kahepaiksel

kahepaiksel is an Estonian word that translates to amphibian in English. Amphibians are a class of cold-blooded vertebrates that are distinguished by their dual life, spending part of their lives in water and part on land. This characteristic is reflected in their name, as "amphibian" comes from the Greek words "amphi" meaning "both" and "bios" meaning "life."

In Estonia, kahepaiksel refers to animals such as frogs, toads, newts, and salamanders. These creatures typically begin their lives as aquatic larvae, breathing with gills, and undergo a metamorphosis to develop lungs for terrestrial respiration. Their skin is permeable and moist, which is crucial for gas exchange and keeping them hydrated, but also makes them vulnerable to dehydration and pollution.

Estonian wetlands, forests, and meadows provide habitats for several species of kahepaiksel. Their presence is often an indicator of a healthy ecosystem. Conservation efforts in Estonia focus on protecting these fragile environments to ensure the survival of their amphibian populations. The decline of kahepaiksel populations globally is a concern, and understanding their ecological role is vital for biodiversity.
