How To Keep Sea Urchin

Sea urchins can be used as fish bait, but if you use them improperly, they will die. The following method is suitable for people who live in the wild on the beach.

In general, sea urchins are divided into two types: sand and rock. The rock type is relatively easy to find, and the sand type is relatively difficult to find because it is hidden in the sand. If you want to catch a lot of sea urchins at once, you can use a net with a diameter of about 50 cm, sink directly into the water along the beach, flush out some sand sea urchins; or you can use your hands to dig the sand in a certain place where there are more sea urchins and then pour it into the water. In this way, every time you can catch dozens of sea urchins one time. If you plan to leave for several days, try to take out more than 30 sea urchins at one time so that they can survive for several days without food.

After catching the sea urchin, put it in a large bucket filled with seawater and then put it in a cool place such as an open air corridor.

I'm writing for advice on how to keep sea urchins as pets. I've been keeping them for about a year and a half, and have mostly figured out what they like; but there are still some aspects of their life and behavior that leave me puzzled.
