Pontobdella is a species of marine leeches with a cosmopolitan distribution. They are covered with tubercles and their primary hosts are rays, sharks, skates, and sawfish.
Distribution
[edit]Pontobdella species are found on the coasts of Africa, Eurasia, the Americas, New Zealand, and even Antarctica.[1]
Characteristics
[edit]A prominent feature of Pontobdella leeches are the "wart-like" tubercles which cover their bodies all over. Pontobdella's hosts are generally elasmobranchs – rays, sharks, skates, and sawfish. Each segment of the leech's body (and all leeches have 32) has three or four annuli.[2][3]: 236 They are large leeches; one species, Pontobdella novaezealandiae, can grow as long as 20 centimetres.[3]: 236 [4]
Classification
[edit]The genus was described by William Elford Leach. Pontobdella is placed in the family Piscicolidae,[1] and is confirmed to form a monophyletic grouping.[5]: 193
