Both are hermaphrodites and possess a Clitellum. Leeches are different from oligochaetes by having suckers on both ends as well as rings that don’t match their internal division. The majority of sponges reside in freshwater habitats.

However, certain species are found in marine and terrestrial habitats. The most well-known species like the medicinal leech Hirudo medicinalis is hematophagous. They attach their bodies to the host using suckers and consuming blood, after first releasing the peptide called hirudin, which prevents blood from getting clots. Jaws that pierce the skin can be replaced by different species by a beak that is pushed through the skin.

They are ranked seventh in the overall diversity of species among all species. 

Anatomically, they distinguish themselves from the other arthropods because the body’s typical segments are bonded into two tagmata: the prosoma or cephalothorax, and the opisthosoma, also known as the abdomen, joined by a tiny cylindrical pedicel. However, since there is no evidence from paleontology or embryology that spiders were a separate thorax-like segment There is an argument against the term”cephalothorax”, which is a reference to a fused cephalon as well as the thorax.
