Chimaera Informative Speech

Most of the members are gray in color and have some greenish tint with white bellies. This color balance enables the sharks to perfectly blend with the ocean since a prey viewing from the bottom will not see it sneaking in for a meal. The cephalofoil laterally project outwards thus giving the shark the hammerhead shape and, as a sensory organ, ability to easily notice electric field created by prey or threat from miles away. All the hammerhead sharks have excessively small mouths compared to other sharks located at the bottom of the cephalofoil with serrated triangular teeth. Hammerheads have wide-set eyes on the outer edges of the hammer adapted to give a wider and better visual range compared to other sharks.

Its flaxen eyes are usually the only part of the cuttlefish that pokes above the ocean bottom. At nightfall, the cuttlefish comes out to feed on small shrimp and fish. Two long fins haunch the sides of the striped pyjama squid body and the arms of its two tentacles have small suckers, each having a toothed horny rim. The lower side of its body is veiled in small glands that let out slime when The Striped Pyjama Squid is under attack by predators, quickly scarring off or terminating any predators from harming it by any means. It can also quickly change color to a dark purple-brown, making it easier to screen itself against corals and rocks near the bottom of the

The Great Hammerhead Shark There are many animals in the world that are endangered. One of them is the Great hammerhead shark . These sharks have flat, T-shaped heads that make them stand out from other sharks. They are long and flat in order to aid in the catching of prey. The eyes of these sharks are wide-set.

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.

For years there has been a debate on who is the top predator in the ocean. Of course the shark is an easy choice but recently in the last couple years the killer whale has emerged as a challenge towards the Great White. The Killer whale is a worthy opponent towards the great white do to its bigger size and better and smarter hunting techniques. As history has shown great whites as dominant and scary they have been to the ocean as the apex predator they have been known to be the killer whales prey. When killer whales have attacked sharks they have turned the sharks upside down.

Although all sharks are different, but no matter the size of a shark it’s always covered in denticles. Denticles fit together to equip the mako with a protective coat of armor. But just because sharks are fish it doesn’t mean that their

Rene Ismail McKenna - C 9th Grade Biology PBA American Lobster - Homarus americanus Ecosystem/Ecology of Homarus americanus Adult American lobsters tend to dwell in depths of below 50 meters. However, some can live at depths of about 750 meters.

885 wahoo’s were examined and 53% of the wahoo had food containing primarily pelagic fish and squid. The most occurring food was frigate mackerel (Auxis thazard), porcupinefish (Diodon hystrix), and the flyingfish (Cypselurus spp.) (Manooch, 1983). They have also been recorded feeding on tunas, little tunny, dolphinfish, herrings, jacks, lanternfishes, scads, and pilchards. Even though wahoo is attracted traveling closely to floating debris or plants, such as sargassum spp., their diet makes them go out into the open waters and find food there.

The sea otter has made many adaptations to its water environment. Its nostrils and small ears can close. The back feet, make the sea otter swim fast, because they are long, broad, flat, and webbed. The tail is short, thick, slightly flattened, and muscular and the front paws are short with retractable claws, with tough pads on its palms to get a good grip on prey. The sea otter propels itself underwater by moving the rear end of its body, including its tail and back feet, up and down.

The eggs are all different according to the species. Some have round planktonic eggs, unknown eggs and also large, long eggs. The process of fertilization is a mystery due to its habitat being so deep and below sea level, but it is believed that the female release her eggs into the water and waits for a male to fertilize it. The process then continues by the eggs floating to the surface until the day they hatch. Osmoregulation involves the regulation of osmotic pressure within the internal environment of an organism.

The mako shark 's skin is smooth which helps the shark to swim as fast as possible. Mako sharks are very diverse in where they live. For example,

All About the Grouper The grouper is basically a kind of fish under the family of sea creatures that include the sea bass. They have a sort of scary looking build, which makes them popular for use by artists in some TV cartoon series. So, what does the grouper exactly look like? Picture this: a fat body, a huge mouth, and an overall aura that will basically tell everybody who will see them that they are not worth this grouper 's time and attention.

Belugas when they die fall through the same ocean layers and give nutrients and food in all the

This beautiful looking fish packs a punch: The fish has venomous spines that deliver an extreme pain that can last for days. In extreme cases, the venom can even cause paralysis. The LIonfish is an apex predator on the reefs using its fins to coral small fish and anything it can fit into it’s mouth into a corner before it strikes quickly swallowing it whole. The lionfish feeds on an array of over 50 species including ecologically and economically important species. ("Lionfish Biology Fact

Sailfish get their names from the large sail like fins they carry on their back. These fins are usually taller than the body of the fish itself. They also have a second, smaller dorsal fin and two sharp rudder like fins on their bellies for sharp cutting turns in the water. The fins are usually a darker color to intimidate other predators. The more commonly known Atlantic sailfish are 6 feet long but have been known to go up to
