How does the tarantulas physical structurre help it to stay afloat?

Tarantulas have a unique physical structure that aids in their buoyancy, primarily due to their lightweight, hairy exoskeleton. The fine hairs, or setae, on their body create surface tension, allowing them to stay afloat on water. Additionally, their body shape and distribution of mass help to prevent sinking, enabling them to traverse water surfaces more effectively. This adaptation is particularly useful for escaping predators or moving between habitats.
