Found almost everywhere by divers, this fish lives either in schools or alone. It is a voracious eater that feeds constantly. It is also a very successful "cleaner fish", and a single Senorita may be surrounded by dozens of fishes waiting to be cleaned of parasites. Divers report them teaming up to clean a large sea bass or Mola. This fish does not reverse sex as most wrasses do. When disturbed, it burrows in the bottom sediment. It also sleeps there with its head protruding from the sand. Edibility is poor. Range is Northern California to Central Baja.
