Sargocentron is a genus of squirrelfish found in tropical parts of the Indian, Pacific and Atlantic Oceans, with the greatest species diversity near reefs in the Indo-Pacific. Being largely or entirely nocturnal, they have relatively large eyes. Red and silvery colours dominate. The preopercle spines are venomous and can give painful wounds. Most have a maximum length of 15–25 cm (6–10 in), but S. iota barely reaches 8 cm (3 in), and S. spiniferum can reach more than 50 cm (20 in).
Sargocentron caudimaculatum, the silverspot squirrelfish or whitetail squirrelfish, is a reef-associated member of the family Holocentridae. It is native to the Indian and Pacific Oceans from East Africa to Japan and northern Australia and as far east as the Marshall Islands. It lives near reefs, but can also be found in lagoons and drop-offs at depths between 2 and 40 metres. It is a nocturnal predator, feeding primarily on crabs and shrimps. It can reach sizes of up to 25.0 centimetres (9.8 in) TL. Although it is caught commercially and can be found in the aquarium trade, there are no known major threats to this species.
