Question

How do spiders digest their food?

Answer 1

Spiders are the only animals that digest their food outside their bodies. After their prey is captured, spiders expel digestive enzymes from their intestinal tract onto the victim. The enzymes break down its body tissues and, after a few seconds, the spider sucks up the predigested, liquid tissues. By repeating this process several times, spiders digest the entire animal. Spiders have a sucking stomach that is the main pump for drawing food into the body. Food is rapidly ingested due to the wavelike contractions of muscles that surround the stomach and of muscles that attach to the body wall.
