EMBRYONIC SURFACE CILIATED CELLS IN ELEUTHERODACTYLUS URICHI (ANURA: LEPTODACTYLIDAE) %K Eleutherodactylus %K direct development %K embryonic ciliation %R 10.22099/ijsts.2006.2742 %X While our knowledge of anuran embryonic and larval surface ciliation and their diversity ofciliation patterns are significant, very few references were noticed on embryonic ciliation in direct-developinganurans, such as species in the genus Eleutherodactylus. Eleutherodactylus urichi embryos were found tohave surface ciliated cells during much of their development until a few days before hatching. Ciliation wasmost prominent on the pharyngeal region and on the tail fins, both regions believed to have a respiratory role,and supporting the hypothesis that embryonic ciliation in amphibians serves principally to aid respiration bymoving intracapsular fluid. The limb-buds were also well ciliated, an evolutionary novelty since in mostanurans with a tadpole stage, surface ciliation regresses before limbs show significant development. %U https://ijsts.shirazu.ac.ir/article_2742_b48996133ac6f8ea6f2f669543e84098.pdf
