Sea Anemones

Sea Anemones Go to War… Harris Beach State Park

/ Curt Mekemson / 24 Comments

It’s the first day of spring here in the Applegate River Valley, and behaving like it. I watched two male flickers (woodpeckers) strutting their stuff this morning for a female while she studiously ignored them by pecking at the ground. One very pregnant doe was busy chasing off her twins from last year. She’ll soon have a new fawn— or fawns— to take care of. And, the swallows have arrived back in our neighborhood. Their aerial performances are truly amazing. Before long, they will start checking out our oak trees and bird houses for possible nesting sites. 

The first of our daffodils have burst into bright yellow blooms, shooting stars are covering the hillsides, and irises are popping up everywhere. Peggy and her sister Jane dug up our iris bed last year to separate the bulbs that were crowding each other out. Peggy discovered that there were more than she could possibly plant, so she started stuffing the extras into gopher holes and covering them— like you might sweep dirt under a rug. Well, that’s what I thought. The gophers will have a feast. I couldn’t have been more wrong. Each hole is now proudly sporting its own iris and Peggy is giving me an “I told you so” look.

And what else happened this morning? There was snow, rain and sunshine. Sometimes simultaneously. Spring has arrived for sure.

Meanwhile, I have a nasty cold. “We don’t likes it,” as Gollum of Hobbit fame would say. I have a box of Kleenex on one side and a paper bag on the other. I feel like I am an essential part of an assembly line for creating dirty tissues. Pull a Kleenex out of the box, sneeze into it, and stuff it in the bag. Repeat. I filled two bags yesterday. I’d be worried in this age of Covid, but my sniffer is working fine, I don’t have a fever, and Peggy and I had our second dose of Moderna in February. 

I was totally out of it yesterday and the day before. Instead of writing, I read a 400-page fantasy novel about a reluctant hero, a kick-ass princess, a unicorn without a horn, and a dragon that collected butterflies instead of virgins and gold. It was just what the doctor ordered. I’m almost human today, which is why I am back to blogging. Today I am returning to the tide pools of Harris Beach for a look at sea anemones.

The sea anemones at Harris Beach come in a variety of shapes and sizes. This was one of the larger ones we found, a giant, green sea anemone or Anthopleura xanthogrammica, if you want to be scientifically correct.
A more typical view. The tentacles are covered in stinging cells that the anemone throws into small prey like a harpoon. Once the poison has done its job, the anemone then uses its tentacles to work its prey into the gaping mouth seen in the center. When the feast is over it jets the leftovers out its mouth that has conveniently become an anus. I wonder if the anemone then gargles with sea water. The anemones stinging cells are more or less harmless to humans. How do I know this? I petted a few in my youth. The anemones don’t seem to like it; they immediately close up shop, like the anemones below.
A few of the big guys hanging out together at low tide. Anemones close up when exposed to air as a way to protect their tentacles. A small, dark fish is lurking in the remaining water. Some small fish seem to have a symbiotic relationship with anemones and swim among the tentacles, free of worry. Predators beware.
I found this interesting. A number to the anemones were covered in brightly colored pieces of rocks and shells. Scientists speculate that this serves as a natural sunblock when the anemone is exposed to air at low tide. I was curious about how they go about gathering and affixing their collection but couldn’t find anything about it.
Some smaller sea anemones live in colonies as seen here. These are clones of each other except they differentiate into scouts, warriors and moms. When two colonies meet, they go to war. It’s the scouts job to find new territory for the colony as it expands. When they come on another colony, the warriors take over by whaling away at each other with their tentacles. The ‘moms’ stay in the middle out of harm’s way. Next Friday, I’ll cover the other sealife we found in the tide pools.
