The tripod fish or tripod spiderfish, Bathypterois grallator, is a deep-sea benthic fish in the family Ipnopidae found at lower latitudes. It is now relatively well known from photographs and submersible observations, and seems to prefer to perch on the ooze using much elongated fin rays in the tail and two pelvic fins to stand, facing upstream with the pectoral fins turned forward so the outthrust projecting fin rays resemble multiple antennae, and are indeed used as tactile organs. B. grallator is hermaphroditic. At least 18 species are placed in the genus Bathypterois, several of which have similar appearance and behavior to B. grallator. B. grallator is the largest member of its genus, commonly exceeding a standard length of 30 cm (12 in) and reaching up to 43.4 cm (17.1 in). Bathypterois grallator has been found relatively widely in the Atlantic, Pacific, and Indian oceans from 40°N to 40°S. It is a wide-ranging eurybathic fish found from 878 to 4,720 m (2,881 to 15,486 ft) deep. Feeds on nektonic copepods and other small planktonic crustaceans. We do not know enough to say for certain if this fish is preyed on by any other animals.
