Snake-tailed Fringe-toed Lizard - Quraish
Whilst birding recently in the Tanoumah
area I came across a Snake-tailed Fringe-toed Lizard Acanthodactylus opheodurus down a tree filled wadi. The lizards
were very active even during the hottest part of the day and where always found
near small low-lying plants with hard sandy soil. It is superficially similar
to its larger congener Acanthodactylus
boskianus, and was described officially in 1980. As its name suggests, this
species has a particularly long tail and, in common with other Acanthodactylus species, the toes are
fringed with scales adapted for running over loose sand. Like other lacertids,
the body is long and cylindrical, and the legs are well developed, with the
animal having a basic body colour of grey, with seven dark stripes running down
the back and sides and a tail tinged red in immatures. They live in a range of
arid habitats, including plains with relatively hard sand cover and low hills
covered by dense bushes. It is a diurnal lizard and lives in burrows excavated
out of hard sand where it remains concealed for all but a few hours of the day.
Their burrows not only act as a shelter from predators but also provide refuge
from extreme temperatures. The snake-tailed fringe-toed lizard is currently known
from the Arabian Peninsula and several other countries in the Middle East,
including Jordan, Kuwait and Iraq.
