Beaches See Odd Things Wash Up
(Oregon
Coast) - Interesting things have been washing up on Oregon beaches
lately. A species of shark that rarely washes up on shore was found,
and a creature known as a “purple sail” is starting
to make its annual appearance on the Oregon coast.
Seaside Aquarium’s
Tiffany Boothe said a sevengill shark wound up on Sunset Beach last
Thursday. While the species is not rare, it is rarely seen washing
up on Oregon’s coast. “They are offshore, deep water
sharks (about 1,000 feet to 1,800 feet)," said Boothe. “They
are slightly aggressive, often hunting in packs and feeding on fish,
marine mammals, and sometimes even each other. The one we recovered
and buried was nine feet long and about 146 lbs. It had been dead
a while and it had a hole in its side.”
Boothe said
the largest recorded sevengill was 9.8 feet and 236 lbs.
Aquarium manager
Keith Chandler referred to them as “simply a cool looking
shark.”
“I read
they hunt in packs,” Chandler said. “They don’t
wash up here much because they’re so far out and live so deep.”
In
the realm of beach wonders, velella velella are starting to show
up on the beach, said Boothe. These small, purplish, slimy things
wash up in great numbers in spring or early summer. Nicknamed “purple
sails,” this form of jellyfish brings out the seagulls to
feed on them when they wash up, and they start to smell rather pungently
after a while.
Once they dry,
they lose their purple color and become translucent.
“Walking
along the beach, you may have noticed slimy, iridescent blue discs,”
Boothe said. “Purple Sails have clear a ‘sail’
that helps them catch the wind. However, when the wind blows out
of the Northwest, these little guys get stranded on the beach. Unlike
the more common jellies, the purple sails do not sting. They capture
their food while drifting on the surface of the ocean with small,
sticky tentacles. They feed on fish eggs and small planktonic copepods.”
David Johnson,
owner of Cannon Beach Fultano’s Pizza in Cannon Beach, spoke
on the cell phone to Beach Connection while standing near the beach.
“I can see them from here,” Johnson said. “There’s
a line of them at the tideline.”
In Arch Cape,
just south of Cannon Beach, Arch Cape House co-owner Bob Shaw said
the purple sails have piled up to about six inches on that beach
Wednesday. "I can see them floating in big groups just offshore,"
Shaw said. "Then they'll sometimes get pushed up onto the beach."
Boothe said
they can be found in most oceans of the world, preferring warmer
waters. They can reach sizes of four inches in length and three
inches in width.
In
the meantime, a recent spate of “ocean
burps” on the north coast yielded some unusual finds for
the Seaside Aquarium. Found among these upwellings of objects churned
up during stormy periods was a set of squid eggs, which Boothe and
Chandler moved into a tank to see if they would hatch. Boothe said
the eggs are starting to form, and it looks like they may have a
small group of infant squid on their hands soon.
Chandler said
these look like a jalapeno stuffed with tapioca. The shells these
come from contain hundreds of little squid eggs. “We’ve
done this before, and I guess they’ll hatch in a month or
so,” Chandler said. “We’ve never been able to
raise them, however. They’re just too hard to feed or to find
stuff to feed them. They need a lot of tiny plankton. So once they
hatch, they’ll go away pretty fast.”
