Here's a preview of my next set, "Nature's Wonders Salamanders & Newts". It's funny how I chose to do this set. I wanted to do another NW set and looked at the fauna categories, I already had. The amphibian section looked pretty lonely with only "Frogs" in it, so I decided to see what other amphibians I could create to give the frogs some company. It turns out there isn't too much else; Salamanders & Newts and Caecilians (blind worms). One interesting thing I learned about Salamanders & Newts is that they're all poisonous, much like poison dart frogs, ranging from giving off a mild skin irritant to deadly (puffer-fish) poisonous. The Fire Salamander is one of the most common species of salamander found in Europe, and are found in most of southern and central Europe. They are most commonly found at altitudes between 250 meters (820 ft) and 1,000 meters (3,300 ft). They live in the forests of central Europe and are more common in hilly areas. They prefer deciduous forests since they like to hide in fallen leaves and around mossy tree trunks. They need small brooks or ponds with clean water in their habitat for the development of the larvae. Whether on land or in water, fire salamanders are inconspicuous. They spend much of their time hidden under wood or other objects. They are active in the evening and the night, but on rainy days they are active in the daytime as well. The diet of the fire salamander consists of various insects, spiders, millipedes, centipedes, earthworms and slugs, but they also occasionally eat newts and young frogs. Despite its wide distribution and abundance, it is classified as Vulnerable on the IUCN Red List due to its susceptibility to infection by the introduced fungus Batrachochytrium salamandrivorans, which has caused severe declines in fire salamanders in parts of its range. The fire salamander's primary alkaloid toxin, samandarin, causes strong muscle convulsions and hypertension combined with hyperventilation in all vertebrates. The poison glands of the fire salamander are concentrated in certain areas of the body, especially around the head and the dorsal skin surface. The colored portions of the animal's skin usually coincide with these glands. Compounds in the skin secretions may be effective against bacterial and fungal infections of the epidermis; some are potentially dangerous to human life.
