double-headed shark

When a fisherman caught a new bull shark recently off the coast of Florida, USA, he was surprised to discover that one of the fetuses still alive inside the mother shark's belly

A pair of sharks, both of which have two heads, are found in a personal collection. One of the above two children was in the vessel since it was discovered in 1934 off the coast

An American fisherman saw a shark's fetus in both ends while operating a shark's abdomen, and Cubans saw a two-headed turtle on the river bank.
