Land slug (likely a juvenile leatherleaf slug)

Moist soil, leaf litter, gardens, plantations, and other humid terrestrial environments; often active at night or after rain.

Primarily feeds on fungi, decaying vegetation, algae, and living plant tissue. It scrapes food with a radula.

A mucus-covered, shell-less gastropod that moves slowly and contracts when disturbed. Most are nocturnal; many species are hermaphroditic and lay eggs in moist shelters.

Generally harmless to people, though some species damage crops and ornamental plants. It contributes to decomposition; avoid eating raw slugs because some can carry parasite larvae.
