- There are over 3,000 known species of sea hares that vary greatly in size from 0.25 to 12 inches. They are in the genus Alypsia.
- Sea hares have a tentacle with a mouth at the end of a short snout to bite, rasp, or suck their food. They are classified as mollusks.
- When threatened, sea hares release clouds of ink to blind attackers. The students observed the sea hares they collected ink all over their gloves and climb the sides of the glass tank to reach the surface for oxygen.
2. Facts There are more than 3,000 known species. They can grow as small as 0.25 inches or as large as 12 inches. It’s in the Alpysia Genesis. Alyssa has proof that it squirted purple jelly on her glove. Also, other people have seen the purple jelly.
3. Mouth The mouth usually opens at the end of a short snout with a tentacle. They bite, rasp, or suck in their food.
4. Placements Kingdom – Animalia(made of cells, move, find food, can’t use sunlight to make sugar) Phylum – Mollusca(no bones, smushy unless you have a shell, snails, squid, octopus, clams) Class – Gastropoda(snails and such) Genus - Alypia
6. What we observed The sea hare’s inked all over our gloves. When we put the hare’s in the water they expanded and little spikes came out of them. They went to the surface of the water to get oxygen. They were climbing all over the sides of the glass.
8. Standards Met 8 standards met in this project. How Science works – the scientific process. Here are the steps we did – went to the ocean, caught weird things, held one, they inked, we brought them back and put them in a tank, we watched them, we did research, and we put together our findings. We argued our point with others – people were saying it was a sea slug but we were telling them it was a sea hare.
9. Standards Met Reproduction is essential for the survival species – They eat a lot and lay more eggs. Plants and animals need each other to survive – Sea hares need to eat plants to survive. Human activities and natural events can have major impacts on the environment – the sea hares are washing up on shore more than usual because of the fertilizer that is in the plants goes in the lakes because of rainfall and washes into the ocean.
10. Standards Met Living things share similar basic needs – they need oxygen sunlight and water to live just like we do. Living things get energy many different ways – Sunlight, oxygen, when we put them in the tank the water was not rippling like the ocean so the sea hares climbed up the side of the tank and lifted their heads out and got oxygen.
