Leech is ………. belonging to phylum annelidaA. CarnivorousB. CoprophagousC. HerbivorousD. Sanguivorous

The correct answer is D. Sanguivorous.
• A leech is an invertebrate animal belonging to the phylum Annelida and the subclass Hirudinea.
• Many species of leeches are sanguivorous, meaning they feed on the blood of other animals.
Feeding Behavior:
1. Sanguivorous Nature:
o Sanguivorous leeches attach to the host's skin using their sucker-like structures.
o They secrete an anticoagulant called hirudin, which prevents the blood from clotting, allowing them to feed easily.
o Examples: The medicinal leech (Hirudo medicinalis) is a well-known sanguivorous species.
2. Other Feeding Types in Leeches:
o While most leeches are sanguivorous, some are carnivorous, preying on small invertebrates, but this is less common.
Why the Other Options Are Incorrect:
1. A. Carnivorous:
o Some leeches are carnivorous, but the most commonly known leeches, including those used in medicine, are sanguivorous.
2. B. Coprophagous:
o This term refers to feeding on fecal matter, which is not characteristic of leeches.
3. C. Herbivorous:
o Herbivory involves feeding on plants, and leeches do not have this diet.
Leeches, particularly those used in medical settings, are primarily sanguivorous (blood-feeding), making D the correct answer.
