The Frog seashell is a thicker, heavier shell. The smaller ones have
a peculiar glossy finish that resembles the skin on certain frogs.
These have small knobby spines and also resemble the warty skin
frogs. They are related to the Triton shell family. Generally they are
found in warm tropical waters around coral reefs and rocks.
The Bursa Spinosa seashell is from the Bursidae family.
