Sharks

Reef sharks primarily feed on fish, crustaceans, mollusks, and occasionally on invertebrates such as sea urchins and squid. They are opportunistic feeders and their diet may vary depending on the availability of prey in their habitat.

Because unlike other sharks, grey nurse sharks give live birth, other sharks lay water-proof sacks when nurse sharks have a placenta like other mammals. Seperating mammals from amphibians and repitles is if they gve live birth.

Actually all sharks are fish.

Blacktip sharks primarily inhabit warm coastal waters in tropical and subtropical regions worldwide, including the western Atlantic Ocean, the Indian Ocean, and the western Pacific Ocean. They prefer shallow waters near shorelines, making them commonly found in areas like coral reefs, lagoons, and estuaries.

It is uncertain as to where the word "shark" came from because before the 16th century sharks were known as "sea dogs". It is believed that the word came from the Yucatec Maya word "xok" which is pronounced "shok". Though there are speculations of sailors and fishermen in the 1400s and 1500s using the word "sharke" to describe certain marine creatures and fish.

Mako sharks are apex predators, meaning they are at the top of the food chain. However, larger sharks such as great whites and orcas have been known to prey on mako sharks. Additionally, humans are a significant threat to mako sharks through commercial fishing.

According to the 'Shark Extremes' link below, there are at least three contenders for smallest shark species. They are so similar that differences may be unimportant, and accurate measurements of unambiguously adult specimens are difficult to make. They are Etmopterus perryi, Squalidus laticaudus, and Eridacnis radcliffei.

The habitat of blue sharks can be either temperate or tropical waters. These pelagic sharks can be found in the Indian, Atlantic, Pacific Oceans, and worldwide in deep waters. The blue shark can grow up to 13 feet in length.

Common thresher sharks are typically solitary creatures, although they may form loose aggregations when feeding or during mating season. They are generally not social animals and tend to swim alone in the open ocean.

Yes. There are numerous species of Shark in the waters around Corfu. Including the fabled Great White (Carcharodon carcharias), but try not to worry, actual attacks on humans are very rare. There have only been 31 attacks on humans in the Meditteranean in 200 years. There is a breeding population of Great Whites in the area around Eastern Mediterranean, the Adriatic and Ionian Sea (around Sicily, Malta, the Ionian Islands). Possibly using Blue Finn Tuna as a food source. In 1987 Alfredo Cutajar casught a female Great White (all the largest Great Whites are female) off the coast of Malta, which was origanlly claimed to be 7.13 m (23.4 ft) long. However, are careful photo analysis the true size was calculated being closer to 18.3 ft (5.6 m), still a colosul specimen. Great Whites in this area seem to be larger than average, a specimen that killed a swimmer off Keratsini, Piraeus in 1948 was reported to be 6.4 m (21ft long).

On average, there are about 80 unprovoked shark attacks reported worldwide each year. However, the number of fatal attacks is much lower, usually around 6 per year. It is important to note that the risk of being attacked by a shark is extremely low compared to other risks.

sometimes THEY DO! sometimes THEY DONT!

A shark's spine is composed of cartilage, not bone. This helps sharks remain flexible and maneuver easily in the water. The spine also supports the shark's body and allows for efficient swimming.

No, they are omnivores and eat vegetation if they HAVE TO to survive. They are not COMPLETELY carnivorous(depending on species) My sources: http://www.deepseawaters.com/do-sharks-only-eat-meat.htm

the shark has about 85% of the body is cartilage because with out it they can not move as fast or as agile as they are with it

there are two chambers with a s shaped cosisting of the type of body plan they have

Some species of sharks are hermaphroditic, meaning they have both male and female reproductive organs. This allows them to switch between genders depending on environmental factors or social dynamics within their populations.

Some sharks swim by propelling themselves through the water using their tails, like great white sharks. The fins are only used for balance. Other sharks, like the whale shark, move their bodies from side to side to propel themselves through the water.

Sharks do not have scales like bony fish. Instead, they have rough, tooth-like scales called dermal denticles that provide protection and reduce drag in the water. These denticles also give sharks their rough texture.

The largest recorded shark mouth in history belonged to a 21-foot-long Great White shark, which had a mouth that was about 4 feet wide.

Sharks are predominantly found in saltwater oceans, as they are well adapted to survive in the marine environment. However, some species of sharks can also be found in freshwater habitats such as rivers and lakes.

Angel sharks are predators that primarily feed on fish, crustaceans, and mollusks. They are ambush predators that lie in wait for their prey, using their camouflage to blend in with the ocean floor before striking. They have sharp, pointed teeth that are used to catch and consume their prey.

No.

Most sharks stay only in salt water, and lakes are fresh water.

A few swim some distance into rivers, so for a shark to ever end up in a lake, the lake has to be connected to a river that runs out into the sea, and fairly close to the coast too.

Sharks are fish, while whales are mammals. Sharks have cartilage skeletons, gill slits, and scales, whereas whales have bones, lungs, and smooth skin. Sharks have multiple rows of teeth that are constantly replaced throughout their lives, while whales have baleen plates or simple teeth for feeding.

The lateral line of a shark is a series of small sensory pores that run along each side of the fish, typically from head to tail. These pores allow sharks to detect changes in water pressure and vibrations in their surroundings, helping them locate prey and navigate their environment.
