Biology
The redfingers is quite common in tidal pools, although it has been seen in depths up to 120 metres on rocky seaflloors. It feeds on small crabs, molluscs, worms, and other small invertebrates. The juveniles often seek shelter in floating objects.
Curiosities
The adults have an unusual characteristic: the lower rays of the pectoral fin are narrow and elongated. These rays, in the posterior region, are free and function as appendages. They serve to maintain their balance when the fish is resting, and to detect food.
