Introduction to Marine Biology
| Did you know 2/3's of the earth's surface is covered by salt water? | ||||
| MOLLUSCS This is how it probably looks when you find it on the beach. | ||||
| This is how it looks when it is alive in the water! That's right! There is an animal in there! Have you ever eaten clam strips? They may look gross here but they sure are tasty! | ||||
| Here is another tasty animal you or your parents may have eaten before too. It is called a scallop. See the beautiful ridges on it and the little "wings" at the base of the shell? This is a good way to identify a scallop from other shells. | ||||
| This is called a cockle shell. These are all over the beaches of the East coast. They sort of look like a scallop but they have no "wings" at the base like a scallop. They are also not as flat as a scallop. | ||||
| Have you ever held one of these to your ear? This is a conch shell. | ||||
| Arthropods Here is one example of a crab. There are many colors, sizes and shapes of crabs. Other animals in this group are lobster and shrimp! | ||||
| Largest coral reef in the world is called The Great Barrier reef. It is found in Australia and is over half the size of Texas! Corals may look like big colorful rock but are actually thousands of tiny animals with a mouth and a ring of tentacles. The hard substance is their skeleton. After they die, their skeleton stays there and another polyp grows on top of the old producing a beautiful coral! | ||||
| This is a sea anemone. Who remembers what kind of fish doesn't get stung by this poisonous animal? | ||||
| Jellyfish!! They are really NOT a fish at all and so now are being named, Jellies. They are in every ocean in the world. They have no brains, blood or nervous system. They have tentacles that can sting! | ||||
| Tropical fish such as the butterfly fish add to the beauty of the coral reef. | ||||
| This Lionfish sure is pretty, but watch out! Those big spines are a warning that it is a very dangerous fish to touch! | ||||
| This is a beautiful starfish. Did you know that starfish can be all sorts of colors and sizes? They can also have more than five arms! They can have up to 18! If one falls off, they can just grow a new one! | ||||
| Sharks are amazing fish that often get a bad reputation. They help the ocean by keeping smaller fish populations under control. They have no bones and can have multiple rows of teeth! | ||||
| There are six types of sea turtles in our oceans. A couple of the most famous are the green and the hawksbill turtles. | ||||
| Octopus -Eight arms -Squirts ink for defense -Siphon water to swim -Live in dens -Can be up to 20 feet across from tip to tip! | ||||
| Giant Squid! Did you know that a giant squid's eye can be as big as your dinner plate!!! The largest squid ever found was 59 feet and weighed 2000 pounds! They have 8 arms and 2 large tentacles! | ||||
| Dolphins are marine mammals too! Have you ever seen a dolphin come up for air? | ||||
