Rangifer Tarandus (Reindeer)

Classification Project Unit 3

Scientific Name

Reproduction

Reindeer Life Cycle

Reindeer are viviparous animals so they reproduce internally like most mammals. That isn't the only interesting thing though, for Reindeer it doesn't take very long to mate, this is because of their shorter mating season. This sometimes only takes up to ten days. This is done so that all females will have their young at around the same time. Reindeer use breeding as a defensive mechanism. They try for power in numbers so that more calves can live. A bigger group is harder for predators to attack.

In late September male Reindeer have to fight other males to mate. Typically two males lock their horns together and they begin to push against one another. The strongest and most powerful male can mate with 15 through 20 females. A young calf is normally born in May or June. After 45 days the calves can graze, but they continue to receive milk from their mother. This continues until Autumn when they leave their mothers and become self reliant.

Characteristics Of A Reindeer

Animal Cells vs Plant Cells

Adaptations

Reindeer have something called "nasal turbinate bones" which causes cold air coming in to be warmed by body heat and then it is entered into the system heating the Reindeer. Even the hooves of Reindeer change seasonally, in the summer they soften and during the winter they tighten. Their hooves tighten as the need for food grows as to make it easier to dig for lichen.

A Reindeer is a multicellular organism. This trait allows the organism to have such a mass, if not for being multicellular a Reindeer would be much smaller. Also being multicellular helps with something call "Cell Differentiation" which pretty much means having cells for specific functions such as producing energy.

Envoirment

Source Of Energy

Reindeer benefit from the cold weather which keeps away insects such as mosquitoes. Their hooves allow them to dig for food which other animals are not capable of reaching. They actually benefit from cold air with their noses which turns cold air into warm air. They have everything they need to thrive in their environment.

Once the snow covers the Tundra Reindeer must resort to one food. Lichen are capable of surviving the harsh winter because of their biological combination of algae and fungus. This composition means Lichen don't need much sunlight to survive. They find Lichen by digging it out of the snow. They also sometimes eat lemmings and other sorts of grasses or leaves. This diet is they way it is because Reindeer are ruminant which means they have a four chambered stomach.

Due to the flexible movement a Reindeer

possesses it has been claimed and proven

that Reindeer have Animal Cells. Plant cells

would typically restrict movement because

of their durable cell wall. Animal Cells

lack a cell wall and only rely on the cell

membrane. This allows more dynamic

movement.
