anemones fold inwards to hold in moisture

Answer 2

Your teacher probably wants to test your ability to draw conclusions and make inferences based on existing knowledge of these organisms.

Some of the answers are less obvious than others and I had to think about them a bit, too. That's why I decided to help. I hope you'll think about why the answers fit the questions so I don't have to feel like I gave you TOO much help.

This is what I came up with:

barnacles - closes the door

kelp - holdfasts to secure themselves to rocks

hermit crab - shell to hide inside

mussels - stores water then slowly releases it

grunt sculpin - pants to force water over gills

starfish - move to shady area

anemones - fold inward to hold in moisture

For example you probably know that hermit crabs live in the shells of mollusks and that some of the animals on your list don't have gills and some are sessile and others are motile. Knowing these things makes it possible for you to infer the answers.
