Species overview
About the Graybar Grunt
Adults show about five or six dark bars on the upper sides of a silver-white body. The tail is forked, and the mouth sits low on the head.
It uses sandy, rubble and rocky habitats. Juveniles show lengthwise stripes that gradually give way to bars, making growth stage important when comparing fish.

Habitat & range
Pacific rocky reefs and nearby coastal marine habitats. Check the linked species reference for its wider range.
Local observations
Recorded at Cabo Blanco.
When to observe
Visibility depends on water clarity, currents, depth and conditions. No fixed local viewing or migration season is assigned.
Conservation & care
Observe with a qualified guide. Do not feed, chase or handle fish. Keep fins off the reef and take all litter home.
Threats & pressures
Habitat damage and degraded water quality are pressures to prevent in coastal fish habitats. This profile does not quantify a local decline.
Observation activity
Draw one lengthwise stripe and one vertical bar. Match each to a young or adult photograph.
