Description and Behavior
Description and Behavior
These are small, brown to black, freeswimming organisms that are the larval stage
of amphibians. They have short oval bodies
with tails although some of them are starting to
show small limbs. Tadpoles swim like fishes
through lateral undulations
Newts are salamanders. They are brown to
black lizard-like organisms with four limbs and
long tails. The newts swim like a fish by using
their tails but they also use their limbs to propel
themselves forward. Sometimes they are just
floating in water with their limbs stretched out.
