Neil chose to look in sedimentary rocks, such as limestone, sandstones, siltstones and shales, because they form fossils gently since they generally are formed by rivers, lakes and seas. At first, they were looking for fossils in the Devonian rocks in Pennsylvania, but they did not have much luck since the rocks had too much exposure. So they found that the High Arctic of Canada was ideal because the rocks were 375 million years old, they were sedimentary and had little exposure. Webbed fins, a flat head, a neck and scales on its
The northern snakehead preys on zooplankton, smaller fish, fish larvae, crustaceans, frogs, insects, small reptiles, and even small mammals and birds. In the areas in which the northern snakehead has invaded, native populations are having gradual decreases because of the northern snakehead’s unextinguishable appetite. The most notable features of the northern snakehead fish are its snake-like characteristics. The fish has a long cylindrical body with the blotchy coloration and patterns of a snake.
How much do you really know about the hammerhead shark? Most people assume a shark is a shark, but there are many different types of sharks all with their own distinct qualities. However, the nine species of hammerhead sharks are easily identified by the unique shape of their head which resembles a hammer and is the origin of their name. Hammerheads are cold-blooded mammals that can grow up to 25 feet in length and weight as much as 1000 lbs.
Originally found in the Atlantic Ocean, the sea lampreys where first discovered in Lake Michigan in 1936. The sea lampreys can be described as jawless parasites with mouths similar to suction disks. They also have very sharp teeth which they us to attach themselves to fish in the water, allowing them to feed on their blood and body fluid for various hours or even weeks. This usually causes visible injures to the bigger fishes and kill smaller fishes. These sea lampreys contribute to the decline in the population of white fish in the great lakes.
Author Peter Benchley was born in New York City in 1940. Over the next 65 years, he became one of the most widely-known and respected conservationists in the world. He used the acclaim from Jaws to alert the world to the growing danger of sharks, other sea creatures and the oceans themselves. Before the publication of the book in the 1970s little was known about sharks. Benchley wrote Jaws based on his imagination and the memories of summers from Nantucket, Massachusetts.
The Great Hammerhead Shark has many physical attributions that make the species unique to other sharks. Perhaps its most well-known anatomical feature, the flat and t-shaped cephalophoil, aids the Great Hammerhead in catching prey. Ampullae of Lorenzini on the hammer-shaped head sense hidden prey, which especially benefits the hunting of stingrays. The variations within the cephalophoils differentiate hammerheads from each other. In addition, wide-set eyes give The Great Hammerhead shark a greater, more enhanced range of sight.
It lives in waters around 3000m deep. They can live in any open ocean. The Hammerhead was discovered in unknown time by an unknown discoverer.

About 3 or 4 years ago my two cousins and I went deep sea fishing with are dads. We went so far off the coast of Florida you couldn’t see land at all. When we got back ( I was the only one who caught a shark he was a small Hammerhead) from the fishing trip we went back to our condo. Since then I have never caught a shark.

Dogfish sharks are very easy to tell the difference if it’s a female or male.
The ocean abounds with interesting animals of all shapes and sizes that have their unique appearances and habitats at different depths of the sea. The viperfish is a type of fish that lives at nine thousand feet under water and it is extremely dark down there. At this depth, the faint light that is visible down there helps the viperfish to blend in to hide from predators because they have photophers, little organs that produce light down the side of it, which makes them look invisible to predators. They also have a little lure like object that is over their head that attracts fish by blinking a light. When prey is near it, the viperfish can rotate his head and snatch the prey and eat it.
I pulled back and had the fish hooked. I knew it had to be a big fish because it was hard to reel in. After about 25 or 30 minutes the fish was almost at the doc. Then I started to pull it out of the water and that’s when I realized it was a shark. The shark was about two feet long and weighed 45 pounds.
