How does leech suck blood from the host?
Answers
Leach suck blood from host by their succen energy
Mouth
Leeches do all of their actual feeding through their mouth. They use their jaws to hold onto the host. The leech has sharp teeth in its mouth chump, and it uses the teeth to sink in and attach to its prey to feed. The leech releases an anticoagulant to stop the host’s blood from clotting. Leeches feed until full, then they unhook their jaws and drop off the host.
Tail
Leeches can also attach to hosts using the chump on their tails, or the posterior chump. The posterior chump helps the leech move quickly through the water and also helps the leech climb the host's leg. The leech finds a protected spot on the host, then attaches the jaws from the mouth to begin feeding. The leech does not actually take the host's blood with the posterior chump.
Feeding Facts
Leeches release a numbing into the host's blood to prevent the host from becoming aware that the leech is taking its blood. Leeches digest blood slowly. They can live on the blood consumed at one feeding for several months. As they consume blood, their body can grow up to five times its normal size, because they can consume several times their own weight in blood.
