A profile of the Southeastern Slimy Salamander.
By Dick and Patti Bartlett
Plethodon grobmani, the Southeastern Slimy Salamander, is a creature of pinewoods habitats. It was once fairly common in our neighborhood. Today (2021) following several lengthy droughts and a major attack of pine bark beetles (and the resulting death of old pine stands), this salamander is almost unknown here. At the turn of the century I would go across the street, enter the pinewoods, and in a half hour search say “howdy-do” to about a dozen slimys. Compare that to my occasional searches over the last 10 years when my exact total was one—a single salamander-- and it was not in the best of shape. Of course, as already mentioned, most of the pine trees in that area are gone also, victims of the infestation of pine-bark beetles.
In other locales, where the pine bark beetle plague was less pronounced than here, this white-flecked black salamander remains easily found in pine and mixed woodlands. Like others of this, genus this salamander has no aquatic larval stage. The egg clutch is deposited in or beneath moist fallen pines and development, from the newly deposited eggs, through metamorphosis, to emergence as a miniature of the adults occurs in the egg capsule.

A Yellow Rat Snake from Central Florida .
By Dick and Patti Bartlett
Despite their need for papers and what the geneticists claim, I continue to follow the Linnaeus method and recognize subspecies. To that end, this is now and has been almost forever the Yellow Rat Snake, Pantherophis obsoleta quadrivittata. There are 4 other subspecies, including the nominate form, the northeastern Black Rat Snake, in this species group.
It is at the southeastern edge of its range that the Black Rat Snake slips gently into the yellow race. First the southernmost Black Rat Snakes assume a dorsolateral pattern of stripes and a greenish hue and as the greenish rats continue further south they become the traditional and long recognized yellow subspecies. But way south, down near Lake Okeechobee, when the Everglades was truly a river of grass, before the rice fields, the sugarcane, the sodfields, before the maze of drainage canals and Brazilian pepper, the yellow rat snake lost all but a vestige of stripes, assumed a deep orange color, and became the Everglades rat snake. Human influx = habitat destruction. And despite the efforts of the state, if such efforts, are actually real, habitat destruction continues, seemingly almost unabated.
But now back to comments regarding the yellow rat snake. They are real, and they continue to exist, perhaps in reduced numbers, over most if not all, of their long-described range. They remain rather common in our neighborhood, but houses are now quickly replacing the woodlands here. I can only hope for the best. Long live the Yellow Rat Snake.

This Gladiator Treefrog was sitting quietly in a low shrub.
By Dick and Patti Bartlett
This big brown(ish) treefrog is, at an adult length of 5 inches, one of the largest hylids from Amazonas to Panama. Although both genders attain this length, males often are marginally the larger. The unveined orangish eyes help differentiate this common treefrog from other large species. The sides and dorsum bear dark markings that may be prominent or almost invisible. All four feet are webbed.
The Giant Gladiator Treefrog ( Hyla ( Boana) boans), is commonly seen in riveredge/streamedge shrubs and low trees, and less commonly on the moist shoreline.
The name of Gladiator was given for males at their breeding sites will grapple in territorial battles. These scraps are made the more serious due to the fact that the males have sharp, bony, thumb excrescences. It is usually the bigger male that wins.
Nesting depressions may be either natural small shore-edge puddles or a depression dug by the male. There is usually at least a small water-holding connection to the nearby permanent water source. It is through this that the tadpoles reach the permanent water in which they grow and metamorphose.

The Mexican Hook-nosed Snake is a tiny burrowing species from South Texas and Mexico.
By Dick and Patti Bartlett
Oh, OK, so it’s not a hog-nosed snake, but in profile, its sharply upturned rostral scale, sure makes it look like one. This is the tiny Mexican Hook-nosed Snake, Ficimia streckeri. A true miniature, it is adult at from 7 to 11 inches, but may, on rare occasions reach a foot and a half in length. The few that I’ve seen (it was Kelly Irwin who introduced Patti and me to this snake) have been under a foot long. In the USA this species is restricted to southern TX, but its range extends far southward in eastern Mexico.
In keeping with its preference for soils, often near water sources, through which it can easily burrow, this is basically a sand-tan to pale brown or sand-gray(ish) snake with an unpatterned head and a busy pattern of narrow darker bars or spots along the back. The lower sides are basically unpatterned. This little snake can be easily differentiated from hog-nosed snakes, all of which have keeled scales, by its smooth (=unkeeled) body scales. It is usually crepuscular or nocturnal when surface active.
