The enormously elongated fin rays are typical of the tripod fishes. These fishes live at depths of between 475-5600m in tropical and temperate oceans. The exact function of the rays is unknown, but observations suggest that the lower rays act as a tripod when the fish 'stands' on the muddy seabed (giving the fish its name). They are also thought to be touch-sensitive, enabling the fish to search for food. |
