Mother leeches lay eggs in a cocoon from which baby leeches hatch. Baby Leeches are born with 32 brains and ten stomachs, and they live independently after their first meal. Baby leeches stay attached to their host until they find another host to feed on. Usually, they find hosts easily.

What Baby Leeches Look Like?

Baby leeches are thin like a needle, segmented worms, and are only a few centimeters long. They range in dark-hued colors from green and black to dark brown. Their body surface can be smooth or with lines and spots on them. The main external body parts are; a small head with a suckered mouth, body sediments throughout the central body, and a posterior sucker. They have segmented bodies, and the number of segments stays the same throughout their lives. They usually have 34 segments in their body.

Their slimy, smooth, and slippery appearing bodies have suction cups (suckers) on the end of their body. Baby leeches have three jaws and 50 to 60 piercing sharp teeth on each jaw. They attach to skin sucking in blood and injecting anticoagulants in the host body that lessens the pain from penetrating. The teeth are sharp enough to pierce through any skin (of mammals), no matter how thick it is. 

Baby leeches stay the same throughout their lifecycle without changing a bit and just growing in size. Their body is solid, strong, and flexible because of the circular, transverse, and longitudinal muscles that make up their bodies. Leeches have five pairs of simple eyes that light, motion, and surface.
