Except for Antarctica, [4] leeches are found throughout the world but are at their most abundant in temperate lakes and ponds in the northern hemisphere. The majority of freshwater leeches are found in the shallow, vegetated areas on the edges of ponds, lakes and slow-moving streams; very few species tolerate fast-flowing water.
Medicinal leeches have been found to secrete saliva containing about 60 different proteins. [8] These achieve a wide variety of goals useful to the leech as it feeds, helping to keep the blood in liquid form and increasing blood flow in the affected area.
"Jawed leeches" - termed "Gnathobdellae" or "Gnathobdellida" - are exclusively found among the Hirudiniformes, but the order contains a number of jawless families as well. .

Aquatic leeches have been found on sites such as the nose, mouth, pharynx, larynx, conjunctiva, trachea, bronchi, esophagus, vagina, bladder, rectum, and the creases of the eyes, [4] Although most instances were found in the nasopharynx, lower airways, or upper esophagus. Humans become victims from bathing or drinking unfiltered water in less ...
They are adapted by developing leaves that repel water, and are called laurophyll or lauroid leaves. Flowers grow on a terminal inflorescence with many panicles on the current season's growth. The panicles grow in clusters of ten or more, reaching 10 to 40 cm (3.9 to 15.7 in) or longer, holding hundreds of small white, yellow, or green flowers ...
