They have been known to feed on fish, dolphins, whales and seals. Sharks prefer meals with a high fat content to give them energy. They are ambush hunters, taking their prey by surprise from underneath. They have been known to come up from the bottom so fast that their entire body has left the water. The Great White has only one natural predator, the orca.
Most jelly fish are dangerous as they sting other creatures, when touched by one of their tentacles. Clown fish are immune to stings thus why Marlin wasn’t affected. 14. Compare Dory, Bruce and Nemo, which is the best adapted for speed and why? Bruce is best adapted for speed, as he is a shark and needs to be fast to catch and hunt down his prey.
Younger lionfish have a unique tentacle above their eye sockets, which differs in appearance between species, but studies show that this tentacle has evolved over time in each species serving to attract new prey. Juvenile lionfish eat mostly invertebrates, but shift their diet to fish as adults and eat reef fish. Adult lionfish spread their pectoral fins and use them to "herd" prey. This is a very effective predatory style because it is unfamiliar to native Florida fish. However, Lionfish can have negative effects on the overall reef habitat as they can eliminate organisms which serve important ecological roles such as herbivorous fish which keep algae in-check on the reefs.
Their narrow pointed teeth are ideal for holding prey, most of which is swallowed whole. Tests on the feeding habits of angel sharks have shown that they react to any passing prey, spitting out anything that does not appeal to their appetite. They have complete faith in their camouflage when approached by divers but will inflict a shallow bite if harassed. The various species of Angel sharks range in size up to 6.5 feet (2 m) long and are mostly bottom dwellers that live on ocean floors of depths from 10 to 4,300 feet (3 to 1300 m). They sometimes prefer however, sandy near shore habitats.
Dissolved oxygen levels can also cause fish to suffocate and be more susceptible to diseases. Construct a hypothesis – Based on your observation in Question 1 and your background research in Question 2, develop a hypothesis statement that addresses the relationship between dissolved oxygen in the water sample and the number of fish observed in the body of water. Answer = If the dissolved oxygen level is high in a body of water, there will be a low number of fish. The higher the dissolved oxygen level the higher the death rate of the current fish. 3.
Two percent of the ocean has been overlooked by people ant it leaves ninety-eight percent of the ocean for the megladon can swim. This shark could be a very intelligent shark by possibly attacking its pray as fast as it can and head down the bottom of the big blue. The evidence has proven that there was a time this shark had lived because of the physical evidence shown by the teeth collected. The pictures clearly state that there is a mega shark out there and the eyewitnesses explained that a huge shark had been around in South Africa. There may come a time when this shark may make a mistake and show its self to the world with
That was just mind blowing to me and it showed why this business of shark finning is such a huge business. Also the movie talks about line fishing which I have never heard of before this video. Line fishing is when a fishing boat takes miles and miles of fishing line full of baited hooks and tosses it out in the water for fish, sharks, turtles, or just any type of sea creature to bit or get tangled in and die. Line fishing is illegal in most countries but there is such a huge business in it a lot of countries will not do anything to stop the fishermen from doing it. For example when Rob and the crew of the Sea Shepard were trying to stop the Varadera from line fishing the Varadera crew was let off the hook by the Costa Rica government even though they were illegally fishing, but the Sea Shepard was charged with 7 counts of attempted murder.
Other researchers think some people were trying to breed Snakeheads as they bring a large amount of money in some areas. (Frankenfish.com). The Northern Snakehead is a major predator, as it has no enemies. It has the ability to wipe out populations of native fish. “Frankenfish” entire diet mostly contains other fish, as well as plants and insects.
The Megladon fish has disruptive coloration, with its spots and stripes it is able to confuse their predators. The Megladon is usually all different colors. The coloration also gives off the warning of being poisonous or that they taste bad. The colored pigments in the fish are found in cells in the skin called chromatophores. The chromatophores allow the fish to rapidly change color by contracting and expanding the pigment in the chromatophores.
This then has a large impact on the economy of local communities who rely on these scallops for a steady income. Peter Trott, who manages the fisheries program at the conservation organisation WWF Australia, says a decline in Australia's coastal sharks could have a similar effect on herbivorous fish. "With an explosion of numbers in rays they would just mow algae and weed down, so there's no habitat left for juvenile fish." "You'll also see an explosion of weak and sick fish, which isn't good for genetic
