Plankton importance

Plankton are important to our food chain because they are the producers. So if we did not have them, than we would not have any of the bigger fish because they would not have any food. Plankton travel through currents and waves. They need sunlight to survive. An example of a phytoplankton would be a diatom. An example of a zooplankton would be a jellyfish. They are diffent in that the diatom is the producer and the jellyfish is the consumer.

A plankton net

Marine biologist use a plankton net to easily catch the plankton to study. They use this net to get plenty of specimens of these animals.

Sponges

Sponges

Phylum Porifera 

They can live anywhere from warm water to very cold water on the ocean floor.

They reproduce both asexually and sexually.

The poors in the sponge take in the water and filter it to get the nutrients in the water, they are eaten by turtles, snails, and other fish.

There are 15,000 different species of sponges.

They can live up to 23000 years.

Larva can live in them until they grow bigger.

Sponges are used also as cleaning tools.

Many animals use sponges as their homes.

sail boat

We chose this design because it was not heavy and could float. We also put 2 sticks in the middle so that the marbles would be evenly distributed. Our average time was 3.23. We could have changed the sail part because maybe it would have made it faster. But over all I think it did well.

Oceanographer

Oceanographers take photos of things in the ocean and let everyone see what is down in the ocean. These people are important because they give everyone else a chance to see what is in the ocean that do not have the oppurtunity to do so. They study ice caps. They also can study on things like the coral reefs. They like to take pictures of things that have a lot of importance because they can be payed a lot of money for each picture. They can use robotic things to help get into places that can't be reached also. 

Tiger shark

Scientific name: Galeocerdo cuvier
These sharks are found in deep water but also in shallow water. Lately they have been migrating towards the shore. They like to eat seals and are usually never hunted but sometimes killed by killer whales or humans. Tiger sharks can eat anything which helps them a lot. They also like to swim alone. Tiger sharks are very aggressive and are known as the "garbage can of the sea". Three interesting facts would be that they can be up to 16ft long. Can weigh up to 3,360 lbs. females mate once every three years. These sharks are not endangered because they are at the top of the food chain.
