Shrimp IDs galore!!

Post by Chenari »

Alrighty I'm back on the site with a vengeance. Tonight, we're taking a look at many shrimps that have accumulated in my To be IDed folder and I'm hoping Greg may be able to shed some light on the subject. *ahem*

Subject #1

I don't know what this may be, my best guess is Mesocragnon munitella. ... Don't remember the depth and location. Which is an issue with almost all of these. Sorry. :questionmarks: :dontknow:

Subject #2
Best guess: Heptacarpus palpator?

Subject #3
This one may be tough considering the angle of the shot and... it has me completely stumped.

Subject #4
Maybe a blade shrimp of some kind? (Also, secret #4.5 and 4.5.5, if anyone can name the worm to the left of this guy and the little shrimp up and to the left of him, that would be great too.)

Subject #5
Ok found one of these guys at Redondo the other night, maybe around 40fsw or so. It was boogiein along the bottom and was slow enough I could get this shot. Looking in Lamb & Handby, maybe an Opossum Shrimp?

Subject #6
Also from Redondo probably around the same depth as #5. Best guess: Spirontocaris ochotensis?

Subject #7
Yeah ok not shrimps, but still a stumper :questionmarks: . Found a bunch of these little guys on a crab shell at Redondo around Safety Stop depth. The shell was probably two or so inches across to give you an idea of scale. Those red eyes are really throwing me on this Id.

What makes you say Stiletto for 4? I don't see any blue spots or lines.

#3 was stiletto. General body proportions and posture, length of the rostrum. The blue spotting varies a lot; this one just has a little near the eyes.
