@easyjourneybali: Sea urchins are spiny, globe-shaped echinoderms that can be found in the waters surrounding Nusa Penida, an island located southeast of Bali, Indonesia. These creatures are a common sight in the shallow coral reefs around the island. Nusa Penida is home to several species of sea urchins, including the black sea urchin (Diadema setosum) and the long-spined sea urchin (Echinothrix calamaris). The black sea urchin is characterized by its black spines and its ability to climb over rocky surfaces using its spines as legs. The long-spined sea urchin, as its name suggests, has longer spines that are a yellowish-brown color. Sea urchins play an important role in the marine ecosystem as they help control the growth of algae by grazing on it. However, their spines can be dangerous to humans, as stepping on them can result in painful injuries. Therefore, it is important to exercise caution when swimming or diving in areas where sea urchins are present. In addition to their ecological importance, sea urchins are also harvested for their roe, which is considered a delicacy in many countries, including Japan and Italy. In Nusa Penida, local fishermen may collect sea urchins for their roe, but it is important to ensure that harvesting is done sustainably and without causing harm to the fragile marine ecosystem. #nusapenida #bali #urchins #fyp
