Sharks are extremely unique and an essential part of the ocean and sea ecosystem. There are over five hundred different types of sharks living in the world. Sharks can be divided into two main groups, large and small.
Evolution Domain: Eukarya Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Perciformes Family: Centrarchidae Genus: Micropterus Species: salmoides The normal weight of the largemouth is one kilogram. On the other hand, certain largemouth basses have gotten to be over ten kilograms in weight. The males usually does not get longer than 40 center meters, while the females can get to be 56 center meters long. The largemouth bass has a big, but somewhat slanted mouth.

Once an alligator “closes it jaw on a limb the force is so great that getting the alligator to open its mouth again is virtually impossible “ (Strawn 43 ). The adult reptile “has small legs and webbed feet that are designed for “propulsion and maneuvering but not for attack” (Visiting the Heart of Alligator Country) However the “swipe of a gators tail can knock a person into the water when it is most agile, powerful and destructful” (Strawn 43). Not to men-tion an alligators tail is what gives it it’s speed of up to approximately 20 miles per hour in water but then becomes a slower awkward giant on land. This sounds to be very similar to that of some of the dinosaurs from many years
2. THERE ARE NO CONSISTENT TRENDS IN EVOLUTION: In the evolution of sharks, we clearly see that there are no consistent trends in their evolution from the beginning of their existence, they are a species that are always changing or evolving as mentioned in the previous example. This is why we see the diverse amount of species of the shark family all over through the ages both prehistoric and present. And can clearly see the branching out of the species from is simplest form to various other forms, the branching of the shark family can be seen
Sea otters are omnivores as they do eat kelp and other sea-going plants. Regardless of this however, most sea otter people have an essentially flesh eating diet with sea otters known to eat more than 40 unique types of marine creatures. The sea otter chiefly chases ocean urchins, mollusks, crabs, snails and little fish in the water.

(n.d.)). The barbled dragonfish also has a size range of growing between 4 and 6 inches (Deep Sea Dragonfish. (n.d.)). They inhabit tropical ocean regions (Deep Sea Dragonfish.
This could happen because some fish like the parrotfish envelope themselves in their own mucus to not 3. What Do Sea Sponges Have? Sea sponges are a very unusual animal to the lacking of many necessities in their body. They don 't have a head, mouth, bones, eyes, legs/feelers, lungs, a brain, and they can still properly function and are still a living organism. This is also pretty unusual for marine animals to have that many things in their body because many of them can 't live without that many body parts.
The mouth is very large with a beak-like snout (figure 2). They have jagged teeth. The maximum length caught was approximately 250 centimeters but range from 85-105 centimeters with a maximum weight of 83 kilograms (Luna, n.d.). It does not have any gill rakers. Pectoral fins (2) on each side of its body is present.
The back flippers is like a paddle shape. Its ridged carapace and their large flippers do make the leatherback turtle is uniquely equipped or prepared for long distance hunting for food. The Female leatherbacks took 2-3 years to re - migrate to their nesting sites. The females nest around several times within a nesting season, during the nesting season usually after 8-12 day intervals they lay approximately 100 eggs. After around 2 months, the leatherback hatchlings come out or emerge from the nest and have a white striping along the ridges on the back and also on the margins of the
