Adult male, protruding

Same as previous, with different focal plane highlighted

At left: L3 male with slightly less developed tail. The animal on the right is L4 male with more developed tail.

Male animal: Fan, hook, half of the body

L4 male with underdeveloped tail. (Not yet developed fan. Looks like tulip shape under the dissecting scope, but not under the DIC one.)

A closer (20X) view of L4 hermaphrodite, so you can see the structure of the vulva. The vulva at this stage is a pronounced ring under a dissecting scope.
