Giraffe Adaptations and Behavior

The video explores how Kalahari plants and animals, particularly giraffes, adapt to their environment. Giraffes have evolved long necks not only for feeding at heights but also for thermoregulation. They possess a network of blood vessels under their skin that helps dissipate heat. Additionally, giraffes engage in a behavior called necking, where males fight for dominance using their necks and reinforced skulls to avoid injury.

What advantage does a giraffe's long neck provide in terms of feeding?

• It allows them to run faster.

• It allows them to reach leaves at the top of trees.

• It helps them dig for roots.

• It enables them to swim better.

Besides reaching high foliage, what is another reason for the evolution of a giraffe's long neck?

• To help them fly.

• To store water.

• To dig burrows.

• To keep cool under the sun.

How do giraffes primarily release heat from their bodies?

• Through their ears.

• Via thermal windows in their patches.

• By sweating profusely.

• By panting.

What is the relationship between the size of a giraffe's neck and its cooling ability?

• A larger neck has fewer thermal patches.

• A larger neck has more thermal patches.

• A larger neck has no thermal patches.

• A larger neck has the same number of thermal patches.

What is the purpose of the ritual called necking among giraffes?

• To migrate.

• To establish dominance.

• To attract mates.

• To find food.

How do giraffes avoid concussions during necking?

• By wearing helmets.

• By using their tails for balance.

• By having a reinforced skull.

• By avoiding head contact.

What physical change occurs in older bulls due to necking?

• They develop longer tails.

• They grow larger ears.

• They lose their horns.

• They develop calcified growths on their foreheads.
