Recent Chelicerata / scorpion ID?

[Dimitar]

I see many of these similar to large scorpion.

Please help to identify if you know it?

I don't see such insects on the area, only near the river, below the rocks.  It seems it may live in the whater too , it has gills.  It seems to be more active in the water, but I find them outside the water, so they should be good for both.

Dobsonfly larva

[Fossildude19]

Moved to GENERAL DISCUSSION, as this is NOT a fossil 

 

I agree with Dobson Fly larva.

My father called them hellgramites. We would turn over rocks in riffles and catch them with a seine. We used them to fish especially for bass in rivers in Pennsylvania. We would hook them under the collar just below their head. Their pincers were very powerful. You must be careful handling them. I have been bitten right thru a fingernail. Their tail would hold on to rocks etc. They would change to having a reddish head color and would develop wings.

Certainly a larva, looks like a dragonfly IMHO

Definitely dobsonfly/hellgrammite. Although there are many differences between dobsonfly larvae and dragonfly larvae the most obvious in these pictures are external gills. Dragonfly larvae have internal gills and achieve respiration by forcing water in and out of the anus. The strong more rigid jaws of a dobsonfly are also evident in the picture. All dragonfly larvae have hinged labium. Although not pictured, dobsonfly larvae also have claws on the anal prohooks. Dragonfly larvae have more simple terminal appendages.

 

Megaloptera larvae in general are prized as good fish bait, especially for trout. As mentioned above they can bite hard but careful handling is easy.
