DISTRIBUTION/HABITAT: C. strigosus is found in the Central Pacific in coral-rich areas of deep lagoon and seaward reefs.

DIET IN THE WILD: Herbivore, grazing algae and detritus using its comb-like teeth. Their diet may contain high concentrations of the dinoflagellate that produces ciguatera toxin, and so bristletooths and their predators are known to sometimes concentrate sufficient toxin to cause illness in humans.
