The pygmy web-footed salamander (Bolitoglossa pygmaea) is a tiny and special type of salamander. It belongs to a group called Plethodontidae, which are known as "lungless salamanders" because they breathe through their skin! This amazing little creature lives only in Costa Rica, a country in Central America. Being "endemic" means you can't find it anywhere else in the world. It was first described by scientists in 2009.

What is a Pygmy Web-Footed Salamander?
The pygmy web-footed salamander is one of the smallest salamanders. It gets its name "pygmy" because it's so tiny. "Web-footed" refers to its feet, which have some webbing between the toes. This webbing might help it climb or move around in its wet home.
How Big Are They?
These salamanders are very small. They usually grow to be only a few centimeters long. Their small size helps them hide from predators. It also allows them to live in tiny spaces within their habitat.
What Do They Look Like?
Pygmy web-footed salamanders often have dark colors. This helps them blend in with their surroundings. They might have shades of brown, black, or grey. Their skin is smooth and moist, which is important for how they breathe.
Where Do Pygmy Web-Footed Salamanders Live?
These special salamanders live only in Costa Rica. They prefer specific types of environments. They are often found in cloud forests or humid mountain areas.
Their Habitat
Their home is usually cool and very wet. They like places with lots of moss, leaf litter, and rotting logs. These spots provide shelter and keep their skin moist. They can be found hiding under rocks or inside bromeliads. Bromeliads are plants that grow on trees and collect water.
What Do Pygmy Web-Footed Salamanders Eat?
Like most salamanders, the pygmy web-footed salamander is a carnivore. This means it eats other small creatures. They are important parts of their forest ecosystem.
Their Diet
They mostly eat tiny invertebrates. These include small insects like ants and mites. They also eat other small creatures found in the leaf litter. They use their sticky tongues to catch their prey quickly.
Life Cycle and Reproduction
The life cycle of a salamander is fascinating. Pygmy web-footed salamanders have a direct development. This means they don't have a tadpole stage like frogs.
How They Reproduce
Female salamanders lay their eggs in moist, hidden places. These spots could be under logs or in damp soil. The eggs hatch directly into tiny salamanders. These young salamanders look like miniature versions of the adults. They do not need to live in water during their early life. This is different from many other amphibians.
Why Are They Important?
Every species plays a role in its environment. Pygmy web-footed salamanders are part of the food web. They help control insect populations. They also provide food for larger animals.
Conservation Status
The pygmy web-footed salamander is listed as "Vulnerable" (VU) by the International Union for Conservation of Nature (IUCN). This means they face a high risk of becoming endangered in the wild.
Threats to Their Survival
Their biggest threat is habitat loss. Forests are being cut down for farming or development. Climate change also affects their cloud forest homes. Changes in temperature and rainfall can make their habitat too dry. Pollution from pesticides can also harm them.
How Can We Help?
Protecting their habitat is very important. This includes preserving forests in Costa Rica. Reducing pollution and fighting climate change also helps. Learning about these amazing creatures is the first step to protecting them.
