No, a sea urchin is not a necton. Necton refers to free-swimming aquatic animals that can actively move through the water column, such as fish and squid. Sea urchins are benthic organisms, meaning they primarily inhabit the ocean floor and do not swim freely in the water. Instead, they move slowly by using their tube feet and spines.
