Описание
[ редактировать ]
Рена Хумильс , как и большинство видов в семействе Leptotyphlopidae, напоминает длинный дождевой червя . Он живет под землей в норах , и, поскольку он не имеет никакого пользы для зрения, его глаза в основном рудиментарны . Западная слепая змея-это розовая, фиолетовая или серебристо-коричневая по цвету, блестящий, червячный, цилиндрический, тупой на обоих концах и имеет светлые черные глаза. Череп густой, чтобы разрешить закуривать, и в конце его хвоста есть позвоночник, который он использует для рычага. Обычно он составляет менее 30 см (12 дюймов) в общей длине (включенная в хвост), и он такой же тонкий, как и дождевой червя. Этот вид и другие слепые змеи являются люминесцентами при низкочастотном ультрафиолетовом свете ( черный свет ). [5]
On the top of the head, between the ocular scales, L. humilis has only one scale (L. dulcis has three scales).[6]
Common names
[edit]Common names for R. humilis include western slender blind snake, western threadsnake,[4] and western blind snake.
Geographic range
[edit]R. humilis is found in the southwestern United States and northern Mexico. In the US it ranges from southwestern and Trans-Pecos Texas west through southern and central Arizona, southern Nevada, southwestern Utah, and southern California. In Mexico its distribution includes the Mexican states of Baja California, Sonora, Sinaloa, Nayarit, Jalisco, Colima, Chihuahua, Durango, Coahuila, Tamaulipas, and San Luis Potosí.
The type locality given is "Valliecitas, Cal." The type locality was restricted by Klauber (1931) to "vicinity of Vallecito, eastern San Diego County, California," and by Brattstrom (1953) to "the Upper Sonoran Life Zone of the Vallecito area".[2]
Habitat and diet
[edit]Rena humilis lives underground, sometimes as deep as 20 metres (66 ft), and is known to invade ant and termite nests. Its diet is made up mostly of insects and their larvae and eggs. It is found in deserts and scrub where the soil is loose enough to work.
