The symbiotic relationship is commensalism because the tiny fish gets a place to hide while the sea urchin is unaffected.
The purple sea urchin (Strongylocentrotus purpuratus) often forms a symbiotic relationship with various species of algae, particularly kelp. These sea urchins graze on kelp and other algae, which helps control algal growth and maintains the health of marine ecosystems. In return, the presence of healthy kelp forests provides habitat and food sources for many marine organisms, creating a balanced ecosystem. This relationship is crucial for the ecological stability of coastal environments.
Yes, sea otters have a mutualistic relationship with kelp. Sea otters control sea urchin populations by feeding on them, preventing overgrazing on kelp forests. In return, kelp provides a habitat for sea otters and helps stabilize the marine ecosystem.
The relationship between them is the sea.
no
The classification of a Sea Urchin is Echinoidea

sea urchin

Ummm...it's the thing from which a sea urchin hatches?
parasitism
