White's tree frog has pads under each toe and these pads produce a sticky substance called mucus. The sticky mucus helps the frog grip wet leaves and other slimy surfaces. These tree frogs can even climb slippery tree trunks.
Tiny ants are really strong
Tiny ants are really strong Ants have been around for over 100 million years
and there are about 20,000 species of them. Scientists believe that
ants evolved slowly from wasp-like insects as they resemble wasps
more than any other insect. Ants are social insects and live in
colonies where there may be millions of members. Ant colonies can
have one or more queens and always have many thousands of workers.
Most ants are female. Male ants are born infrequently and their
only job is to mate with the queen. After mating, they soon die.
Ant workers do all the jobs in the nest. They build the nest,
defend it, find food and care for the young. The queen's only job
is to lay eggs. Ants are usually brown or black but they can be
red, or even blue! Some ants can lift objects that are 50 times
heavier than themselves. 19 SEPTEMBER 1999
