Armadillo

• Armadillos are very timid animals.
• They can jump over 3 feet straight up in the air.
  
• They are often run over by cars.
• Armadillos have a carapace, much like turtles.
• It covers most of the body.
• It is made up of bony plates covered with
  epidermal scales.
• This covering varies from a complete protective
  covering when animals roll into a ball, to a more
  loose-fitting one that does not completely cover.
  
• The carapace is attached to the skeleton by
  muscles and ligaments.
• It is not directly attached to the skeleton.

Armadillo

• Armadillos have very sparse hair.
• They do have teeth, but have no incisors or
  canines.
• Their teeth are shaped like cylinders and they do
  not have any roots.
• Most armadillos are terrestrial and are very
  well-equipped for digging.
• They eat insects and insect larvae.
• Occasionally, they will eat plants, eggs, or
  fruit.

5
Sloth

• There are 2 families of sloth 3-toed and
  2-toed. Characteristics are very similar for both
  families.
• Sloths are arboreal.
• This means they are tree-dwellers and have great
  difficulty moving on the ground.
• They often move upside-down on the underside of
  branches.
• They are nocturnal and sleep about 15 hours a
  day.

Sloth

• Sloths are very long-limbed.
• Their forelimbs are longer than their hindlimbs.
• Sloths are also syndactyl, which means that their
  toes are fused together.
• Their cervical vertebrae vary in number, from
  6-9.
• Sloths do have teeth, but no incisors or canines.
  
• The teeth are shaped like cylinders, have no
  roots, and are homodontic.
• Sloths have long, coarse hair on which blue-green
  algae grows.

  and fruit.

  poor temperature regulation.
