Developmental stages of Alebion lobatus Cressey, 1970 (Copepoda: Euryphoridae) found parasitic on the sandbar shark ( Carcharhinus plumbeus (Nardo, 1827)) in the western North Atlantic, and a phylogenetic analysis of the genus Alebion Krøyer , 1863
Three stages of copepodids, two preadults, and male and female adult Alebion lobatus collected from sandbar sharks (Carcharhinus plumbeus) in the western North Atlantic are described. Copepodids were found on the external body surface of hosts in hollows which were apparently formed by the absence o...
