Off the shore of Spain, a fin whale with a malformed vertebrae was recently
seen having trouble swimming. Experts believe that a vessel impact caused
its spine to break.
A fin whale with a badly misaligned spine was recently captured on camera
trying to swim off the shore of Spain in the Mediterranean. The gentle
behemoth will probably slowly starve as a result of this severe case of
scoliosis, which experts believe was brought on by a vessel hit.
The boat's crew discovered the wounded fin whale (Balaenoptera physalus) on
March 4 off the coast of Cullera, close to Valencia. It measured 56 feet (17
meters) in length. , a lot of the time. Those who have been a lot of the

not trapped; instead, it had "scoliosis of unknown origin," Oceanographic

wrote on Facebook.
The wounded animal's back was too deformed for the satellite tag to adhere
when the researchers tried to mount a monitoring device on it. The fin whale
quietly moved away from the coast and into deeper waters after "a few hours
of attention," according to officials of Oceanographic Valencia.
Live Science was informed by experts that the whale's scoliosis was likely
brought on by a vessel impact that fractured the whale's back.
The head scientist of the Pacific Whale Foundation in Hawaii, Jens Currie, explained in an email to Live Science that the
word "scoliosis" merely refers to an aberrant lateral curvature of the
spine. Scoliosis can have many different causes, but blunt force injuries is
by far the most prevalent.
Erich Hoyt, a research fellow at Whale and Dolphin
Conservation (WDC) in the U.K., and Simone Panigada,
vice-president of the Tethys Research Institute in Italy, concurred that it
is probable that the whale "was recently struck by a vessel," as Currie put
it. However, the experts pointed out that it's challenging to pinpoint
precisely what occurred.
Scoliosis can occur in young whales or be present at birth in big whales.
However, Currie noted that juvenile whales with scoliosis almost never
survive to maturity.
Fin whales, blue whales (Balaenoptera musculus), humpback whales (Megaptera
novaeangliae), and other species of baleen whales forage by lunging through
vast shoals of krill, or microscopic crustaceans. They do this by quickly
moving through the water with the help of their huge tails, or flukes.
However, the video shows that the wounded whale is unable to do this, which
suggests that it is likely famished.
The whale is already very skinny and starting to appear unwell, as we can
see from the footage, according to Currie. It's extremely improbable that it
will endure. Baleen whales can go for months without eating, so wounds like
this could result in a "slow and painful death," the expert continued.
The connection between cetacean scoliosis and vessel collisions is not new.
According to The Guardian, a humpback whale named Moon traveled more than
3,100 miles (5,000 kilometers) using only her fins before being discovered
in Hawaii in December 2022 with a fractured back. Another
fin whale with scoliosis was discovered by Panigada the previous year close
to Barcelona, though the spine deformity was less serious.
But most whales don't make it through a run-in with a boat. According to
the Italian non-governmental group Friend of the Sea, due
to a more than 300% rise in worldwide maritime traffic since 1992,
approximately 20,000 whales are thought to be killed annually by vessel
collisions. However, Hoyt noted that it is difficult to monitor this since
most killed whales are never discovered and attacks are frequently
ignored.
Whales are subjected to a lot of noise from commerce in addition to vessel
collisions, which can impair their ability to navigate, feed, and
communicate. According to Currie, "I would argue that [ship traffic] is one
of the major issues that cetaceans confront globally.
