Question

Leeches are present where the surrounding was moist why

Answer 1

Answer:

While a few leeches can be found in oceans or moist soil on land, most leeches prefer to live in shallow bodies of fresh water. If you find a leech attached to your body after a swim, don't panic. Most leech bites are not harmful. As with any bite, there's a chance of infection or an allergic reaction.
