The Male consciously
moves his belly,
which could be a stimulus
for the female to lay eggs
 or possible the male
is releasing sperm.
Soon, strongly and repeatedly
she arches her back,
signaling to the male
to dismount.
The egg laying process
is very fast,
which is not a common feature
in amphibians.
This is also a unique
breeding behavior
because at the time
of the egg laying
the males are not usually
on top of the females.
The number of eggs
varies with the size
of females.
In most amphibians
the males retain their position
at the same site 
and keep calling,
possibly to attract
another mate.
