Marine conservationists
and government scientists are seeking clues to the mystery of how a 44-foot
whale carcass ended up on the bow of a cruise liner, where it was discovered as
the ship approached New York City's Port of Brooklyn over the weekend.
A necropsy, the animal equivalent of an autopsy, identified the deceased
marine mammal as a mature female sei whale,
an endangered species typically found in deep waters far from land, the
Atlantic Marine Conservation Society said on Wednesday 8 May.
One key question is whether the whale's death came before or after its
contact with the vessel, according to the non-profit organization, based in
Hampton Bays, New York.
An online statement posted by the society, whose team conducted the
necropsy on Tuesday, said the exam revealed evidence of tissue trauma along
whale's right shoulder blade region, and a right flipper fracture. The creature's gastrointestinal tract was
full of food, it said. Most of the whale's organs were sampled, along with
tissue and bone, for toxicology and pathology analysis, according to the
society.
"The tissue and bone samples collected will help biologists determine if the vessel interaction occurred pre or post mortem," the group said in its statement.

It said the U.S. National Oceanic and Atmospheric Administration's law
enforcement office was also investigating the incident. The whale's corpse was carried into port on Saturday. The
conservation society said the whale was then towed to shore at Sandy Hook, New
Jersey, to conduct the necropsy.
Sei whales, members of the baleen branch of cetaceans that filter-feed
on plankton and krill, take their name from the Norwegian word for pollock, a
fish they often run with at sea. They are known as exceptionally fast swimmers,
capable of reaching speeds of more than 34 miles per hour (55kph), according to
NOAA. They dwell mostly in subtropical, temperate and subpolar seas around the
world, primarily the Atlantic, Indian and Pacific oceans. In summer, they are
commonly found in the Gulf of Maine and on Georges Bank and Stellwagen Bank in
the western North Atlantic.
