The Daily Journal (San Mateo County), 7/27/16. "Female humpback whale washes ashore near Pescadero."

Just saying hello I'm here. |
"A 32-foot female humpback whale washed up ashore at a beach near
Pescadero in San Mateo County and scientists believe it might have been
struck by a vessel, Marine Mammal Center officials said Tuesday.
|
Washed ashore, possibly strick by a ship. |
Six scientists from the Marin Headlands-based center and the
California Academy of Sciences in San Francisco responded Monday to
Bean
Hollow State Beach to perform a necropsy (same as autopsy) on the
juvenile humpback
whale, which is an endangered species. The scientists found massive fractures to the back of the whale’s
skull, evidence of
blunt force trauma consistent with a vessel
collision. It also had a cut on the front right flipper that could have
been from a previous entanglement, center officials said.
“Every whale stranding serves as an opportunity to learn about
these majestic creatures, and
how we can prevent future deaths,” Marine
Mammal Center research assistant Barbie Halaska said in a statement.
Humpback whales have been sighted along the San Mateo County coast recently as
they migrate north.

Some of you saw me in Pacifica? Gray-whales travel north too. |
Earlier this month, scientists from the two organizations
responded to
a 30-foot male humpback whale that also washed ashore at
Bean Hollow State Beach and had injuries consistent with a ship strike.
In recent years,
the Marine Mammal Center responds to up to 11 whale strandings per year, according to the center. Anyone who sees sick or injured marine mammals can report it to the center by calling (415) 289-SEAL."

recent months as they slowly move north, feeding on their migration
route. The whales are among the most endangered whales in the world.
Fewer than 10 percent of their original population remains. ... Nearly
1,400 humpbacks frequent the California coast in the summer and
fall now. The humpback's global population is estimated to be between
35,000 and 45,000."
Reference, mammal center and education. The Marine Mammal Center/Humpback Whale, .... "BEHAVIOR: Acrobatic humpbacks regularly breach
(jump
out of the water), stroke each other, and slap the water with their
flippers and flukes. Scientists believe
these activities are forms of
communication because they create a great deal of noise, which can be
heard at long distances under water. Humpbacks swim in groups or pods of
up to a dozen at calving grounds, and in smaller groups of three to
four during migration. Unlike other baleen whales, they can often be
seen feeding cooperatively."
