Requirements to be a Mammal

  • Have bilateral symmetry
  • Feeders/Eaters: Herbivores, Carnivores, Omnivores, & Insectivores.
  • Physical Features:
  1. Are vertebrates (which means they have a backbone or a spine ).
  2. Are endothermic. Also known as “,” endothermic animals regulate their own body temperate which allows them to live in almost every climate on Earth.
  3. Have hair on their bodies.
  4. Produce milk to feed their babies. This allows them to spend more time with their young and teach them important skills they need to survive on their own.

Mountain Pygmy Possum

1) Body length: 10 to 13 cm

Tail length: 13 to 16 cm

Weight: 30 to 60 g


2) During the winter, the Mountain Pygmy Possum hibernates under the snow. They don't sleep for the whole winter, though. They sleep for a few days and then wake up to eat the food, such as tree fruit, that they have collected in advance.

Slow Loris

1) Loris is the only known "poisonous" primate. It has a patch filled with venom under its elbow used for protection against the predators. When faced with danger, loris licks its elbow and covers its teeth with poison. As soon as the Loris bites its enemy, it will deliver the venom.


2) Loris has very strong grip. It can hang from the branch, attached by its feet for hours when it uses both hands for feeding.

The Fossa

1) Fossa's communicate largely through scent glands. Both males and females occupy territories that they scent mark with secretions from glands on their chests and under the base of their tails. Fossa's mark rocks, trees, and the ground to communicate and keep track of each other. Their glands also release a pungent smell when the animal is irritated or frightened.


2)Female Fossa's are temporarily masculine. The female Fossa undergoes a strange development stage during adolescence known as transient masculinization unique to Fossa's she develops certain male parts. Adult females lack these features. Its unclear what purpose this transient masculinization serves, but scientists hypothesize that it protects juvenile females from either sexual harassment by adult males or aggression from territorial females.
