Transcript of Polar Bears!

Behavioral Adaptions!

Polar bears adapt to the environment by:
-hibernating
-protecting themselves against other animals
-catching food
-Migration
And shelter.

They need these things to adapt o the harsh arctic environment that they live in.

Polar Bears!
What are the behavioral adaptations and adaptions,rhythmic activities, feeding behaviours; communication; social and territorial behaviours; homeostasis and maintenance of polar bears? Lets take a look...
Rhythmic Activities!
Feeding behaviors
When polar bears hunt, they stalk thier prey. For example, when the stalk the ringed seals, they wait for them to rise to catch thier breath, then attack. This is called seal stalking. They then eat the seal.
Communication
Polar bears make little communication. But when they do there are specialised sounds. Like, if a adult polar bear is agitated, it will hiss, growl, chuff sounds like that.
Cubs are a little different, they will smack their lips whimper and squeal.
They also communicate through sight, smell and touch.
Polar bears may be active in the day or the night.
This activity depends on their prey. The times they are active, that is when the polar bear will be. This way they get maximum feeding opportunities. In saying this, they are mostly daytime animals because that is when seals are active.

social and territorial behaviors
Polar bears are not very territorial at all, they will protect thier cubs, but because they migrate so much, they don't have land they need to protect. Polar bears usally travel alone unless they are seeking a mate.
Homeostasis
Polar bears use their thick white fur to keep their body warm from the cold elements of the arctic. They also have a thick layer of fat that helps insulate it. It is easy for them to over heat they are so warm.
Maintenance
Polar bears maintain their body temperature by moving slow to avoid over heating.
