“…brevicaudata have ever been published, although information on leeches that parasitize the stingray can be found in blog posts. The genus Branchellion Savigny, 1822 consists of eight species of marine leeches that parasitize chondrichthyans, mainly batoids (Ruiz-Escobar and Oceguera-Figueroa, 2019). In a few cases, members parasitizing teleosts were reported (Savigny, 1822;van Beneden and Hesse, 1864;Blanchard, 1894).…”

A New Species of Branchellion (Hirudinea: Piscicolidae) Parasitizing the Gills of Short-Tail Stingrays (Batoidea: Dasyatidae) from the West Pacific

A new fish leech, Branchellion brevicaudatae sp. n., is described based on specimens parasitizing the gills of the short-tail stingray, Bathytoshia brevicaudata (Hutton, 1875), collected from Japanese waters. The new species can be distinguished from other congeners by having: i) pulsating vesicles emerging from posterior base of branchiae, one pair per somite; ii) dorsal white spots, not arranged in longitudinal row; and iii) blackish body. A phylogenetic tree based on partial sequences of the mitochondrial cytochrome c oxidase subunit I gene from the new species and other piscicolid worms showed that the new species is sister to Branchellion torpedinis Savigny, 1822. This is the first record of Branchellion Savigny, 1822 from Japanese waters.

During captivity, round stingrays, Urobatis halleri, became infected with the marine leech Branchellion lobata. When adult leeches were deprived of blood meal, they experienced a rapid decrease in body mass and did not survive beyond 25 days. If kept in aquaria with host rays, B. lobata fed frequently and soon produced cocoons, which were discovered adhered to sand grains. A single leech emerged from each cocoon (at ~ 21 days), and was either preserved for histology or molecular analysis, or monitored for development by introduction to new hosts in aquaria. Over a 74-day observation period, leeches grew from ~ 2 to 8 mm without becoming mature. Newly hatched leeches differed from adults in lacking branchiae and apparent pulsatile vesicles. The microbiome of the hatchlings was dominated by a specific, but undescribed, member of the gammaproteobacteria, also recovered previously from the adult leech microbiome. Raising B. lobata in captivity provided an opportunity to examine their reproductive strategy and early developmental process, adding to our limited knowledge of this common group of parasites.
