Question

why the striders has dry capillary legs?​

Answer 1

ANSWER:  

Strider has dry capillary legs because they can walk in the water with the phenomena of surface tension which helps them to keep dry.  

EXPLANATION:

Strider legs have tiny hair, which helps them to repel water and produce an air gap between water surface and strider feet, which results in the founding of a tension between them, making a fragile tissue layer which helps strider to walk due to this surface tension.
