Theme Shark

Introduction

Today I’m talking about Sharks why because  this is an animal that interesters me and I am also teaching you about Sharks lives.

Appearance

The spined pygmy shark, a deep-sea shark, is one of the smallest at only about 7-8 inches, while the whale shark is the largest shark, and fish, at about 50 feet in length. Only 39 shark species are known to grow more than 3 m (10 ft.) while 176 species stay under 1 m (39 in.) in length. The spined pygmy shark (Squaliolus laticaudus) is probably the smallest of all sharks. Females reach about 18 cm (7.1 in.) in length while mature males may only be 15 cm (5.9 in.) long. For most shark speices, Females grow around 25% more than Males. The largest batoid is the manta ray (manta birostris) which reaches widths more than 6.7 m (22 ft).

Habitat

Sharks have adapted to living in a wide range of aquatic habitats at various temperatures. While some species inhabit shallow, coastal regions, others live in deep waters, on the ocean floor and in the open ocean. Some species, like the bull shark, are even known to swim in salt, fresh and brackish waters.

Diet

Most species of shark eat things like fish, crustaceans, mollusks, plankton, krill, marine mammals and other sharks. Sharks also have a very acute sense of smell that allows them to detect blood in the water from miles away.

Enemies

Think sharks are dangerous?  The most dangerous sharks are the Great White shark, the Tiger shark, the Hammerhead shark, the Mako shark and the Bull shark.  On average, there are only about 100 shark attacks each year and only 10 of those result in a human death. You should check it out from their perspective, though!  People kill thousands of sharks in a year for sport and for food.  Shark skins are used to make products like any other leather would be.  Up until the 1950's, shark livers were used as a vitamin A supplement.  Shark fin soup and shark steaks are both eaten in many countries (Mako, seen in the top photo, is the most popular in the United States).

Life Cycle

Each shark species has its own expected life span and it is difficult to set an average for sharks as a whole. However, very broadly speaking, most sharks live for between 20 and 30 years. The Spiny Dogfish lives for over a century, and some Whale Sharks have been known to do the same.

Unlike most other animals, sharks generally do not care for their young. As soon as pups are born into the water, they swim away and care for themselves. Some sharks give birth to litters of up to 100 babies at a time, while others may have as few as two or three. The Great White Shark gives birth to approximately three to 14 pups at a time. In almost all cases, all of the pups are beable and well-developed. This is in stark contrast to many other animals (such as several fish species and some turtles), which give birth to large numbers of ill-developed young (in effect, producing quantity over quality).

Behaviours

Most sharks are especially active in the evening and night when they hunt. Some sharks migrate over great distances to feed and breed. This can take them over entire ocean basins. While some shark species are solitary, others display social behavior at various levels. Hammerhead sharks, for instance, school during mating season around seamounts and islands. Some shark species, like the great white shark, attack and surprise their prey, usually seals and sea lions, from below. Species that dwell on the ocean floor have developed the ability to bottom-feed. Others attack schooling fish in a feeding frenzy, while large sharks like the whale and basking sharks filter feed by swimming through the ocean with their mouths open wide, filtering large quantities of plankton and krill.

Conclusion

So if you like my report write a shark report too like I did if you know how to write a report. So if you forgot what my report was on today it was a shark because this animal mostly interesters me most out of all of the animals. Next time I’m going to write a report on something that interests me.
