Frog Seashells

Family: Bursidae. The common name Frog Shell comes from the knobby sculpture of most species, which resembles the warty skin of some frogs. This small family group of 30 species lives in tropical or warm seas and features a thick and heavy shell. Frog shells are close relatives of Tritons and have some similar characteristics. The female is usually larger than the male. Most of the species live under coral and consume marine worms. Their egg capsules attach to rock or coral. The deep-water species have sharp, blade-like ridges while the shallow water dwellers have dull, knob-like ridges. Frog shells are carnivores and feed on marine worms and bivalves. Interesting Facts: In its natural state, the beautiful and intricate design of the large Frog Shell is completely covered with a very heavy calceous growth to provide camouflage protection from other marine predators.
