Caecilian by David Raju
Caecilians lack limbs and this makes smaller specimens look like worms, though they are actually amphibians that can grow to lengths of up to 1.5 m., when they are often mistaken for snakes. Living largely underground, they are among the least studied of all amphibians. By coiling around her eggs, this caecilian mother is able to monitor humidity, pH levels and temperature and may even choose to relocate the clutch to avoid desiccation.
