PhylogeneticS
Kingdom: Animalia
-_-Multicellular, eukaryotic organisms
-_contains a wide-range of organisms which share common properties which go to define animals as a distinct group of life-forms
- Sexual reproduction is a necessity as well, so is mobility
_Phylum: Annelida
- _All members of the group are to some extent segmented, in other words, made up of segments that are formed by subdivisions that partially transect the body cavity.
- Can be found over the world
- Found in marine, freshwater, and terrestrial environments. Ecologically, they range from passive filter feeders to voracious and active predators.
Class: Hirudinea
- Leeches are unlike other annelids in several ways. They have a fixed number of segments (usually 34), a dorso-ventrally flattened body, both an anterior and posterior sucker (usually), no parapodia, and usually no setae.
-Most leeches are found in freshwater habitats, but a few are marine and some are terrestrial (but they require warm, moist conditions).
Order: Acanthobdellida
-An order of parasitic worms that lack an anterior sucker.
-Chaetae occur in the anterior region.
-There is one genus
-Body with 14 to 15 segments; all species parasitic or commensal on freshwater crayfish
Family: Hirudinidae
- family of aquatic leeches that have 5-ringed segments, 5 pairs of eyes
- usually 3-toothed jaws and that include the common medicinal leech
Genus: Macrobdella
- Species under this Macrobdella Decora
