Springtails are all around us.
Springtails (Collembola) are hexapods but not insects, being members of the insects’ sister class Entognatha (which also includes proturans and diplurans). They are tiny (<6mm), and numerous, occurring at densities up to around 100,000 per square meter of topsoil. They are important components of forest floor ecosystems, and some species can also be found floating on the surface of stagnant water. Continue reading “Meet the Springtail”
The olm is the only species in the genus Proteus within the Proteidae family (the other genus is Necturus). Olms are cave salamanders found in Southern Europe. Like many other derived groups of salamanders the males courts the females before depositing a spermatophore for her to pick up with her cloaca. Fertilization is internal in the olm.

Seriously this cat is incredible and adorable. The margay (Leopardus wiedii) is a bit like a mini ocelot. They are native to the Americas and there is even a record of one found in Texas over 100 years ago!
These cats are nocturnal and live primary in the rainforests from Argentina all the way to Mexico. They are absolutely striking and unfortunately this has made the margay a target for fur poachers resulting in their IUCN status as near threatened.
Most amazingly, the margay can rotate its ankle 180 degrees to climb trees upside down. 
The picture to the right cannot do the ankle rotation move justice (watch the video 1:23!). They can climb down trees head first and may even nap upside down. Margays can hang from a branch upside down by a single paw. The video below is absolutely gorgeous and worth the time to watch (full screen).

The Texas Blind Salamander (Eurycea rathbuni) is in the Plethodontidae family, also known as lungless salamanders. There are over 400 species of plethodontids making them the most speciose family of salamanders. These salamanders have elaborate and stereotyped courtship rituals. Research has suggested that in general, the male initiates the mating ritual in salamanders. While research and data are sparse for Texas Blind Salamander, it has been reported in captivity that the female actually initiates the courtship behavior.
The female has been reported to rub her nose on the dorsum and side of the male near the cloacal region. Next, the female was observed to rub her cloacal region against the rocks on the bottom of the tank nearby the male. The nearby male began to show interest at this point and courtship ensued. The courtship sequence proceeded with the male depositing a spermatophore, leading the female, and finally the female’s cloaca aligned over the spermatophore to pick it up.
This courtship behavior account comes from a lovely paper in 1988 by Bechler in The Southwestern Naturalist.

The Texas Blind Salamander (Eurycea rathbuni) is a cave salamander that has adapted to life living in the dark. With extremely underdeveloped eyes, unpigmented skin, and the retention of its juvenile aquatic form, this salamander is perfectly suited to live in the underground cave streams. Found only in caves around San Marcos, Texas these salamanders are actually considered endangered on the State level. Because they live only in specific areas and rely on the Edwards aquifer, the Texas blind salamander is extremely susceptible to changes in water quality. Their size reaches between 3 and 5 inches and they eat a diet of most aquatic invertebrates. Continue reading “Meet the Texas Blind Salamander”
