OK ID fans... What is this?

[Bang Guy]

Found this critter in my Artemia culture tank after I drained it.


Info on the Culture Tank:
30 gallons
Salinity = 85ppt as measured by Refractometer
S.G. = (WAYYYYY off the scale of my hydrometer)
Temp = 72F
Ammonia = 0.5
Nitrite = 2ppm
Nitrate = over 100 ppm (off the scale)

I should add that the head is in the lower left and the critter is on its back.

That's an ugly spud

I doubt it is right, but I'll give it a shot. Using the Dichotomous Key on Dr. Ron's Website (without all the answers I might add) I believe it might be Echiuran worms. Phylum Echiura.

Another hint. I was totally stumped for several days and then it changed...

 

[Bang Guy]

OK, I was hoping to get some more obscure guesses.... but

It changed into a Mosquito and flew away...

Good greef.

That was a good one. So at what stage was it in when you took that photo? Was it a larve stage?

Strange that you should have Mosquito eggs in your sandbed. But I suppose you never know where your sand has been before you got it.

Atleast I am hoping you dont have misquito's in your basement.

I have absolutely no doubt that a mosquito layed eggs in the Brine shrimp tank. There's plenty of algae for them to eat or prey, whichever

I'd bet gut loaded mosquito larve would be excellent fish food!
