Deep-sea Angler Bufoceratias wedli

Living in the deep sea, this small, dark-colored anglerfish has a round body, delicate fins, and a luminescent lure at the end of a long rod called an illicium. A second, much smaller rod on the head is often hidden from view. The deep-sea angler has a weak skeleton and small muscles that make it relatively light and able to float more easily. It has no need to swim much as it lures its prey within reach. Female deep-sea anglers have been caught undamaged by research submarines using a piece of equipment called a slurp gun that sucks animals into a container. The fish have then been photographed alive. Male deep-sea anglers have not yet been seen but are likely to be tiny and free-living.
