Take the little puffer fish, for exam- ple, which has attracted the attention of scientists from earliest times on account of its shrewd hab- it of defending itself by infla- tion.

The puffers arc of many species, many of them reaching a length of about two feet, most of the larger kinds being found onK in the large ri\iTs of the trojiics.
When caught n nets and dragged ashore they inflate t h e m s e 1 \' e s with air just as with water when in the sea, making a slight sucking sound until their skins are as tight as drums. They remain inflated until thrown back into the water and can be knocked about on the beach like rub- ber balls with- out a particle of air escaping.
