Blackbar Soldierfish

Myripristis jacobus

HIGH
Family
Holocentridae
Also known as
Jacob's soldierfish
Description
A bright red reef fish with distinctive dark black bars behind the eye and operculum, large eyes adapted for low-light conditions, and translucent fins edged in dark pigment. It is nocturnal, feeding on zooplankton and small invertebrates at night while hiding in reef crevices during the day. The prominent large eyes are characteristic of the soldierfish family.
Habitat
Found throughout the Caribbean and tropical Atlantic, typically in reef crevices, caves, and overhangs from shallow water down to about 40 meters depth.
Conservation status
Least Concern
Notes
Notably, there is a parasitic isopod (likely a gnathiid or cymothoid isopod) attached to the top of the fish's head, which is a parasitic crustacean commonly found on reef fish. The right side of the image shows what appears to be a brain coral or second fish tail. Image quality is good with well-exposed subject.
