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.
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.
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
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.
The length of the Great Barrier Reef is 1,553 miles long. An abiotic component is a non-living organism that is physical rather than biological. A biotic component has life or living organisms. Hermatypie corals are types of abiotic components that help the coral in the Great Barrier Reef. This refers to the very colorful Zooxanthellae algae.
Problem: What are the internal and external structures of a sea star? Hypothesis: I will examine the external and internal characteristics of a sea star. Since they are members of the phylum Echinodermata, they may have tough outer surfaces with spines. Their internal systems may consists of a mouth, stomach, digestive glands, and an anus. Materials: - preserved sea star - plastic gloves - dissecting pan - scalpel - dissecting scissors - dissecting probe - lab apron - eye goggles Procedures: Part A: 1.
One amazing species (Birgus latro) can climb coconut trees, cut a coconut loose, and can make a hole in a coconut so it can eat the inside! (I'm not making this up!) They do all have to return to the water to reproduce however. Did you know that hermit crabs are not considered true crabs? Two big differences are seen in the legs and the antenna.
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.
Construct a hypothesis – Based on your observation in question 1 and your background research in question 2, develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water? Answer = I would test the dissolved oxygen in different areas of water, keep track of the fish in those areas and compare the results. 4. Test with an experiment – Describe an experiment that would allow you to test your hypothesis from question 3. This description must provide ample detail to show knowledge of experimental design and should list the independent and dependent variables, as well as your control.
With over 1m wild alligators in Florida versus a human population of 17m humans, there’s lots of opportunity for conflict. The beasts can grow to 12ft and their lethargic appearance has misled many a startled holidaymaker, within a flash they can snap their jaws and even run up to 30m.p.h. There are actually Gator Hunters operating in Florida to deal with the problematic reptiles. Obviously the animals know no boundaries but they do not seek human attacks and they usually try to avoid us, however sometimes things go wrong. Pestering, tormenting and throwing food to gators is usually the root cause.
