Question

Some lizards are able to absorb moisture from their surroundings through what process?

Answer 1

Special skin structures, comprising a micro-structured surface with capillary channels enable the lizard to collect water by capillarity and transport it to the mouth for ingestion.

Explanation:

Technically, from a physics or chemistry perspective, that is a collection mechanism, and not really an "absorption" mechanism. True absorption through skin would be a diffusion process across a membrane.

Special skin structures, comprising a micro-structured surface with capillary channels in between imbricate overlapping scales, enable the lizard to collect water by capillarity and transport it to the mouth for ingestion.
