African fish, genus Polypterus, found
in tropical swamps and rivers. Cylindrical in
shape, some species grow to 70 cm/2.3 ft or
more. They show many `primitive' features,
such as breathing air by using the
swimbladder, having a spiral valve in the
intestine, having heavy bony scales, and
having a larva with external gills. These,
and the fleshy fins, lead some scientists to
think they are related to lungfish and
coelacanths.
