Asthenosoma varium is a large urchin (25 cm) with flattened, flexible test (the plates are articulated rather than fused). Very mobile, short spines, arranged in rectangular areas, separated by spineless areas. Spines have a blue swelling close to the tip, filled with venom.Living in bay, lagoon, external reef; on sandy or rubble bottoms. The flexible test allows, changing the shape, to enter very narrow crevices. The swollen shape of the spines and the flexible test are unique features. \nAsthenosoma varium sting can be very painful, a strong local pain due to venom injection can last for hours.\nThis specimen was encountered in a very shallow tunnel in the Triton Bay, Indonesia \n3°54'51.39 S 134°7'24.81 E at 2m depth
