Using a handy guide provided, Matthias pointed out the critter was a zoea, a very young crab moving into the next stage of its life, a megalops.

The Zoea was formerly regarded as a recapitulation of an ancestral form, but there can be no doubt that its peculiarities are the result of secondary modification.

The various larval forms, especially the nauplius and zoea, were supposed to reproduce, more or less closely, the actual structure of ancestral types.
