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. -
