This report describes the first record of the piscicolid leech Pontobdella macrothela from Mozambique waters and the first record of P. macrothela parasitizing a Grey Reef Shark (Carcharhinus amblyrhynchos). The leech, P. macrothela, was found attached externally between the third and fourth gill slits of a shark captured off Vamizi Island, Quirimbas Archipelago, northern Mozambique.

Interspecific Comparisons

Upeneus stenopsis n. sp. is described based on four specimens collected off northern Australia and Quezon Island,Philippines, at depths between 165 to 275 m and compared with four closely related species: the deep-water dwellingUpeneus davidaromi (Red Sea) and U. mascareinsis (Western Indian Ocean) and the shallow Indo-West Pacific species,U. subvittatus and U. vittatus. The new species can be distinguished from all other Upeneus species by a narrow caudalpeduncle and a combination of morphometric and meristic characters. This is the first record of a deep-water goatfish ofthe genus Upeneus from the Pacific. A juvenile Upeneus collected off Quezon at 127–142 m depth was also assigned tothe new species and compared to four similar-sized (69–79 mm SL) specimens of U. mascareinsis. A diagnosis is providedfor U. subvittatus, along with evidence of its occurrence in the Eastern Indian Ocean and interspecific comparisons. Thecontinued need to screen scientific fish collections for the occurrence of undescribed species that have successfully colonized and adapted to the depth zone surrounding the ocean margin is outlined.

Morphological Differences

An immature female specimen of rough shark was collected south of Reunion Island in the Madagascar Basin in 2009 aboard R/V Dr. Fridtjof Nansen, representing the first official record of the family Oxynotidae in the western Indian Ocean.  The specimen is herein identified as Oxynotus sp. due to morphological differences with its closely similar congeners O. centrina and O. bruniensis regarding morphometrics, shape of dorsal, pectoral and caudal fins, shape of the head and colouration, refuting the hypothesis of occurrence of these two species in the region.  These results indicate that Oxynotus sp. is possibly an undescribed species.  A general description of the external morphology, external morphometrics and photographs of Oxynotus sp. are provided.  The specimen has a hepatosomatic index of 36.33% which reveals that it was possibly approaching maturation, suggesting that a viable population of Oxynotus sp. exists in the western Indian Ocean.  Intraspecific variations in O. centrina from the Mediterranean Sea and eastern Atlantic Ocean are also noticed, requiring further taxonomic scrutiny.
