Yes, sea urchins are considered bottom feeders. They primarily graze on algae and detritus found on the ocean floor, using their specialized mouthparts to scrape food from rocks and other surfaces. Their feeding behavior plays a vital role in maintaining the health of marine ecosystems by controlling algae growth.
A sea urchin is a half-sphere. The top of the urchin is rounded like a globe but the bottom is flattish to fit on the bottom of the sea so it can walk around.

No, the long-spined sea urchin is not a filter feeder. It primarily feeds on algae and detritus found on the ocean floor using its specialized mouthparts, known as Aristotle's lantern. This species plays a significant role in controlling algal growth in its ecosystem. Filter feeders, on the other hand, extract food particles from the water column, which is not the feeding strategy of long-spined sea urchins.
A sea urchin does move, but not very frequently.
the migrate to the very bottom of the ocean way back in the deep feet
because the crab needs the sea urchin for protection and the sea urchin needs the crab for food
is whiting a bottom feeder
Ummm...it's the thing from which a sea urchin hatches?
