Its weight does not exceed 500 g. The muzzle is pointed, and the thorax is wide with a square outline. It has no tongue or teeth-it seeks food in the muddy bottom, turning over the silt with its front paws. Its external nasal openings are located at the end of its muzzle. Small eyes, widely spaced, and pointing upward, are placed on the edge of its head. It has a large mouth, ending in a pair of tentacles. Its limbs are thick and heavily muscled, ending in thin fingers with thread-like outgrowths (stellate organs) that facilitate spatial orientation and help sense invertebrates buried in the silt. The fingers are clasped with an amniotic membrane, allowing swimming.
