Discovery Bay boat launch

Has anyone launched there recently? Trying to find info on the web with conflicting results. The Port Townsend site says $10 launch fee (is there a box there to drop it in?) while the WDFW website says that motorized boats aren't allowed (which makes no sense...)

Re: Did It Actually Choke???

If you watch a fish, you'll see it moving its mouth as it breathes (more obvious on some than others- some look like they're gasping all the time). Water comes in through the mouth, passes through the gill arches and exits the opening behind the gill covers. Most fish can have something big in their...

Re: The Giant Manta, predator of the sea

I agree. Although strictly speaking the fact that it ingests larvae of various types (fish, crab, etc.) makes it a predator, it seems misleading to call it one. If you do, where do you draw the line? When a goat eats a plant with aphids on it, does that make it a predator?

Re: Did It Actually Choke???

Yeah, it isn't that uncommon for fish to choke to death when they "bite off more than they can chew", so to speak. Often happens with big-headed prey like sculpins- fish tries to swallow it headfirst, sculpin raises its head spines, and now its locked in and the fish can't spit it out. Thr...

Re: Critter ID

It's an amphipod- probably Podocerus cristatus. These come in all kinds of really cool colors.

Re: Do octos have 9 brains?

Each arm has a large ganglia that controls that arm, so they sorta do- with 8 arms that bend in every direction, that's a lot of processing for the main brain to have to deal with. So a lot of the stuff is subcontracted out to the ganglia to handle. The main brain is probably the only place where an...

Re: Need some ID help...

Pacific cod- longer barbel on chin than a tomcod. Plus it's way to big for a tommy.

Thinking maybe Olea hansineensis for the slug. I'm not a slug guy so take it with a grain of salt. (no salt on the slug, please)

Re: Invert ID

It's a deep blade shrimp (Spirontocaris prionota). Has its tail tucked underneath, which is a very common posture for this species.

Judging from the long tail, I'm leaning toward river otter too.

Stumbled across this- no idea if these are any good.

Olympus OM-D E-M5

Anyone on here use this camera, or familiar with it? I've read numerous reviews, ads, etc. for it but can't figure out the flash system. Some imply there's only a small add-on flash that attaches to the hot shoe, while others talk about having the flash flipped up or down. Looking at pictures of the...

Re: Shrimp on Anemone - Commensal?

It's a Spirontocaris lamellicornis- I've seen them hanging out under the tentacle canopy of several species of anemones, but hadn't seen one in the tentacles or on top before. Yelloweye's picture is of Spirontocaris snyderi, which is more common on anemones in Puget Sound. Both often wander away fro...

Re: Three Tree 2/19

It's also a Telmessus (helmet crab). In Acantholithodes the second pair of antennae would be lateral to the eyes, not between them.

Re: It Can't Be...Can It?

From the pics alone I'd guess Pododesmus (jingle shell) but 6" would be an awfully big one.
The other possibility would be a rock scallop that is just unusually smooth and symmetrical because it grew up on such a smooth surface. But I would expect that to be more round.

MY BABY! Lebbeus catalepsis, one of the species I discovered and named. First time I've heard of one from the inside waters; normally see them out at Sekiu. Awesome find!
