Study Notes

Mammals' Swimming Abilities

Moose can swim up to 20 kilometers, fully submerging themselves in the water, thanks to their unique adaptation of a long, flappy snout that acts as a valve to keep water out of their nostrils.
Moose swim to feed on plants high in salt, essential for their growth and antler development.

Elephants' Swimming Abilities

Elephants are good swimmers, using a lunging-style to propel themselves through the water, and their trunks as snorkels.
Their size and body shape help them float, displacing a large amount of water, and their large lungs reduce fatigue while swimming.
The gas in their stomachs from plant digestion inflates them, making them more buoyant, and their skull bones have holes, making them slightly lighter.

Armadillos' Swimming Abilities

Armadillos can swim up to 50 meters, despite their appearance, using a unique technique of gulping air to inflate their stomach and small intestine, making them more buoyant.
They can also run along the bottom of shallow water, using their powerful claws.

Camels' Swimming Abilities

The Kharai camel breed can swim up to 3 kilometers in search of salty plants, and their name "Kharai" comes from the local word for "salty" or "saline".
Historically, camels may have been more aquatic, but were domesticated for their milk and as draft animals, leading to a loss of their swimming abilities.

Kangaroos' Swimming Abilities

Kangaroos are good swimmers, using their powerful legs to tread water and stay buoyant, with a unique technique of alternating their kicks, unlike their movement on land.
They can swim at a speed of about 1 meter per second, and may have developed this ability to cross rivers or escape predators.

Sloths' Swimming Abilities

Sloths can swim three times faster than they can walk, despite their slow movement on land, using their long arms to spread out their back legs for balance and buoyancy.
Their slow digestion means gas builds up in their stomachs, making them more buoyant, and they can hold their breath for over 20 minutes.
They may have inherited their swimming abilities from their semi-aquatic ancestors.

Proboscis Monkeys' Swimming Abilities

Proboscis monkeys are excellent swimmers, and can dive into rivers from high up in trees, swimming for nearly half an hour.
They have a unique strategy of doing cannonballs into the water to scare off predators like crocodiles.
They have webbing at the base of their fingers and toes, which adds power to their strokes, and may have developed this ability to escape predators and find food in their mangrove habitats.
