Description and biology
The Hawaiian silverside has two dorsal fins and a prominent lateral stripe, which sets them apart from other baitfish.[1] They can grow up to three and a half inches. They are greenish gray on the back and have a silvery stripe topped by a blue-green line running the length of the body.[1] They disperse to feed on plankton at the surface at night.[3]
Distribution and habitat
Atherinomorus insularum are endemic to Hawaii. They are a common schooling fish often found near the surface in tidepools and coastal waters.[1]
Human use and cultural significance
In ancient Hawaii, these fish were sometimes used to rub the face of a human sacrificial victim to make it shine like the eyes of a maneater shark.[3]
