Common stingray (Lat. Dasyatis pastinaca). It typically inhabits sandy or muddy habitats in coastal waters shallower than 60 m (200 ft), often burying itself in sediment. It has been reported to reach a width of 1.4 m (4.6 ft) and a length of 2.5 m (8.2 ft), though a width of 45 cm (18 in) is more typical. Encountered singly or in “social” groups, the common stingray appears to segregate by sex to some degree and may be more active at night, tending to bury itself in sediment during daytime. It feeds on a wide variety of bottom-dwelling organisms, including crustaceans, cephalopods, bivalves, polychaete worms, and small bony fishes. They can’t see their prey when they hunt or when they are eating, so they use low-frequency Electroreceptors and smell detectors, which allow them to hunt and eat without the use of their eyes. Though not aggressive, the common stingray can inflict an excruciating wound with its serrated, venomous tail spine.
