The hobbyist favorite, the colorful South African coral cobra.
Of the 3 subspecies of this interesting, 23 to 30 inch long, burrowing, elapine snake, it is the most brightly colored, southernmost, race, the Cape coral cobra, Aspidelaps l. lubricus, that is the hobbyist favorite.
A snake of arid habitats of the Cape region of South Africa and southern Namibia, when young this narrow-hooded cobra relative is clad dorsally and laterally in broad red and, except for the broad black nuchal marking, narrow black rings. When its anterior is elevated in the defensive posture, 2 or 3 broad black bands are displayed across its white throat and anterior venter. The red body rings are brightest dorsally and may fade noticeably on the sides. As the snake grows and ages the rings tend to break and become incomplete ventrally. The triangular nose-tip rostral scale is noticeably enlarged and helps this little snake with its burrowing proclivities. In nature it crepuscular and nocturnal and is often found beneath rocks.
The 2 more northerly forms, A. l. cowelsi of central Namibia and A. l. infuscatus (this latter being of questionable validity) of northern Namibia and southern Angola, are duller in color and may attain a slightly larger size. They are only marginally differentiated from each other, the former having a dark head and the latter having a light head, and are best identified by range.
Captives are easily maintained and, if cooled slightly in winter breed readily Frozen/thawed mice of suitable size are usually hungrily accepted as are various lizards. A clutch may contain from 4 to 8 (rarely a few more) eggs.
No matter how long they are captive, the coral cobras usually retain a feisty disposition, huffing, puffing, and occasionally striking at any and all disturbances.
Human deaths have been caused by bites from this small snake. The venom is neurotoxic. Extreme care should be used at all times.

Most of the western slender glass lizards that we found were between 16 and 22 inches in total length.
Last summer Jake and I spent a few days in Kansas looking for western massasaugas and Plains hog-nosed snakes. We succeeded admirably on the rattler (learning in the process that the Kansas examples are as fast as the proverbial greased lightning and very quick to take fright) but failed on the hoggy.
But while we were busily failing on Heterodon we began taking note of the number of western slender glass lizards, Ophisaurus a. attenuatus that we saw. Not only were the anguids present but they were present in numbers, and in huge numbers at that. As the sun was dipping low in the west or, if you prefer, as the earth was spinning rapidly eastward, we would see first one, then another, then 3 or 4 more, all subadults, of this pretty, prominently striped, lizard. By the time we acknowledged failure with the hognose each night we would have seen 10 to 20 glass lizards. While the western slender glass lizard was no stranger to me, at no other place had I seen them in such numbers.
And of at least as much interest as the mere presence of the lizards was the fact that almost all had a full, original tail. Kansas! For me the state itself and remembrances of western slender glass lizards will be forever intertwined.

I actually successfully bred this male South Florida mole king with a smaller female--both commercially obtained.
Dratted snake! How many times—how many years—how many pure thoughts—does it take to find a live one? I’ve tried over and over and over again— and then tried again--alone and with Jake. Sum total? Zero alive!
Other friends have found this elusive snake, and acquaintances have found even more. But my total--1, found years ago as road jerky over near Okeechobee City. And that doesn’t count in my book. So, other than a tale of failure, what is the story here?
Well, here it is in shortened format: After Price described this snake (Price, R.M. 1987. Disjunct occurrence of mole snakes in Peninsular Florida, and the description of a new subspecies of Lampropeltis calligaster. Bull. Chicago Herpetol. Soc. 22 (9): 148) the “lamprophiles of which I am not one, began flocking to South Florida (shades of L. alterna!) looking hard for the mole king.
Some succeeded, many (me included) failed. But I did continue to look occasionally, and did so throughout the described range of the subspecies. It was early on that I found the DOR and began to note that even though infrequently seen the snake was collected by others for the pet trade. So, wanting to actually see one in the wild, I began looking a little more frequently. I found garter snakes, water snakes and rat snakes galore, and even an occasional Florida king, but not a single mole king. I got so used to failure that when friends found one, I sulked. Yes, I sulked, and I’m not even fond of kingsnakes of any flavor. But I’m even less fond of perpetual failure.
So I stopped looking, and did so just in time, because the genetic wizards have just elevated it from subspecies status to a full species, and there’s no sense in wasting more time looking for a subspecies when I could be wasting it looking for a full species!
OK, Jake. No more procrastination. It’s time to find one of these durn things. South Florida, here we come!

The longitudinally divided dorsal stripe of the juvenile Scott Bar salamander is easily seen here.
The Scott Bar salamander ( Plethodon asupak) is a species of salamander in the family Plethodontidae. The genus occurs primarily in the USA but a few species extend northward into southern Canada. The Scott Bar salamander is restricted to a very small range in the Scott River drainage in Siskiyou County, California, at altitudes between 2,300 and 4,300 ft. Described in 2005, it is one of the most recently recognized species in the genus.
About half of the Scott Bar salamanders 5 inch length is tail. Males seem marginally the smaller gender. Juveniles are often more brightly colored than the adults, having a well defined red dorsum that is divided lengthwise by an ill-defined brownish stripe. Old adults often lack even vestiges of red, being an overall white-flecked gray. The flecking is most profuse laterally and the ground color is darkest ventrally.
Within its preferred habitat of rocky montane, evergreen clad, slopes, this can, within its limited range, be an abundant species, and on foggy or dew-spangled nights a fair number may be seen foraging. In this behavior they are identical to many (if not most) of the more widespread woodland salamanders.
