Hairy Frogfish | Antennarius striatus

This is a large male hairy frogfish (Antennarius striatus) opening his mouth. Frogfishes exhibit this type of yawning behavior relatively frequently. In this image, the frogfish's illicium (rod) and esca (lure) are folded back and tucked away on top of the fish's head, comprising the front-most of three dorsal fins. The white hair-like protrusions on the fish's body are small amphipods known as skeleton shrimp (Caprellidae). This photograph was taken three days prior to this fish spawning with a smaller female.
