A high angle view of the Yasuni National Park in the remote jungles of Ecuador.

YASUNI NATIONAL PARK, Ecuador -- Ecuador is a beautiful country on South America's west coast, and despite its small size, it has an extremely diverse landscape -- including the Amazon rainforest, the Andean highlands and the Galápagos Islands. I recently conducted a research expedition to Ecuador, and it was an unforgettable experience to say the least.

During our travels through the mainland and the Galápagos, we encountered an incredible diversity of frogs, snakes, lizards and salamanders. Without further ado, here are my top 10 favorite amphibian and reptile encounters:

1. Rain Frogs

Our first night in Sumaco, Ecuador was a rainy one, perfect conditions for peeping rain frogs.

2. Fringed Leaf Tree Frog

The Fringed Leaf Tree Frog (Cruziohyla craspedopus) is one of the most fantastic amphibians in the Neotropics.

Living in high canopies, the Fringed Leaf Tree Frog is very difficult to spot.

3. Banded Tree Anole

A female Banded Tree Anole, characterized by those brilliant blue eyes.

This male Banded Tree Anole's bright dewlap is used to grab the attention of females and to defend his territory.

5. Glass Frogs

Glass Frogs are incredible little amphibians. Their backs are mainly lime green but their underside is totally translucent. You can even see their little hearts beating.

Glass Frogs are one of my favorite critters in the cloud forest of Mindo. They lay their eggs in a clutch on leaves above a stream; when the tadpoles are developed enough to swim, they drop down into the water and venture off to become beautiful translucent frogs.

6. Tropical Salamander

Tropical Salamanders win the most adorable, squishy animal award, hands down.

We typically spotted these little guys on night hikes in Sumaco.

7. Geckos

A large gecko we found snacking on moths near a light at the Yasuni Research Station.

If it weren't for geckos, humans might never have invented sticky adhesive nanostructures. Gecko toes contain thousands of hair-like setae, and it wasn't until 2002 that the mechanism for their adhesive ability, which is based on van der Waals forces, was discovered.

8. Galápagos Iguanas

Galápagos Marine Iguanas (Amblyrhynchus cristatus) have short, flat noses so they can feed on algae in the ocean.

Current research and genetic data on Land Iguanas (Conolophus subcristatus) suggest the Marine Iguana split from the Land Iguana around 4.5 million years ago, forming the two different and distinct species we see today.

9. Giant Galápagos Tortoise

Galápagos Giant Tortoises likely arrived at the islands around 2-3 million years ago by drifting from South America before diversifying into as many as 15 subspecies.

Giant tortoises are one of the longest-lived vertebrates, living over 100 years on average.

10. The Rare Pinocchio Lizard

The Pinocchio Lizard (Anolis proboscis) is an endangered anole found in the cloud forest of Mindo; only the males possess strange horns.

The Pinocchio Lizard has a very mossy pattern to camouflage with the wet moss in the canopy.

The Pinocchio Lizard's nose is used to attract females and defend territory from rival males.

I hope you enjoyed these incredible reptiles and amphibians as much as we did. Special thanks to Lucas Bustamante from Tropical Herping and thanks to TROPIC for hosting us during our visit to the Galápagos. If you want to plan your own trip, visit Destination Ecuador.

The Coolest Insects EVER

The Western Ghats are a globally recognized repository of biological diversity for our planet. We know very little about most species found here, particularly the ecologically sensitive and spectacularly beautiful 179 amphibians. Astonishingly, 87% of all Western Ghats frogs are endemic and found nowhere else on the planet. Our collaborative research project with Drs Paul Robbins and Ashwini Chhatre examining biodiversity in production landscapes of Ghats unearthed some spectacular amphibians in 2013.

Lost to science for almost 75 years and rediscovered recently, Nyctibatrachus kempholeyensis was first described by the legendary Indian herpetologist C.R. Narayan Rao in 1937 and can be recognized by their distinct cricket like call.

Rhacophorus lateralis was rediscovered in 2000 and is thought to be extremely localized. We observed more than 200 individuals of this species in a pond.

Nyctibatrachus minimus is the smallest known frog in India.

Exhibiting interesting behavior from foot flagging to gliding, frogs in the Ghats leave much to be discovered by scientists and naturalists.

The foot flaggers Micrixalus species found typically in shallow fast-flowing streams, are thought to use “foot flagging” to communicate when vocalizations are drowned out by water flow.

Rhacophorus malabaricus. Photo by: Shashank Dalvi/Krithi Karanth/CWS.

The gliding abilities of Rhacophorus malabaricus aided by long skin between their fingers allow these frogs to cover distances of 10 feet in one leap! They also build foam nests and we observed interesting behavior such as cannibalism among tadpoles.

Many of these amphibians are strikingly beautiful and extremely adaptable.

With its bright colors and listed as Endangered, Ramanella trangularis was seen to be using strategic locations such as crevices and tree holes to amplify its calls.

Rarchestes luteolus. Photo by: Shashank Dalvi/Krithi Karanth/CWS.

Raorchestes luteolus also known as the blue-eyed bush frog is common to the Ghats.

Raorchestes glandulosus. Photo by: Shashank Dalvi/Krithi Karanth/CWS.

Some species such as Raorchestes glandulosus come in a range of colors often all found in one location.

Polypedates maculatus. Photo by: Shashank Dalvi/Krithi Karanth/CWS.

Polypedates maculatus can adopt lighter skin colors and secrete mucus to regulate moisture loss.

Indriana species with eggs. Photo by: Shashank Dalvi/Krithi Karanth/CWS.

Many of these frogs display unique abilities in building nests and laying egg clutches such as Indirana species.

Nyctibatrachus grandis. Photo by: Shashank Dalvi/Krithi Karanth/CWS.

Nyctibatrachus dattatreyaensis. Photo by: Shashank Dalvi/Krithi Karanth/CWS.

And we are still discovering new species including Nyctibatrachus grandis (with its owl-like call) whose males defend egg clutches rather aggressively, and Nyctibatrachus dattatreyaensis only found in a 30 sq km of the entire 160,000 sq km Ghats.

Duttaphrynus melanosticus. Photo by: Shashank Dalvi/Krithi Karanth/CWS.

Unfortunately, most of these endemic species are threatened by range of human activities, resulting in fragmentation and disruption of habitat quality that they are particularly sensitive to, causing visible deformities. We observed deformities including one in Duttaphrynus melanosticus.

We were able to find many amphibians in unprotected and heavily human-used habitats. We believe there is a urgent need for immediate investments in improving the scientific understanding and conservation efforts focused on these environmentally sensitive flagships of the Western Ghats.

Centipedes. There is more to a centipede than its many legs, and its habit of darting out of dark places. One of the first lifeforms to turn up on land, some centipede fossils date back to about 450 million years ago. They have been evolving steadily since, with some estimates showing about 8,000 species today. Not even half of these species have been taxonomically described.

Photographers threatening the already-abused slender loris

(03/12/2013) Caught in a beam of torchlight, the eyes of the slender loris reflect back a striking glow. In an effort to better understand these shy, nocturnal primates, a team of researchers set out to the Western Ghats of India. The resulting paper: Moolah, Misfortune or Spinsterhood? The Plight of the Slender Loris (Loris lydekkerianus) in Southern India was published in the Journal of Threatened Taxa in January of 2013. Forest walks and interviews with the Kani people, who live in close proximity to the lorises, supported evidence of a surprising new threat to the lorises: photographers.

Six months ago, before large-scale mangrove planting of the area, if someone were to walk through the banks of the mangroves in the Western Ghats he would see many fishermen casting their long nets and wires, time and time again noticing pieces of trash such as plastic grocery bags tangled in the nets.

Recommendations to save India’s Western Ghats creates political stir

(08/20/2012) A massive expert panel report on the conservation of the Western Ghats has caused a political stir in India. The report, headed by noted ecologist Madhav Gadgil, recommends that the government phase out mining projects, cancel damaging hydroelectric projects, and move toward organic agriculture in ecologically-sensitive sections of the Ghats. The report, which was leaked after the government refused to release it, has yet to be implemented. Recently dubbed a UNESCO World Heritage Site, the Western Ghats is one of India’s largest wildernesses and home to thousands of species, many found no-where else.
