[34] [36] The glossiphoniids brood their eggs, either by attaching the cocoon to the substrate and covering it with their ventral surface, or by securing the cocoon to their ventral surface, and even carrying the newly hatched young to their first meal. [37] When breeding, most marine leeches leave their hosts and become free-living in estuaries.
Leeches are hermaphrodites, and mating may take place on or off the fish host, but in either case, the cocoon, usually containing a single egg, is deposited elsewhere, usually stuck to a stone or piece of vegetation, or even to the carapace of a crustacean. When the egg hatches, the juvenile leech has about a week to find a suitable fish host ...
Glossiphoniid leeches exhibit remarkable parental care, the most highly developed one among the known annelids. They produce a membranous bag to hold the eggs, which is carried on the underside. The young attach to the parent's belly after hatching and are thus ferried to their first meal. [6] Certain Glossiphoniidae parasitize amphibian species.

Large adults can consume up to ten times their body weight in a single meal, with 5–15 mL being the average volume taken. [5] These leeches can live for up to a year between feedings. [6] Medicinal leeches are hermaphrodites that reproduce by sexual mating, laying eggs in clutches of up to 50 near (but not under) water, and in shaded, humid ...
Haementeria ghilianii is a species of leech in the Glossiphoniidae family, comprising freshwater proboscis-bearing leeches. Colloquially, they are known as the Amazon giant leech . Following its initial description in 1849, additional details were provided based on specimens from French Guiana in 1899, after which the species was largely ...

There are four bundles of one to twenty-five chaetae on each segment; these have muscles attached to their bases and can be extended or retracted. [2] Leeches, order Hirudinida, [4] mostly have flattened bodies, usually tapered at both ends. They have a fixed number of segments, 33, but the segmentation is not visible externally because the ...
