What is the mode of nutrition in leech?

Leeches primarily exhibit a carnivorous mode of nutrition, feeding on the blood of various hosts, including fish and mammals. They possess specialized jaws to pierce the skin of their prey and secrete anticoagulants to facilitate blood feeding. Some leech species also engage in detritivory, consuming decaying organic matter and small invertebrates. Overall, their nutritional habits vary depending on the species and environmental conditions.
