"Sea Lice?" on a Great Sculpin
"Sea Lice?" on a Great Sculpin
Spatman found this Great Sculpin last Saturday... a nice, somewhat colorful representation of the species, IMO!

Because of his size I decided to try for some closeups, and he obliged by staying still. As I looked at the pics (see above) I noticed what I can only describe as "blurry, whitish" areas on him. I had noticed the same discolored areas on Buffalo Sculpin before, and figured it was just because they sat around on the bottom. At first I thought it was probably schmutz in the water or my poor focusing skills, but on closer inspection I found what I call "Sea Lice" on him. I've seen these on salmon before, but not sculpins.

Is it coincidence that the "blurry whitish" areas have the Sea Lice on them? I suppose it could either be cause or effect, as in they could be there because of the areas or they could be the cause of them. The rest of his skin seems clear and healthy looking. Anyway, thought it was kind of cool and thought I'd post it here for some of our critter guru's to weigh in on if they so choose!

Tom, I notice the parasites on many of the Great and Buffalo Sculpins I see here on Whidbey, Some Lingcods have them too. THey are parasitic copepods I was told. Lepeophtherius of some sort.

Thanks Jan.
...and as long as we're being grossed out by parasites, I took this shot of a Brown Rockfish and noticed weird "danglies" on it's face.

Here's a blow up of the shot.

Again, not sure what they are, but the arms look almost "crustaceanish". Ideas Anyone?

This is an outstanding find, Tommy! These are parasitic copepods (slang: sea lice) of the lepeophtherius species; they are either lepeophtherius pravipes or lepeophtherius breviventris. Both are virtually identical to the naked eye. These little suckers infest the facial area of the unfortunate host (often sculpins), feeding off it. It is not lethal for the host, but once they're infested, it's for life. Gruesome.
Awesome Tommy!

So, I'm assuming you're referring to the ones on the rockfish, not the sculpin? Where did you find them? I haven't been through my books... don't remember seeing anything like it.

Hopefully help is on the way!
I sent off an email to Greg Jensen - hopefully he'll get a chance to look at the photo and know what the crab-leg-like thingies are on the Brown Rockfish.
Cross your fingers!

Seth, you surprise me!! You didn't know that Spotted Ratfish have a toxic spine on their dorsal fin, but you know all this about parasites??!?!Seth T. wrote:This is an outstanding find, Tommy!

Well, I've acquired some books recently and have been pouring through them. There is just fascinating stuff in our waters! Almost all of the parasitic copepods in our water are too small to see (literally specks floating around), but there are a couple of visible ones. The lepeophtherius parasite is absolutely what's infecting the sculpin. No question.nwscubamom wrote:

The rockfish is tougher but appears to be something in the Phrixocephalus species. This species is even worse than the one infecting the sculpin!

My favorite book by far is Pacific Northwest Marine Life. Unfortunately, it's almost the most expensive by far.
Looks like a great book though. It's a little cheaper at Amazon.com, about $48 including tax if you choose the free shipping option.Seth T. wrote:My favorite book by far is Pacific Northwest Marine Life. Unfortunately, it's almost the most expensive by far.
Googling around to see if I could find it even cheaper, I found this web site for PNW marine ID classes taught by the Vancouver BC aquarium and none other than the author, Andy Lamb: Pacific Northwest Marine Life Identification - a Field Course for Divers.
Only place I can find it cheaper was Overstock.com.

So I heard back from Greg Jensen and he thinks the little things on the Brown Rockfish might be leeches.

Is it just me, or do those things look like they have "joints"? Didn't think leeches have joints, or I could easily be misreading what they look like in the pic.
