This Cloudy Grouper (Epinepheluserythrurus) is in a fight with a second cloudy grouper about who gets the Dinner. Dinner is a streaked spinefoot (Siganus javus), also known as the Java rabbitfish.
The Grouper reaches a length of: 45 cm
Streaked Spinefoot reaches a length of: 40 cm.
Venom of the streaked spinefoot
has grooves in the spines of the dorsal, anal and pelvic fins which contain venom glands. The wound caused by these spines may be relatively painful to humans, but is usually not dangerous. The spines are used in self-defense. In a study of the venom of a congener it was found that rabbitfish venom was similar to the venom of stonefishes.
Seems like the Cloudy Grouper isn’t affected by it?!
