Button Isopod:
South Africa,
aquatic, feeds
on algae
        Order Isopoda
• Around 4,500 species of isopods
  are found in marine environments,
  mostly on the sea floor. Some 500
  species are found in fresh water;
  and another 5,000 species are the
  woodlice in the suborder
  Oniscidea, which are thus by far
  the most successful group of
  terrestrial crustaceans
               Order Isopoda
• Range in length from .5mm to 500mm



Californian tongue-
eating isopod: rose
snapper parasite,
chews off tongue,
hooks specialized
pleopods to nub,
serves as a
mechanical
replacement.
           Order Isopoda
Horned Isopod:
  South Africa, lives
  on rocky shores
  eats kelp and
  algae as well as
  live prey and
  carrion.
