Rare conjoined gray whale twins found in Mexico

MEXICO CITY  - The Mexican government says fishermen found two rare conjoined gray whale calves that died shortly after being born.

Bermudez said Wednesday they were linked at the waist, with two full heads and tail fins.

Bermudez is a marine biologist with the National Natural Protected Areas Commission, or CONANP. He said scientists are collecting skin, muscle and baleen samples to study the creatures.

Every year more than 20,000 gray whales swim to Mexico from Alaska to mate and give birth.
