9. Aquatic Adaptations
Previously unidentified aquatic adaptations have been found by new studies that make capybaras quite fit for their semi-aquatic way of existence. Studies have discovered specific muscle structures and bone density patterns that improve swimming efficiency while preserving agility on land. High on their heads, their eyes, hearing, and nose let them remain mostly submerged yet still aware of their environment. Scientists have found unusual respiratory system adaptations allowing them to hold their breath for long stretches of time, and their skin features specialised glands offering defence against aquatic infections.
