据英国《每日镜报》报道，墨西哥海岸近日惊现初生连体鲸鱼尸体。
专家指出，连体鲸是灰鲸，有2个头和2条尾鳍，重近半吨重，但体长只有2米，较正常初生灰鲸短了一半，明显发育不良，相信一出生已经夭折。
These conjoined twin gray whales found washed up in a lagoon could be the first of their kind ever discovered.
The Siamese pair were spotted by a group of scientists in Mexico's Laguna Ojo de Liebre, or Scammon's Lagoon.
Scientists suspect the calves were miscarried because the carcass was only seven feet long, compared to the normal newborn gray whale size of 12 to 16 feet, reports outdoor sports website grindtv.com.
Conjoined twins have occurred in other species including fin, sei and minke whales.
But an online search, plus a search of the Natural History Museum of Los Angeles database, did not reveal any records of this type.
It is unknown whether the mother survived the birth.
It's not the first two-headed animal to be discovered recently. A piglet was born with conjoined heads and had two noses, two mouths and three eyes.
He was among a litter of 10 piglets born recently in Nanchang, the capital of eastern China's Jiangxi Province.
