Killer whales are large overall and the males are definitely larger than the females. The males on average are from 19 to 22 feet long. Their shapes are made from swimming and are roughly cylindrical. Killer whales tend to be black and white with a gray spot behind their dorsal fins. They have pointy dorsal fins and a full row of sharp teeth in their mouth and fins to help them
Whale Sharks the largest fish in the world and are found throughout the warmer areas of the oceans. Whale sharks can reach to 18 – 40 feet long and weighing from 12 - 20.6 tons (Bradford A. 2016). As filter feeders, whale sharks eat mostly plankton and other small organism such as zooplankton, copepods, shrimp, phytoplankton, mollusks, and sardines. Whale sharks capture their food by swimming towards it with their mouth open which can get up to 4.9 feet wide and engulfing their prey that enters their mouth (Rafferty J.
5) No scuba diving allowed. 6) No flash photography allowed. 7) Absolutely no feeding of fish allowed Here are some interesting facts about whale sharks you ought to know: -They are the largest fish on earth - They are not related to whales but are a type of shark; a very tame shark which feeds mostly by filtering plankton. - Whale sharks can reach weights of up to 12,000 kilos, or 24,000 pounds!! -A whale shark needs to move its whole body from side to side in order to swim, so it can only reach speeds of up to 5km/hr.
Sharks have existed for over 400 million years, predating insects, mammals and dinosaurs. Being the apex predators of the world’s seas, sharks have been keeping the population of the oceanic ecosystem in check. However, the number of sharks is considerably decreasing. One of the main reasons behind this is shark finning, the brutal and barbaric practice of cutting off sharks ' fins then throwing the rest of the body, often still alive, back into the sea. The practice of shark finning should be banned worldwide.
However, I caught a 42 inch shark in Florida (saltwater) which took me 20 minutes to reel in, and that is considered a small fish. They both have unique characteristics that make them completely different things. I’m going to prove that all fishing is not the same, saltwater and freshwater fishing are different sports based on dangerousness, cost, species, bait, and boat type. Most people assume fishing is a safe and easy hobby, however, fishing can actually be a dangerous activity. Saltwater fish have the potential to pull you into the water, bite you, or even sting you.
These are 3 reasons why the killer whale is the ocean’s top predator. Their physical characteristics are appropriate to hunt their diets. Junior Explorers said that the killer whales are the largest of the dolphins and one of the most powerful predators of the
Over 100 million sharks are murdered by humans every year, and it’s a high number for any animal but it’s endangering to sharks because they don’t breed very quickly due to their biological composition (NewsCurrents Read to Know). Sharks reproduce very slowly and they can’t keep up with the rate that humans are killing them off at. With that inbalance, they’re getting closer and closer to extinction everyday, but with a ban on finning that would cut down over half of those casualties and keep the sharks from dying off. Consequently, because they’re being killed off in large unmoderated amounts there a species of sharks already extinct and in "Bad to the Bone", written by Michael A. Rivlin, he writes “Because of such biological profiles, most shark fisheries have experienced brief booms, followed by long busts. To take one notorious example, in 1961 Norwegian longliners began catching porbeagle sharks in the Northwest Atlantic.
One of the most well-known vulnerable bear species is the polar bear, these bears are found exclusively in the arctic across Alaska, Norway, Canada, Greenland and Russia. Polar bears are seen along the coasts and on islands, they are very often found out on the ice across the sea. These bears feed mostly on seals and so the ice is of huge importance out at sea, polar bears travel across this ice while looking for seals between the gaps and spaces. Polar bears are extremely strong swimmers and can travel kilometres in distance searching for suitable spots to try and feed, although they are strong swimmers they are not fast enough to keep up with seals
Sea otters are omnivores as they do eat kelp and other sea-going plants. Regardless of this however, most sea otter people have an essentially flesh eating diet with sea otters known to eat more than 40 unique types of marine creatures. The sea otter chiefly chases ocean urchins, mollusks, crabs, snails and little fish in the water. The sea otter is one of only a handful couple of creatures on the planet that has the striking characteristic of utilizing devices, for example, rocks, keeping in mind the end goal to get at it 's prey. Sea otters have couple of normal predators in the ocean because of their vast size.
However, when the whales are put into tanks they experience many more dangerous medical conditions. “Killer whales are known for their impressive dorsal fin, which in males can reach 1-1.8m tall. But, in captivity, they collapse”(Warley). In Seaworld most of the whales have collapsed fins that are turned over and are no longer straight. In the wild only one percent of dorsal fin collapse happens among whales.
