Many juvenile wrasses are cryptically colored to avoid predation while others find protection among the tentacles of sea anemones. Nearly all adult wrasses bury themselves in sand at night to avoid predators. A few species seek out reef crevices and produce a foul-smelling mucous bag to deter predators while sleeping. Razorfishes (Hemipteronotus, Xyrichtys) also use the sand for protection during the day by diving into the bottom. Razorfishes are apparently quite agile in this environment, sometimes resurfacing several meters from the point of entry.
