Sea urchin
Sea urchins or urchins () are typically spiny, globular animals, echinoderms in the class Echinoidea. About 950 species live on the seabed, inhabiting all oceans and depth zones from the intertidal to . Their tests (hard shells) are round and spiny, typically from across. Sea urchins move slowly, crawling with their tube feet, and sometimes pushing themselves with their spines. They feed primarily on algae but also eat slow-moving or sessile animals. Their predators include sea otters, starfish, wolf eels, and triggerfish.
Turtling (hunting)
While there are several turtle species at risk, the loggerhead sea turtle ("Caretta caretta"), which made the IUCU endangered animals list in 1996, and the leatherback sea turtle ("Dermochelys coriacea") which has been experiencing a decline in numbers, are both still being hunted or killed due to human impact. Another turtle species that can be hunted (not commercially) while considered as special concern at the Canadian and Ontarian level is the snapping turtle ("Chelydra serpentin"). Hawksbill sea turtles have been hunted for their shells primarily to make jewelry. Tourists will often buy items without being informed of the source of the material. Green sea turtles eggs are poached and eaten in many countries; this is also a tourist attraction and taking sea turtle shots, consuming raw turtle egg with whiskey or beer is popular in places like Costa Rica.
