What does the spiacle do?

Answer 1

The "spiacle" is a term that typically refers to a specialized structure in certain marine organisms, such as some species of fish and echinoderms, that serves as a small opening or tube for respiration or water intake. In the case of certain fish, it can help facilitate water flow over the gills when the fish is at rest or on the substrate. This adaptation allows these animals to efficiently extract oxygen from their environment while minimizing movement.
