They are good hunters that eat a large variety of fish, squid, sharks, marine mammals (such as whales and seals), turtles, octopi, and birds (penguins and gulls). They have 10-13 pairs of large, interlocking conical, enameled teeth in both the upper and lower jaws (the orca has from 40 to 52 teeth). The teeth curve inwards and backwards, which helps the orca catch its prey. Teeth average about 3 inches long and about 1 inch in diameter, but some are even longer. Members of a pod often cooperate in hunts.
The pots were about 3 feet 6 inches and contained two to three dozen good size crayfish weighing about two several pounds. The men said it was about one hundred and fifteen to three hundred feet long. Another eyewitness saw a great white shark the size of a tractor trailer had attacked a person. Many sharks have been clocked out as fast as 1.5 miles and the mega shark could probably swim in a longer distance since this is a bigger shark. Two percent of the ocean has been overlooked by people ant it leaves ninety-eight percent of the ocean for the megladon can swim.
After so many years and incidents, the captivity of killer whales or orcas (Orcinus orca) merely for entertainment purposes should be prohibited. The limitation of space and most important the deprivation of freedom modify the behavior of orcas making them aggressive, even depressive and prone to hurt themselves and the humans who interact with them. With a brain four times larger than the human brain, the killer whales are among the most intelligent species in the world (Kirby 2). Studies have shown that their brains are more complex than human’s. The orcas’ brains have an “extra” part that makes them considerable more emotional.
The Oceanic White-Tipped Shark is a pelagic shark which means it lives close to the surface and rarely goes to the ocean floor. It is an aggressive slow moving fish that usually will find a carcass of a whale or other large marine animal and dominate the feeding frenzy. It gets its Name white-tipped shark because every fin on the shark has a white tip except the anal fin which has a black tip. They inhabit most of the Salt water of the world because they can live in cold or warm water. Excluding the occasional feeding frenzy, white tips also eat a diet that consists mostly of cephalopods.
They allow the writer to add a comparison, which in return makes the reader start thinking. Doyle uses the comparison of a whale’s heart and a saloon’s doors by stating, “The valves are as big as the swing doors in a saloon” (29). This comparison allows the reader to visually see those doors opening and closing and then picture their surroundings to be inside the heart. Another simile in Doyle’s piece occurs when discussing the size of the whale’s heart. When he says, “The biggest heart in the world is inside the blue whale.
There are many different species of Algae which can range in size from microscopic to a couple meters long. Phytoplankton is at the bottom of the food chain and is eaten by small crustaceans which are called Zooplanktons. Zooplanktons are eaten by fish, invertebrates, mollusks, ducks, and turtles. • Plants: Around fifty species of food and shelter providing plants- Plants along with Algae provide the Rideau River with oxygen. Some of the plants in the Rideau River are carnivorous.
They need to feed their chicks and the colonies are often a long way from the fishing grounds. Each chick needs about 42 kg of food from each parent.The entire breeding population of emperor penguins may consume as much as 1,500,000,000 kg (1,500,000 metric tons) of krill, 115,000,000 (115,000 metric tons) of fishes and 3,500,000 (3,500 metric tons) of squid each year. Method Of Collecting And Eating Food Penguins feed at sea. Most feeding occurs within 15.3 to 18.3 m (50-60 ft.) of the surface.
The resulting anxiety and tension cause fights between orcas. In the wild, orcas have strong social bonds that may last for life, their social rules prohibit serious violence against each other, and when fights do occur, they can find space to flee. In captivity, there's nowhere for them to go, which leads to injuries and death.” (SeaWorld of Hurt) Besides fighting with fellow killer whales, Orcas are biting the bars, concrete and tanks to escape due to stress and anxiety. The diet of a whale in captivity is unlike the diet of a whale in the wild. PETA’s campaign SeaWorld of Hurt shares, “In captivity, orcas are unable to hunt and obtain water from their prey, so SeaWorld gives them gelatin, a substance that is not natural for them, in an attempt to keep them hydrated.
Adults tend to eat sea grass and algae. Green Sea Turtles who live in aquariums are fed romaine lettuce, gel food made from algae, and a balanced mixture of essential vitamins and minerals. Unlike regular turtles, a green sea turtle’s shell has evolved so that they can propel through waters at a great speed when needed. Their front flippers help them to do so, as well. A green sea turtle’s carapace has a mottled brown top with a creamy white color under its shell; which is often covered in algal growth.
Some manta rays live in a particular location while others travel from places to places. Manta rays are filter feeders. They consume a large quantity of zooplankton by filter seawater through their mouths while swimming. And usually many manta rays swim in lines with their mouths open to filter more zooplankton. Manta rays are huge in size so only sharks and killer whales can harm them and eat them.
