An excellent animation film in biology
(mp4 film) The exceptional
life span of the hydra (in English).
The hydra is a little (about 15mm in length) and fairly primitive
animal which lives in fresh water. Similarly to
some other animals
(e.g. worms) but to a greater degree, it has a regenerative capacity
which means that if it is cut into two parts
two complete organisms will be reconstituted.
This ability gives it a life span of
several years that is to say much longer than other animals
of that size. Needless to say, it may not be the only
organism possessing this property.
The present animation was made by Robert Krulwich and it is
available on several websites.
Another example of an interesting scientific animation film
is the following.
``The Higgs Boson Simplified Through Animation''
by Wyatt Johnson.
