Ghory http://www.iaees.org/publications/journals/arthropods/articles/2023-12(4)/description-of-larval-stages-of-Alpheus-lobidens.pdf> The Alpheus lobidens is a widely distributed snapping shrimp that lives on soft and hard bottoms in warm coastal environments (Hamdy and Dorgham, 2018). The berried female of Alpheus lobidens De Haan, 1850 was collected from Buleji (Karachi, Pakistan) and kept in the laboratory. The larvae hatched after 2 days and existed within 7 days at room temperature 23oC - 28oC in filtered seawater with a salinity of 37 - 40 parts per thousand and a pH of 7.5 - 7.8. Artemia nauplii were used to feed the larvae. Two zoeal stages are described, illustrated and compared with those of its congener's larvae known previously.
