Onychophora: Anatomy and physiology, Distribution and habitat & Behavior

Onychophora /ɒnɪˈkɒfərə/ (from Ancient Greek: ονυχής, onyches, "claws"; and φέρειν, pherein, "to carry"), commonly known as velvet worms (for their velvety texture and somewhat worm-like appearance), is a phylum of long, soft-bodied, many-legged animals. In appearance, they have variously been compared to worms with legs, caterpillars, and slugs. All…
