Ravine Salamander

Posted on August 2, 2015 by tspuckler

This amphibian can easily be mistaken for the “leadback” phase of a Redback Salamander. It has short limbs and is somewhat worm-like in appearance and movement.

The background color is brownish black to black and flecked with a varying amount of fine silvery white to golden specks. This is Ohio’s most slender salamander. One-half of this animal’s total length is made up of its tail.

Ravine Salamanders reside in forests and are often found on the slopes of valleys and ravines where it lives among the leaf litter, hiding under logs, stones or stumps. Unlike many amphibians, this creature completely terrestrial, laying eggs on land. The eggs hatch as tiny juveniles.

During Spring and Fall they can be found on the surface under leaf litter and other debris, but they burrow into the ground or retreat into deep, moist crevices to avoid the warmer temperatures of Summer.

Adult Ravine Salamanders are 3–4½ inches in total length. They are found in eastern Kentucky, Ohio, southern West Virginia, western Virginia, northwestern North Carolina and northeastern Tennessee.

This is a species of amphibian is in the “lungless salamander” family, which contains many species. Like other members of its genus, Ravine Salamanders lack lungs and conduct respiration through their skin and lining of their mouths. For this reason they need damp conditions in order to function.

California Slender Salamander

Posted on May 2, 2015 by tspuckler

This creature is a lungless salamander that is found primarily in coastal mountain areas of Northern California. It is very commonly encountered and I’ve seen several on my current trip to the Golden State.

Its “slender” image comes from short limbs, a long, slender body with a narrow head and a very long tail. This gives them a worm-like appearance.

Like other lungless salamanders, they conduct respiration through their skin and their mouth tissues, which requires them to live in damp environments on land and to move about on the ground only during times of high humidity.

As you might imagine, an animal this small has plenty of predators. For defense. the California Slender Salamander Slender salamanders use several defense tactics, including coiling and remaining still, relying on cryptic coloring to avoid detection.

They also can uncoil quickly and spring away, repeatedly bouncing over the ground, then remaining still again to avoid detection. If grapped this amphibian can detach its tail, which wriggles on the ground to distract a predator from the salamander long enough for it to escape.

They are predators themselves, and use a sit-and-wait technique, catching prey that wanders by with their projectile tongue. Their diet consists of a variety of invertebrates, including springtails, small beetles, snails, mites, spiders and isopods.

The lifestyle of this tiny salamander remind me of one that I frequently encounter in my home state of Ohio – the Redback Salamander. Seeing either amphibian in the field is always an enjoyable experience.

Four-toed Salamander

Posted on August 12, 2014 by tspuckler

This small, slender salamander is orange to grayish brown above, sometimes with small black and bluish speckles on the sides. This is Ohio’s smallest salamander – and the first one I’ve ever found. Adults are 2 to 3 inches long; their tails make up over half their length.

Though it ranges throughout much of the state, it only occurs where boggy ponds or spring-fed creeks are available in or near damp wooded habitats. As its name implies, this amphibian has only four digits on its front and hind feet.

Four-toed Salamanders can voluntarily detach their tails, which continue to wiggle to distracting predators. This autonomization of their tails in unique. The tails of most salamanders must be grasped to come off.

It was cool to finally meet this uncommon and secretive creature in the wild.

Spring Salamander

Posted on April 29, 2014 by tspuckler

This amphibian is found in Canada and the United States. Spring Salamanders are semi-aquatic, spending a majority of their time in springs, wet caves, and cool, clear mountain brooks. Spring Salamanders can also be found under stones and logs near stream edges.

This is one of the largest species of lungless salamanders and can reach about 8 inches in total length. It is usually salmon-pink to brown-pink with a few small, dark spots on the back and sides, usually forming a row along the sides.

Because they are lungless, and obtains oxygen through its skin, the Spring Salamander is limited to areas where there is adequate oxygen and moisture. Though is not confined to the water, however, and will sometimes leave its aquatic habitat and venture out on land in search of food.

As an adult, the Spring Salamander’s tail has a prominent, knife-like keel on the top that enables it to swim in swift-moving water. Adults also have toxic, skin secretions and red coloration that mimics more toxic species, for protection from predators.

It is primarily nocturnal. The Spring Salamander hunts at night for a wide variety of food consisting of insects, crustaceans, centipedes, millipedes, earthworms, snails, spiders, and occasionally small frogs and salamanders.

It was pretty cool to see several of these amphibians in the wild during my recent trip to Kentucky.

Jefferson Salamander

Posted on April 14, 2014 by tspuckler

The Jefferson Salamander belongs to a group of amphibians known as mole salamanders, named because they spend most of their life underground. The only time you are likely to see them is now, when they are migrating to temporary pools in the woods to mate and lay eggs.

Egg masses contain 20-30 eggs are attached to fallen tree branches underwater. The time it takes for the eggs to hatch depends on water temperature and ranges from 2-8 weeks. The aquatic larvae complete metamorphosis in 2-3 months and like frog tadpoles, they go from an aquatic existence to a life lived on land. Here’s a newly metamorphosed individual that I found in July of last year.

This amphibian is usually dark gray and often has silver or blue specks on its sides. The secretive adults hide under stones or logs, in leaf litter and in burrows in hardwood forests with damp conditions. Around here they share their habitat with Spotted Salamanders, though they are much less common. They tend to be more slender than spotteds, but are about the same overall length (about 7 inches).

The Jefferson Salamander feeds on insects, spiders, earthworms, slugs, pillbugs and other invertebrates. Because the adult salamanders spend most of the time outside of the breeding season hidden, their exact feeding habits are not known. Ecologically, salamanders play important roles in the organization of many terrestrial and aquatic communities. They are increasingly being used as indicators of environmental heath.

But they have an additional value to humans in the form of medical research subjects. Salamanders have extraordinary ability to regenerate toes, feet and entire limbs – they are the only vertebrate that can do this. Understanding the basis for their limb and tissue regeneration could have significant implications for the field of medicine.

The Jefferson Salamander is yet another of nature’s mysteries, cloaked in dark coloration and living an underground lifestyle that we know almost nothing about. I’m lucky if a see one or two of these fine salamanders each year, and I was glad to come across one this week.

California Newt

Posted on March 31, 2014 by tspuckler

California Newts are large salamanders reaching a total length of around 8 inches. They are slow moving and have “expressive” faces. These amphibians have dry, warty skin that is not slimy and are light brown to black with a yellow to orange belly.

The California Newt has a unique way of fending off predators. First they raise their head and point their tail straight out to expose their bright underside as a warning. If the predator attacks, the California Newt secretes neurotoxin through its warty skin and can cause paralysis and or death to its attacker.

They spend the most of their lives under logs and in animal burrows during dry months. But during Spring rains, they migrate to breeding ponds. Several places in California close roads to insure the safe passage of these salamanders.

Newts eat mostly bugs and worms, as well as slugs and snails. When feeding, adults flip out their sticky tongues to capture prey. They can live up to 20 years in the wild.

Cave Salamander

Posted on October 4, 2013 by tspuckler

Are you ready to spend a few days in southern Illinois? I found this small cave in the “Land of Lincoln,” let’s see what creatures lurk inside.

Cave Salamanders! These exceptionally slender salamanders are usually around 6 inches in length. They are easily identified by their bright ground color. The young of this species is often yellow in color, while the adults are usually a bright orange with black spots randomly covering their body.

These colorful creatures remind me of geckos, the way they can run up the sides of cave walls. When pursued, a Cave Salamander scampers quickly, often waving its tail to distract attention away from its head.

Although it usually occurs in caves, this species also can live in wooded areas, along rocky streams and springs, under rocks on glades during the spring and even in wells and swamps.

Those living in caves live in the twilight zone, the dimly lit area beyond the cave entrance, but also occur far back in areas of permanent darkness.

The Cave Salamander’s diet consists mostly of small insects and other invertebrates. It’s always a thrill to encounter this exceptionally beautiful amphibian.

Northern Slimy Salamander

Posted on August 29, 2013 by tspuckler

There are several common ways a small and relatively defenseless animal might avoid being eaten by predators. One method might be blending in with the surrounding environment, thereby avoiding detection. Another tactic would be the ability to make a fast escape. Still another strategy to not be eaten is to be poisonous, or at the very least, distasteful. The Slimy Salamander, however, employs none of these techniques.

This amphibian might be better named if it were called the “Sticky Salamander,” because it secretes a glue-like substance from its skin when threatened. This substance can be very difficult to remove from hands or clothing. It prevents the animal from being eaten by some predators. It’s scientific species name glutinosus is the Latin adjective “sticky.”

The relatively cool, wet Summer we’ve been experiencing has made for ideal conditions to come across this woodland salamander and I’ve seen a few over the past several weeks. This attractive amphibian is black with a scattering of small silvery-white flecks all over it. The amount of flecking can vary among individuals; flecks may be absent on some and plentiful on others.

The Northern Slimy Salamander is found throughout much of the northeastern United States. Though slender, it is relatively long, reaching total lengths of over 7 inches. It likes to hide under rotting logs or in stumps. Although entirely land-dwelling, it needs a damp habitat. It is a lungless salamander, so wet conditions are essential, because it breathes through its moist skin.

The Slimy Salamander emerges from its burrow at dusk and retreats at dawn. It hunts insects and other small invertebrates and catches food by flicking out its tongue. It is occasionally active on rainy days. Not only is it good looking, but the Slimy Salamander is also a true original when it comes to defending itself.

Northern Red Salamander

Posted on April 29, 2013 by tspuckler

This past weekend I accompanied 18 high school students to south-central Ohio to explore some of the state’s natural wonders. We found a creek and Adam, Pat, Jen and Claire decided to turn a few logs in the area.

Our efforts paid off when we found this strikingly bright red amphibian with scattered black dots.

Jen thought is was an awesome find, and I agreed.

The habitat for this colorful creature is under rocks and logs in and around cold, clean springs and adjacent brooks.

The Northern Red Salamander is a large (up to 8 inches) amphibian. This species has a distinctive, bright yellow iris and a stout body.

Older examples of this salamander, like this one I found a few years ago, are less brightly colored and often somewhat purplish.

Spotted Salamander

Posted on April 2, 2013 by tspuckler

Though it’s rather large and has a wide distribution, the Spotted Salamander is actually pretty hard to…spot. These stout-bodied amphibians spend most of their lives underground. They are usually found in low-lying hardwood forests.

Because of their subterranean lifestyle, they are seldom seen except in March. During an especially stormy night on March 11, many of these salamanders could be seen migrating after dark during the rainstorm.

They make their way to fish-less pools of water, but even then, they are only active at night. In their underwater courtship dance, the male swirls around, turns about and nudges the female.

Since it became so cold the days after the migration occurred, the amphibians have been in a sort of “suspended animation,” buried in the mud at the bottom of the pool. It warmed up in the last few days though and they are “back to business.”

Here’s what one of their fist-sized egg masses look like. The eggs expand after the salamander lays them. They are coated with a thick jellylike substance that holds all the eggs together, anchored to vegetation in the pool.

Visually striking, these eye-catching salamanders are grayish-black with two irregular rows of yellow or orange spots from head to tail. They range from 6 to 9 inches in length. This is an oddly patterned individual that I saw migrating last month.

Spotted Salamanders eat earthworms, snails, slugs, spiders, millipedes, centipedes, pillbugs and insects. In the wild, they typically live for about 20 years, though some have been reported to be as old as 30.

I look forward to seeing Spotted Salamanders each year; not only is it a chance to observe a large number of amphibians, but it is also a sign that a few months of nice weather is just around the corner.
