It's a bopyrid isopod- see the entry on it on pg. 13 of my newer book

Re: Leptasterias at junkyard

I don't recall seeing Leptasterias of any kind this far down in the Sound, although I did record seeing one near Tahuya on Hood Canal a long, long time ago. Most refer to the colorful ones like Jan posted as L. aequalis, while the greenish-gray ones are L. hexactis. Both are very common on Skyline w...

Re: Leptasterias at junkyard

I'm not sure that is a Leptasterias- thinking it might just be a juvenile Pisaster brevispinus with an extra arm. This has an obvious giant pedicellaria (at about 7 o'clock on the disk) and I don't think either of our local Leptasterias have these- can't see them in any of my pics or find any mentio...

Re: Victoria Diving

Ogden Pt is a must-do. Easy access, great day or night. Ten mile point is also excellent, but you'll want to hit slack on a day without a big exchange. Willis point is good and a great fall-back if it's too rough elsewhere.

Re: Whidbey Island Critters

Well, you saw how clumsy and slow it was walking around in the open. Once they're out of the burrow they're toast- he's probably in a staghorn's tummy by now.

Re: Alki Junkyard - Sea Spiders - 1/9/16

Sorry for the late response, just saw the question: yes, sea spider is the correct. Their relationship to terrestrial spiders is still a matter of debate, but it is a perfectly acceptable term.

Re: Whidbey Island Critters

Alex is correct in that the shape of the ghost shrimp's claw looks more like a gigas, but as noted the eyestalks are those of a californiensis. I've been fooled by ones like this in the past- it could be that regenerating claws take a while to develop the expansion that is normally seen in large cal...

Re: Whidbey Island Critters

I actually had an urchin that recovered from that- lost all its spines and I figured it was toast, but I never got around to removing it from the tank and it regrew them.

Yep, it's a type of polychaete worm called a scaleworm, due to the rows of "scales" running down the back.

Re: Zipper Tests - The Results Are In!

Thanks for the info on why they say that. I would think the biggest stress to that area would be when the suit is rolled up and the arms folded in- esp. if something is then set or dropped on top of the bag.

Re: Zipper Tests - The Results Are In!

My wife and I both have over 500 dives each on our Abyss suits with metal, across the shoulder zippers, with no leaks so far (knock on wood). All my previous suits had much shorter zipper lifespans, but none of those had a zipper flap. We do mostly shore dives so there's a lot of rubbing on the zipp...

Re: Lobster in Puget sound?

Judging from the color, the eggs looked like they were pretty well developed. I suspect the lobster was shipped in from the east coast already carrying them. Female lobsters with eggs are not supposed to be harvested (on the east coast that is- out here, any of them are fair game so it's good that y...

Re: Parasites

They are branchiurans, a type of parasitic crustacean. They are often referred to as "fish lice" but that name is also given to some very similar-looking parasitic copepods. The easy way to tell them apart is that branchiurans have a pair of eyes and copepods don't.
