There are lots of creatures you can find in tide pools along the shoreline and beside the rocks in the water. Here are some of the things you can find along the shore. Of course you can find the starfish. There are three different kinds of tide pool starfish. One is a grey and white looking starfish. When you put them in the water, you can watch them move very fast. You can have starfish races. There are also red pokey starfish.
They are small and they do not move very much but they are prettier. The last kind of starfish is a white one with 8-inch skinny arms and they also move very fast.
There are also sea cucumbers. They look like a brownish black long thick tube. And my favorite one is nudibranchs. They look like a squishy blob with yellow and black rings. You can find them along the rocky shores. They like to go along rocks. They are basically a snail out of their shell but a little different. There is a picture below.
For some reason the nudibranchs release purple ink. I’m not sure why but it is a very pretty color. Do you know why they release this ink? We do not have a book on board that tells us about them. If you find out why, please reply to my post and let us all know.
The next picture is of my brother holding some nudibranchs and behind my brother there is a tide pool full of starfish. The very first tide pool is of the sea cucumbers.
In every tide pool there also is baby fish. They are fun to watch but are hard to catch. I’ve found baby squirrel fish and baby angelfish. We made a lake for them to swim around in. Here is a picture of the squirrelfish.
lI googled nudibranchs purple and this is what I got back.
Most of the 37 or so world species of sea hares Aplysia release a purplish-coloured ink when disturbed. Additionally, some species release a white “opaline” secretion, also thought to be used for defense. Species eating red seaweeds also have a variety of secondary metabolites in their skins and digestive glands that may be defensive. This section starts with a review article that provides a comprehensive overview of defenses in sea hares, and should be a “must-read” for anyone interested in the subject. After this the Research Studies are presented chronologically.
There is a lot more in the article. Let me know if you want me to send it to you.
