Quite a few cartilaginous fishes (Chondrichtyes, which includes the ratfishes and elasmobranchs, i.e., sharks, rays, skates, etc.) often have a horny (collagen) egg capsule, inside of which one or more embryos develop. In this case, Ivan's gf is holding a horn shark egg capsule, and they could see the embryo inside. This "spiral-flanged" egg case shape apparently allows it to be secured within crevices. -Doug Eernisse Horn Shark Egg, Shark Egg, Horn Shark, Zebra Shark, Sea Life Creatures, Mermaid Purse, Ocean Science, Life Aquatic, Ocean Fishing
