What makes this animal special? These guys are masters of camouflage, they're able to blend in with their surroundings from rocky sea floors and corals to patches of seaweed in a matter of seconds.

Plankton

Plankton are important because almost every ocean animal depends on them as a source of food. Some plankton like Phytoplankton need to be near the surface of the water, where light is, to photosynthesize. They have unique adaptions like air and oil pockets, to keep them floating near the top.

A copepod, a type of zooplankton

Then there are Zooplankton, which are different from phytoplankton. Phytoplankton photosynthesize to eat. Zooplankton on the other hand, use the phytoplankton as a food source. For zooplankton to stay floating near the top where their food source is they have special adaptions also. Zooplankton have spikes and projections to keep it from sinking to quickly.

Scientific Name: Chrysaora fuscescens

Habitat: These guys live off the west coast of the U.S., as far south as Mexico and as far north as British Colombia. There have even been sightings around Japan.

Reproduction: Sea Nettles reproduce from eggs and spread by polyps.

Predator/Prey: The Sea Nettle eats plankton, zooplankton, crustaceans, snails, small fish, and sometimes other jellyfish. Sea Turtles, and Spiny Dogfish eat these jellies.

5 Interesting Facts: 

1. Jellyfish ar 90% water
2. Pacific Sea Nettles can have tentacles as long as 16 feet
3. Their Bell can be up to 30 in wide
4.  They have light sensing organs that they use to move to deeper or more sunlit water.
5. Sea Nettles spread their toxic tentacles out like a net to catch food.

Underwater Camera

   Underwater Cameras are specifically designed to take pictures and photographs in underwater conditions. These cameras are used by all kinds of people from amateurs, and tourists taking pictures of family and friends to divers and professionals like Underwater Filmmakers documenting marine life and their habitats.

Hammerheads tend to live

Reproduction: Reproduce every year with the female giving live births. After the babies are born, the parents do not protect or take care of them.

Predator/prey: These sharks are predictors and eat almost anything from fish, squid crustaceans and on occasion, other sharks. However stingrays are a favorite for them.

Endangered?Why?: yes, Shark fins are sometimes served and eaten world wide. When fisherman catch the shark and cut off their fins, the shark is sent back to the ocean without it's fins and eventually dies.

Boat Design

The design we chose was a:

• Styrofoam egg carton top, cut to our needs
• square black fabric kept up by a popsicle stick
• 2 rudders made from left over styrofoam
• 3 keels made from 3 popsicle sticks

Our fastest test time was 2.30 seconds, If we had to change anything we would have fixed the keels on the bottom. The boat went a little crooked when we tested it.
