Give the Structural and functional adaptation of leeches for obtaining the food?
Structurally, leeches have a muscular, tube-like body with a sucker at each end to attach to a host. Their mouth contains three sets of jaws with sharp teeth to pierce the skin of the host to suck blood. Functionally, leeches secrete hirudin, an anticoagulant, to prevent blood from clotting while they feed, allowing them to obtain a blood meal successfully.
What is the support system of leech?
Leeches have a support system that includes their muscular body structure and the presence of suction cups on their undersides.

Some parasitic leeches are attracted by warmth What type of host would you expect such leeches to have and what would be the adaptive advantage of this attraction?
Leeches attracted to warmth are likely to parasitize warm-blooded hosts, such as mammals. The adaptive advantage of this attraction is that warm-blooded hosts provide a stable environment with a constant temperature that helps leeches maintain their metabolic activities and ensures a steady food supply.
Do leeches drink human blood or do they just bite them and make them bleed?
Leeches drink human blood by attaching themselves to the skin of their host and using their jaw and saliva to create a wound from which they can feed. They release an anticoagulant in their saliva to prevent the blood from clotting, allowing them to feed more easily.
How do Leeches eat?
Many leeches have a proboscis used for swallowing the prey or for sucking its fluids; others have jaws for biting. Many parasitic leeches are able to parasitize a wide variety of hosts. Most of the marine and some of the freshwater leeches are fish parasites. The medicinal leech, Hirudo medicinalis, is one of a group of aquatic bloodsucking leeches with jaws. Another group of jawed bloodsuckers is terrestrial; these leeches live in damp tropical vegetation and drop onto their mammalian prey. Most parasitic leeches attach to the host only while feeding; a single meal may be 5 or 10 times the weight of the leech and provide it with food for several months. The digestive tract of bloodsuckers produces an anticoagulant, hirudin, which keeps the engorged blood from clotting. A few leeches attach permanently to the host, leaving only to reproduce.
How does leech eat?
Leeches drink the host's blood.
