Micromelo undata (Brugière, 1792)
These animals crawl on algae-covered rocks in shallow water. Their beautiful
blue-green mantles, which almost glow in the sunlight, are adorned with white
spots and yellowish margins. The shell, attractively patterned with black spiral
lines intersected by wavy transverse ones, is too small to hold the animal's
entire body. This species feeds on small, colorful bristle worms of the family
Cirratulidae, whose toxin they incorporate for their own defense. The species
name means "wavy." Micromelo guamensis is considered a synonym by most
researches. It attains about 1/2 in. and occurs in all warm seas.
