every shark attack or shark related death. Believe it or not (by scientists studies) for every 60 bites from a shark there are 25% of New Yorkers that bite each other!

Much of the blame for a frenzy of sharks coming closer into shores of beaches is blamed on 'baiters' for tour boats. They throw out blood and entrails of fish to entice the sharks just so the folks on the tour boats can see a real live shark. One shouldn't play with mother nature!!! Now surfers and other beach goers are blaming these shark tours for more sharks sticking closer to shores of beaches.

I've read many stories where a shark has been curious over a human and circles them. They may come close and all it takes is a punch on the end of their nose or a poke in the eye if the person in the waters feels the shark is getting too close and generally the shark will leave. If there is a feeding frenzy going on with sharks with a large group of fish a diver may get mixed up in the whole thing and be bitten or chewed to death.

Sharks are one of the oldest creatures besides the Blue Whale in the world. It would be a terrible thing if people were so ignorant they didn't educate themselves on sharks and realize they help clean up our oceans and have a reason for being there. Like any animal that is wild, one should learn about them, respect their turf and coincide with nature. If people persist on taking chances or not reading signs that are apparent on many beaches of shark warnings then they pretty much get what they deserve. Many of the people who have reported shark attacks have actually been divers and some surfers.

I agree with baiting for sharks and that they cause an imbalance of nature bringing the shark closer to crowded beaches or coastlines.

Should we kill sharks? No! We are the interlopers in their turf and we should respect the warnings.

Small sharks are often referred to as "pups" or "juveniles." They can also be classified based on their species, such as "dwarf lanternshark" or "dwarf catshark."

great white shark The great white shark is fat but when it bites you it crushes you.

And there is a really low chance that megaladon sharks are in our planet, because none people we attacked by a megalodon shark before

yes

No! They are made of cartilage.

Sea lampreys are parasitic fish that feed on the blood and body fluids of other fish and sometimes on mammals. They use their suction-cup mouth and sharp teeth to attach to their prey and then use their rasping tongue to suck out the fluids.

Sharks may avoid attacking prey if dolphins are present because dolphins are known to exhibit aggressive and protective behavior towards potential threats, including sharks. The presence of dolphins can create an unpredictable and risky situation for the shark, which may deter them from attacking. Additionally, dolphins are fast and agile swimmers, making it difficult for a shark to successfully catch their prey in the presence of dolphins.

Shark have gills, just like fish, that water flows through. Oxygen in the water is absorbed by blood rich capillaries in the gills, which then circulates the oxygen to the rest of the sharks body.

Yes, a shark is considered a secondary consumer in the food chain, as it feeds on smaller fish and other marine animals that are primary consumers. This places sharks one step higher in the food chain than the primary consumers they consume.

Mother sharks are made through the process of reproduction, where a female shark mates with a male shark to produce offspring. Sharks are ovoviviparous, meaning the embryos develop inside eggs within the mother's body until they are ready to hatch.

Yes Sharks have gills, they are five slits located just in front of their pectoral fins.

Without Gills a shark would not be able to breathe underwater.

Its true.Sharks swim while they sleep.The reason they do that is because in order to breathe they need water running through their gills all the time.So when they sleep they move to keep breathing.If they stop moving THEY CANT BREATHE AND WILL DIE!!

Shark dorsal fins are typically straight and rigid, while dolphin dorsal fins are curved or falcate. This difference in dorsal fin shape is one of the visual cues you can use to differentiate between sharks and dolphins in the wild.

Most sharks live on the South American coast because of the warm water. But some sharks, for example, like the Greenland shark live in cold waters because its like they're blood flow. You're in luck most shark's around America do not attack

The common name for the Alopiidae family is thresher sharks. They are characterized by their long, whip-like tail fins that they use to stun prey.

Baby leopard sharks may be eaten by larger predators such as other sharks, seals, and larger fish. Additionally, birds of prey like eagles or ospreys may also prey on baby leopard sharks in shallow waters.
