Frog
haven found in Sri Lanka
- More than 100 new frog species have
been discovered in the Sri Lankan rainforest.
[bbc news] |
Frogs are one of the most fascinating species
on this planet. They come in many shapes,
sizes, colours and patterns. Each frog species
has different behaviours, living environments,
feeding habits and defenses.
What
is a frog?
Frogs and toads are amphibians. Amphibian
means 'dual-life'. This refers to the 2
stages most frogs go through, firstly as
aquatic tadpoles then metamorphosing in
to air breathing land animals. Other amphibians
include salamanders and newts.
Frogs and toads belong to the amphibian
order 'Anura'. This means 'without tail'.
All frogs have no tail apart from the tailed
frog which does have a very small apendage
that it retains throughout life. With frogs
there always is en exception to the rule.
There are over 4000 species in the order
anura, but nobody knows exactly how many
different frogs and toads there are. New
species are being discovered at over 12
a year. It seems that this rate will carry
on as long as the frogs natural habitats
aren't destroyed.
These species are grouped into over 20
families.
