They look like aliens, but they are very much real, and they have been captured on camera. This is our collection of the most bizarre-looking amphibians and reptiles known to occur in Ecuador.

10. Helmeted Brooding-Frog (Hemiphractus scutatus). It lives hidden in the leaf litter of the Amazon rainforest, and the females carry their eggs attached to their backs. These later hatch as miniature versions of the adults. No tadpoles at all!

9. Yellow-headed Thread-Snake (Epictia subcrotilla). It is smaller than most earthworms, and is often confused with one, but it has vertebrae and a skull.

8. Marine Iguana (Amblyrhynchus cristatus). This inhabitant of the Galápagos Islands is the only marine lizard in the planet, spending nearly 5% of a 24 h day in the water, grazing seaweed off the surface of rocks.

7. Amazon Horned-Frog (Ceratophrys cornuta). The mouth of this frog makes up nearly 50% of its body... and for a good reason. This species seizes almost any moving being that passes in front of it, even mice and snakes!

6. Northern Eyelash-Boa (Trachyboa boulengeri). It looks like a little dragon, moves like a slug, it is totally harmless, and feeds on fish and tadpoles, which it embraces and swallows whole.

5. Pinocchio Anole (Anolis proboscis). It is one of Ecuador’s most imperiled reptile species. It was thought to be extinct for nearly 50 years, and still, after its "rediscovery" in 2005, it remains hard to find. It is restricted to a cloudforest area of less than 500 km2 around the town of Mindo in Ecuador. The males have an elongated rostral appendage used for communication.

4. Yellow-blotched Glassfrog (Hyalinobatrachium aureoguttatum). This inhabitant of the Choco rainforest is regarded as the most translucent of all amphibians. Its heart, lungs, intestines, bones, and vascular system can bee seen clearly by looking at the frog from below.

3. Surinam Toad (Pipa pipa). This remarkable frog is flat, looks like a leaf, and it lives camouflaged among the leaf litter in ponds in the Amazon rainforest. The females carry their eggs embedded in the skin of their backs.

2. Giant Caecilian (Caecilia pachynema). Yes, it does not look so friendly. Caecilians are legless amphibians that spend most of their lives buried underground, and often come to the surface during torrential rainfall in tropical jungles. They are voracious predators of earthworms, insect larvae, and even mice!

1. Matamata (Chelus fimbriatus). Yes, that's a turtle, and that snorkel between its eyes is its nose. This heavily camouflaged species lives among leaf litter in muddy ponds in the Amazon rainforest.
