Lancing Nature | Annelids | Earthworms & Leeches

Annelids are segmented worms, ranging from the vital earthworms in our garden soil to the predatory leeches found in our local ditches. Both play critical roles in the Lancing ecosystem.

Horse Leech

A large, dark predator often found in damp drainage ditches. Unlike the medicinal leech, it does not suck blood but swallows small invertebrates whole.
