Amphibians

At Up Yonda Farm, amphibians can be found throughout our forest and in our pond. These generally small, cold blooded animals spend part of their lives in the water and part on the land and the word "amphibian" actually means "on both sides of life". This group of animals includes almost 6,500 species and is split into three main groups; frogs and toads, newts and salamanders, and limbless amphibians.

Here is a closer look at some of the amphibians you might encounter on a visit to our center:

 

Red Spotted Newt - Notophthalmus viridescens

These pictures show the adolescent and adult stages of this animal’s life cycle. Young newts are called red efts and live on land for about two years after hatching from eggs in the water. When it is time to come back to the water, the eft undergoes several changes. First, their base skin color changes from bright orange to a dull, green. Second, their tail, which was once round becomes flat in order to be used for swimming. Adult newts can be found in many ponds and lakes throughout the Adirondacks, while the red efts can be found wandering through damp areas of the forests.

 

Green Frog - Rana clamitans

Green frogs are very common in the Adirondacks and here at Up Yonda Farm. There color can vary, but is always some shade of green. The sound these frogs make is similar to that of a broken banjo string. Can you say, “Ga-gunk?” Green frogs can get fairly large and are sometimes confused for larger bullfrogs. However, as you’ll notice in the picture, there is a line, called a dorsa-lateral ridge, which starts behind the eye and runs down the entire length of the Green frog’s body. This ridge on a bullfrog wraps around the ear or tympanum, but does not continue down its back.



American Toad -
Bufo americanus

Toads are often confused with frogs, but there are several differences between the two. The main difference is that frogs have smooth skin, while toads have many bumps or warts. There is also a difference between the eggs of these two amphibians. Frogs lay their eggs in a big mass, while toads lay their eggs in long strings. You will most likely find frogs around standing water, such as ponds and lakes, while toads are more of an inland species.
