Where the living is easy. For now.

The day was bright and calm, the water in Brown's Bay smooth, almost glassy in protected spots. And the floats underneath the dock are beginning to collect intertidal communities again, after a thorough scraping earlier in the year.

Intertidal. Although these communities never have to deal with the changes and stresses that most of their relatives face twice daily. The tide never goes out for creatures attached to the underside of a dock; here, the current switches direction with the tide, bringing in fresh food and cold water and larvae looking for a place to settle, but it never exposes them to the air, nor to the unshielded glare of sunlight. An easy life, were it not for humans and their liking for clean plastic floats.

New plumose anemones, Metridium sp., and Vancouver Feather-duster worms, Eudistylia vancouveri.

A brilliant orange anemone; I'm not sure of the species. With mussels and limpets.

A colony of the Feather-duster worms. These worms prefer floats and pilings, with their constant water cover.

Another anemone, with an orange stalk. And several sea urchins, a couple of red spiral calcareous tubeworms (Pileolaria sp.), limpets, and one tiny brown chiton.

Moon jelly, Aurelia labiata. With kelp.

I liked this photo of the moon jelly heading into cover under seaweeds (mostly kelp) at the edge of a float, with the glare of the sunlight on the water.

Tiny, long, skinny fish. iNaturalist suggested Tubesnouts, Aulorhynchus flavidus. The scientific name of the genus is from the Greek for "flute snout". A good "snout" photo here.

Era una tarde tranquila en Brown's Bay; el cielo casi sin nubes, el sol brillante, el agua cristalina, sin olas. Y los flotadores debajo del muelle ya empiezan a adquirir comunidades de organismos intermareales, después de haber sido raspado hace unos meses.

Intermareales. Pero estas comunidades nunca tienen que sufrir los cambios y las dificultades que encaran sus parientes dos veces diarias. Aquí la marea nunca las deja expuestas al aire. Aquí la corriente va y viene, trayendo agua fria, alimentos, y larvas buscando sitio donde establecerse, pero nunca las quema el sol, ni las seca el viento. Vida fácil, si no fuera por los humanos con su preferencia por flotadores limpios.

  1. Anémonas juveniles, Metridium sp., con algunos gusanos plumero, Eudistylia vancouveri.
  2. Una anémona anaranjada, con mejillones y lapas.
  3. Una colonia de los gusanos plumero. Estos gusanos poliquetos prefieren sitios como este, flotadores y pilotes, donde permanecen siempre cubiertos de agua.
  4. Otro anémone con columna anaranjada. Y varios erizos de mar, y unos gusanos tubícolos con sus tentáculos rojos. Además, lapas y un quitón miniaturo, color café.
  5. Una medusa luna, Aurelia aurita, con algas marinas kelp.
  6. Me gusta esta foto, mostrando la medusa luna camino a esconderse bajo las algas marinas en el borde del muelle.
  7. Unos pececitos muy pequeños. iNaturalist sugiere que son Aulorhynchus flavidus. El nombre científico, del griego, significa "hocico de flauta".  Aquí hay una foto buena de la cara de este pez.

I'm having to moderate all comments because Blogger seems to have a problem notifying me. Sorry about that. I will review them several times daily, though, until this issue is fixed.

Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
