The larva can look completely different from the adult form, for example, a caterpillar differs from a butterfly. Larvae often have special (larval) organs which do not occur in the adult form. The larvae of some species can become pubescent and not further develop into the adult form (for example, in some newts). This is called neoteny.

It is a misunderstanding that the larval form always reflects the group's evolutionary history. It could be the case, but often the larval stage has evolved secondarily, as in insects. In these cases the larval form might differ more from the group's common origin than the adult form.

Cutaneous larvae migrans (also called "creeping eruption" or "ground itch") is found in southeastern and Gulf states, and in tropical developing countries.
Cutaneous larva migrans (CLM) is a cutaneous lesion produced by percutaneous penetration and migration of larvae of various nematode parasites, characterized by erythematous, serpiginous, papular, or vesicular linear lesions corresponding to the movements of the larvae beneath the skin.
Larvae remain viable in soil/sand for several weeks.
Cutaneous larva migrans often presents itself as skin dermatitis.
The hook worm is the most common species of cutaneous larva migrans, and is often found in the stool of dogs and cats, unlike the round worm, which is found in the stool of raccoons, more commonly in the Midwest.
The majority of infections is seen in the southeastern United States, and is commonly seen on beaches where individuals are walking their dogs.
