One of my favorite California fishes is the giant kelpfish (Heterostichus rostratus). Giant kelpfish are camouflage masters, blending into the brown and green kelp blades perfectly. Many times I have found myself hovering over a clump of kelp for a few minutes, not aware of a giant kelpfish only a foot or two away from me until it began to swim. As long as they remain stationary in the kelp, swaying back and forth with the kelp, they are nearly invisible. Cool fish!
A giant kelpfish swims over Southern sea palms and a kelp-covered reef, mimicing the color and pattern of the kelp leaves perfectly, camoflage.
