| الوصف: | Abstract 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. |
