What are Salamanders?
So, you’re new to the world of live salamanders and wondering what they’re all about? Let’s start with the basics. Salamanders are a type of amphibian that belongs to the order Urodela or Caudata. They’re closely related to frogs and toads, but unlike their frog cousins, salamanders don’t have a long period of aquatic larvae development.
One of the most distinctive features of salamanders is their skin, which can range in color from dull brown to vibrant orange and everything in between. Some species even have specialized glands on their skin that produce toxins as a defense mechanism against predators. In terms of physical characteristics, salamanders typically have four limbs (although some species may have fewer or more), and they’re often relatively small compared to other amphibians.
Another key difference between salamanders and frogs is their ability to regrow lost limbs. This unique feature has led scientists to study salamander regeneration in the hopes of gaining insights into human tissue repair and development.
Evolutionary History of Salamanders
Salamanders have been around for a remarkably long time, with their evolutionary history dating back to the Paleozoic era, over 360 million years ago. During this period, they emerged as part of the larger group of amphibians, which also includes frogs and caecilians. As the earth’s climate changed and new environments developed, salamanders began to diversify and adapt to their surroundings.
Over time, salamanders have learned to thrive in a wide range of habitats, from the driest deserts to the wettest forests. Some species have even adapted to live underground, using burrows as shelter and protection from predators. One notable example is the olm (Proteus anguinus), a blind salamander that lives in complete darkness beneath the surface of European caves.
Today, there are over 750 known species of salamanders, ranging in size, shape, and color. While their diversity is impressive, it also serves as a reminder that many species are threatened or endangered due to habitat loss and other human activities.
