But here some qualities that sharks do to help our planet. In fact Sharks keep the ocean food chain in check. They do this when sharks eat seals and it keeps the seal population normal, but if there were no sharks the seal would overtake fish and squid population until they would just go extinct. Another thing sharks do to help our planet is they hold cures for human diseases. They have special characteristics that could be turned into ingredients to help find cures.
These predators will eat fish, dolphins, turtles, birds, and other sharks. Bull sharks have a specific technique when they stalk. It is called the bump and bite method, and begins with the shark bumping its prey to disorientate and/or kill. They will then impale its lower jaw into its target, and then swing its head side-to-side with its upper jaw to take tissue from its victim(sharks.org). Sometimes, the sharks will hunt in groups.
Another reason why sharks should be preserved is because they play a crucial role in the ecosystem in the ocean .There are many species of sharks throughout the ocean, and these sharks feed on a very diverse diet throughout the ocean. Sharks can feed on large game like seals, sea turtles and whales, depending on their size. Smaller sharks feed on things like small fish, crustaceans, and even other sharks.
Sharks have been swimming the world’s oceans for more than 400 million years - 100 years before the first dinosaurs appeared (Griffin et al., 2008). Sharks fall under the kingdom Animalia, the phylum Chordate and the class chondrichthyes. There are more than 400 known shark species found in the ocean (Musick and Musick, 2011). In the ocean, sharks help maintain the health of ocean ecosystems and help regulate and maintain the balance of the marine environment (Griffin et al., 2008). These sharks have slow growth rates and reach sexual maturity at a relatively late age compared to other marine fish, which leaves their population vulnerable to any outside sources (Musick and Musick, 2011).
Feeding habits: Sea Lions are carnivorous having fish being their favorite food including herring, mackerel, pompano, salmon, capelin and squid. They also feed on crabs and clams. The quantity of fish consumed by sea lions depends on their size as well as the abundance of fish in their habitats. Sea lions may use their sensitive whiskers to locate food.
However, they have been seen in groups around carcasses. Great whites must swim constantly, or they will drown. They are able to travel vast distances thanks to their powerful bodies. All sharks have a distinct appearance, and the great shark is no exception. They have a pointed snout and a large, torpedo-like body.
Last two representatives of the huge terrestrial fauna kill around 100 people each year, while sharks have around five victims on their account. Meanwhile, tigers and elephants already had law protection, when the documentary was created, while sharks were treated as a source of valuable product (their fins) and a monster that should be killed before it would get an opportunity to attack. Numbers, mentioned by the film, created the impression the situation is totally unfair. As if officials today will forget about their efforts against the ivory black-market
They are likely to compete for resources like food and shelter on land or in the ocean with other species of animals also living there. b. The hypothesis she was testing was: The distribution of the crab is determined by osmoregulatory physiology. Her results showed that the U. imadeitupensis do not survive more than 2 weeks in the marine enclosures. c. It looks like the U. imadeitupensis started to compete with the U. imaginariensis after 48 hours in the same marine enclosure.
Common bottlenose dolphins and killer whales are the most well-known types of the dolphin on Earth. Both of them are warm-blooded marine mammals belonging to the Delphinidae family. The scientific name of the common bottlenose dolphin is Tursiops truncatus, which means “dolphinlike”, and the killer whale is Orcinus orca, which means “of the kingdom of the dead”. This name is likely a reference to killer whales’ outstanding hunting skill. In Latin, orca means "large-bellied pot or jar".
