While reptile scales use a sophisticated naming system (see figures), there has been a certain confusion because of synonymous names. For instance, the ventral scales are often called ventrals but gastrosteges is common in the older literature. In more recent publications they are often abbreviated as VSR (for ventral scale rows) or simply V. [4]
The scales of a snake primarily serve to reduce friction as it moves, since friction is the major source of energy loss in snake locomotion. Rainbow boas get their name from the coloration of their scales caused by iridescence.
Reptile scale types include: cycloid, granular (which appear bumpy), and keeled (which have a center ridge). Scales usually vary in size, the stouter, larger scales cover parts that are often exposed to physical stress (usually the feet, tail and head), while scales are small around the joints for flexibility.
Water collection has been shown in some rattlesnakes, though the nanostructure of the scales is thought to be more significant than the macrostructure (keel) of the scales. [6] In some viperines, most notably those of the genus Echis, the lateral scales are not only keeled, but the keels have minute serrations. The snakes use this in a warning ...
In snakes, the ventral scales or gastrosteges are the enlarged and transversely elongated scales that extend down the underside of the body from the neck to the anal scale. When counting them, the first is the anteriormost ventral scale that contacts the paraventral (lowermost) row of dorsal scales on either side. The anal scale is not counted. [1]
Staff at London Zoo got the measure of giant gorillas, plump penguins and skinny stick insects at the zoo’s annual animal weigh-in on Thursday. Zookeepers tempted squirrel monkeys onto scales ...
During the Vietnam War, American soldiers referred to the many-banded krait as the "two-step snake," in the mistaken belief that its venom was lethal enough to kill within two steps. [26] The many-banded krait gathered worldwide attention after a juvenile individual bit Joe Slowinski on 11 September 2001 in Myanmar. He died the following day ...
The labial scales are the scales of snakes and other scaled reptiles that border the mouth opening. These do not include the median scales on the upper and lower jaws [1] (rostral and mental scales). The term labial originates from Labium (Latin for "lip"), which refers to any lip-like structure. In snakes, there are two different types of ...
