Coelacanths, A fossil fish that predates dinosaurs and was thought to have gone extinct has been found alive in the West Indian Ocean off the coast of Madagascar. It was accidentally rediscovered by a group of South African shark hunters. Demand for shark fins and oil has led fishers in southwestern Madagascar to set gill-nets in deeper waters. They are finding and possibly harming previously-unknown populations of these West Indian Ocean Coelacanths.
Sea cucumbers are echinoderms—like starfish and sea urchins. There are some 1,250 known species, and many of these animals are indeed shaped like soft-bodied cucumbers. All sea cucumbers are ocean dwellers, though some inhabit the shallows and others live in the deep ocean. They live on or near the ocean floor—sometimes partially buried beneath it.
