What type animal is a leech?

Answer 1

Leeches are animals, and invertebrates. they are also parasites because they feed by drinking the blood of other creatures without killing them.

[Correction] No. Leeches are not parasites. Like mosquitos, they are considered predatory rather than parasitic. I guess it's an easy mistake to make, just like how people say snakes are poisonous even though no snakes are poisonous. Poisonous means that you either inhale or ingest poison. Snakes are venomous. Venom is injected.

Answer 2

Leeches belong to the Phylum Annelida, Class Hirudinea. There are three sub-classes: Branchiobdellida, Acanthobdellida and Euhirudinea. The sub-class Euhirudinea consists of two orders: Rhynchobdellida, which have an eversible proboscis, contain blood vessels and often lay large yolky eggs; and Arhynchobdellida, which have a non-eversible pharynx often bearing jaws, they lack blood vessels and lay small eggs.

The medicinal leeches (Hirudo medicinalis) are members of the order Arhynchobdellida.
