Why are snails on cactus?

Snails are often found on cacti because they seek moisture and shelter in the harsh desert environment. Cacti provide a unique habitat with their thick, fleshy tissues that can retain water, which is crucial for snails' survival. Additionally, the surfaces of cacti can offer food sources like decaying plant matter or algae, attracting snails. The protective spines of cacti may also deter some predators, making it a safer place for snails to reside.
