My daughter and her friends found this, it apparently washed up on the shore of a body of water.

The tails are temporarily fused into one, in the image.
The thick furry hairs/gills are visible around the base of the abdomen.
The hind-legs stick out sideways and the other legs point forward. (one tarsal segment)

Moved from Mayflies.

this is a burrowng ephemeroid nymph

Predaceous Diving Beetle larva?
