I came across several of these cool creatures on my visit to Missouri last month. The Western Slimy Salamander is a black to blue-black, medium-sized woodland salamander with a long, rounded tail and numerous silvery flecks irregularly distributed over the head, back, limbs and tail.
This amphibian is in a group of some 13 closely related species called the Plethodon glutinosus complex; at one time these were all considered a single species, the Slimy Salamander. The Western Slimy Salamander is the only member of this group that occurs in Missouri.
They are most active on the surface during cooler, wet conditions in the Spring and Fall. During the hot Summer months they are difficult to find, since they retreat underground into cool, moist caves, or find damp places by burrowing into large piles of leaf litter.
Western Slimy Salamanders feed on a wide variety of arthropods, including ants, beetles, flies, worms insect larva and pill bugs. They can reach nearly 8 inches in total length, but most individuals vary from about 4 to 7 inches. Much of that length is because of its long tail.
This salamander has an interesting defense mechanism. When handled, it produces a thick, sticky substance from glands in its skin. The substance is not only extremely sticky, but is also very difficult to clean. This ploy prevents it from being eaten by snakes and other potential predators.
