Reptiles And Amphibians. The colonies are firm, can have weird crusty-looking things on the outside, and never have embryos on the inside.
Despite being fairly large and having an extremely broad range, the spotted salamander is actually pretty hard to, well, spot. They can reach 9 inches in length and are prevalent in mature deciduous forests from eastern Canada throughout the eastern and midwestern United States. But these secretive salamanders spend almost their entire lives hidden under rocks or logs or in the burrows of other forest animals. They will populate upland forests and mountainous regions, but are most common in moist, low-lying forests near floodplains. They emerge from their subterranean hiding spots only at night to feed and during spring mating. They will actually travel long distances over land after a heavy rain to mate and lay their eggs in vernal pools and ponds. Visually striking, these stout salamanders are bluish-black with two irregular rows of yellow or orange spots extending from head to tail. Like many other salamanders, they secrete a noxious, milky toxin from glands on their backs and tails to dissuade predators. Their diet includes insects, worms, slugs, spiders, and millipedes. Spotted salamanders' numbers are generally stable throughout their range, but they are very sensitive to changes in their ecology, and rising water acidity in certain habitats is negatively affecting their population.

With winter concluding in Northern New England and already past farther south, amphibians in the northeast are migrating to their breeding habitat and beginning to lay eggs. Many of the species that breed in the early spring seek temporary bodies of water to lay their eggs, such as vernal pools, which dry during the summer and are free of fish that eat amphibian eggs. While most frogs and salamanders only spend a brief period of time congregated at breeding sites, the eggs will remain behind for up to a few weeks or so, which makes the eggs a useful way to tell which species live in an area if you know how to identify them. Thankfully, is not very difficult to tell most eggs apart once you learn their field marks, which is what I will show you in this post. This post is intended for use in the northeastern United States and covers all of the spring-breeding species found in Northern New England, but is also useful farther south, although the farther south you are the more species you may encounter. The post does not deal with mid-summer breeders such as Bullfrogs and Green Frogs, or species that do not lay noticeable egg masses such as Eastern Newts or Spring Peepers, which all lay individual eggs or groups of eggs attached under leaves and debris. Keep in mind also, that egg masses deteriorate in form as they age and older masses may be tattered, torn, or completely separated into a film. Note: some photos depict egg masses that are in hand and out of the water. Removing eggs from the water can damage them and doing so is not recommended in most circumstances. These photos were taken to help people learn how to identify egg masses and the eggs were handled with incredible care. Removing eggs from the water is not necessary for identification in the field. Telling the difference between frog and salamander eggs is quite easy. Frogs lay individual clear eggs with a visible embryo contained within each egg. With frogs, the outside edge of the egg mass is made up of the eggs themselves. Spring-breeding salamanders in the Ambystoma genus take it a step farther and coat the entire egg mass with an additional layer of gel. These two photos demonstrate the difference clearly:. Frog eggs. Notice that you can easily see the contour of each individual egg on the outside of the mass:. Salamander eggs. Notice that there is a layer of gel surrounding the mass of eggs. If you look closely, you can still see the clear outline of each egg within the mass:. This extra layer of gel on salamander egg masses is thought to provide the eggs some protection against predators such as the dreaded Eastern Newt, which apparently just eats its way past the gel anyway:. You would expect to find Wood Frogs breeding in ponds, vernal pools, and marsh edges in or near forested habitat at a wide range of elevations as soon as the snow melts and the ground thaws. A typical egg mass can have between and eggs. The embryos start out black on top and white on the bottom, as do most open-water amphibian eggs, but as the embryo develops into a tadpole the white is lost. A fully-formed mass that has been in the water for a day or so is about the size of a softball and the clear space between the embryos and the margin of each egg is many times greater than the width of the embryo. At a glance, Wood Frog egg masses underwater will look something like this:. Often, groups of Wood Frogs will lay their eggs in close proximity, usually on emergent vegetation or submerged tree branches:. When Wood Frog eggs are laid, however, the masses are much more compact. Directly out of the frog an egg mass is smaller than a golf ball, but swells to full size within hours. Leopard Frog eggs look a lot like Wood Frog eggs with a couple key differences. The embryos are about the same size mm , but the eggs themselves are much smaller and tighter. The clear space between the margin of the eggs and the embryo is usually the about the same thickness as the embryo itself remember, the clear space in a wood frog is much greater. Because Northern Leopard Frogs lay more eggs per mass than Wood Frogs , but the eggs are much smaller, the entire egg masses end up being about the same size roughly baseball to softball sized. To the best of my knowledge, Northern and Southern Leopard Frog eggs are indistinguishable from each other. Notice how tight the egg mass is compared to those of Wood frogs, which have much more clear space between the embryos. Leopard Frogs typically lay their eggs in lake and river floodplains where sedimentation and silt can build up pretty quickly. Remember that Wood Frogs tend to breed in ponds and vernal pools. Sure, there is some overlap in breeding habitat between Leopard and Wood Frogs, but knowing the typical breeding habitat for each species can help in many cases. Pickerel Frogs have very similar egg masses compared to Leopard Frogs, but notice how the Leopard Frog eggs are black on top and white on bottom. Pickerel Frog eggs are brown on top and yellow on the bottom. Other than that the eggs are pretty much the same. If you can identify Leopard Frog eggs you can identify Pickerel Frog eggs. The egg masses are almost exactly the same except instead of the eggs being black on top and white on bottom, Pickerel Frog eggs are brown on top and yellow on bottom, which is unusual for amphibians that lay eggs in the open. Pickerel Frogs are usually found in upland habitats, typically breeding in the margins of ponds, small lakes, and wetlands, compared to Northern Leopard Frogs which most often breed in lowland floodplains. Habitat counts! You might read that Pickerel Frog egg masses are plinth-shaped. Other sources say the egg masses are spherical, which is more consistent with my observations. A single strand could have between 2, and 20, eggs depending on the size of the female. Breeding occurs in the warmer months mid-summer in Vermont. If you live in a place with both species then you can use habitat as a clue, but not a very reliable one. The two species can also hybridize. Go figure.
