-- the foam-nesting frogs
Around seven genera of Asian and
African frog species belong to this family, which is considered
a subfamily of the Ranidae by some. The typical breeding mode
is the construction of foam "nests" situated above
water. The Madagascan genera Boophis and Aglyptodactylus
lay their eggs directly in water. Some members of the Asian genus
Rhacophorus have long, fully webbed toes, with which they
can glide from one tree to the next.
Blue-Legged Tree Frog (Rhacophorus
A common species
acoss most of southeast Asia, the three-inch long blue-legged
tree frog occurs in a variety of habitats and is often encountered
in cities where it can be observed feeding on insects attracted
by electric lights. Very much aboreal in habits, this frog is
a typical member of its family and breeds in the standard fashion,
the male and female using their arms to whip their spawn into
a merangue-like "nest" which they position over water.
In urban situations, a man-made water supply is often used. This
foam nesting behavior is shared by a number of unrelated groups,
and serves to keep the eggs from being vulnerable to egg-eating
