Zoom in on the serpentine locomotion of the limbless, amphibious caecilian over soil — Gymnophiona Caecilian moving over soil.

Caecilians, which typically lead subterranean lives with limited vision, rely on specialized sensory organs to navigate their environment and locate food. They use a chemosensory tentacle located on each side of the head to detect their prey, which primarily consists of earthworms and other soft-bodied organisms.1234
