A choir of bell jellies!! 

Based on the reaction from yesterday’s beachcombing Instagram Story, we went back to Asilomar State Beach to share our findings with Periscope and Facebook Live. 

After spending some time with various algae and moon jellies, we ventured down the beach only to find that Polyorchis bell jellies were also making their way around the Monterey Peninsula! 

Bell jellies are different from moon jellies—they’re a hydrozoan medusa, not a scyphozoan medusa. They’re crystal clear with filamentous guts and gonads, and with conspicuous red eyespots along the eye of their bell, earning them the name “red eye medusa.” 

You never know what you’ll find on the beach!

Coral: animal, vegetable, or mineral? 

Animal! Corals are actually made up of tiny animals called polyps. These polyps have little tentacles that they use to reach out and grab food, which they funnel in toward their stomach. 

Most coral polyps are nocturnal and retract inside the coral skeleton during the day. But on a night dive in places like Flower Garden Banks National Marine Sanctuary you might get to see the polyps in action!

Royal starfish (Astropecten articulatus)

The royal starfish is a West Atlantic sea star of the family Astropectinidae.The species of starfish Astropecten articulatus, commonly known as the
Royal Starfish is characterized by its bold colors. It has a purple
granulated disk, which is the central region of the sea star, and the
purple color continues to extend to its five flat rays, which are its
arms. A. articulatus feeds by swallowing its food whole and digesting it in
its stomach, like other members of the genus Astropecten. However,
unlike other species in the same genus, A. articulatus consumes
significantly more organisms.A. articulatus also feeds on a diverse number of organisms.

As someone that has grown up surrounded by beaches and done surf life saving, I know how the sea works. Lots of people dont. Every summer multiple tourists die here because they don’t respect the sea, if you’re going to the coast, here’s a thing I saw on Facebook.

Not the narwhals!!!

Narwhals, walruses are most at risk from booming Arctic ship traffic

Melting sea ice means more for whales and polar bears than simply habitat loss. A new study suggests that a dramatic jump in Arctic shipping traffic, thanks to longer open-water seasons, could put a host of Arctic-dwelling marine mammals at risk.

As summer sea ice coverage retreats, shipping routes such as the Northwest Passage have become ice-free during warmer months, boosting the number of seagoing vessels by three-fold in some regions. With some projections suggesting the Arctic’s summer sea ice could vanish by 2040, such traffic is only expected to balloon further.

The more ships that pass through, the more likely mammals are to be struck, stressed by underwater noise, or have their daily activities interrupted.

So pretty.

Did you know that some species of starfish have the ability to regrow an a complete new central disc and body from a single arm?

More commonly in other starfish species, a severed limb will only be able to regenerate into a full-grown #starfish if it is already attached to at least a portion of the central disc of the animal.

Amazing!!

This is actually a test showing how sponges pump water through themselves for filter feeding!
They simply colored the water around them so you could easily see the process 😀
