We report the presence of an aglomerular kidney in the pelagic deep-sea fish Saccopharynxampullaceus (Saccopharyngiformes: Saccopharyngidae). The thin kidney is unpaired and ribbon-like rostrally, while it is thicker caudally with a rod-like shape. Light microscopic observation of serial sections revealed no glomeruli at all. The kidney is composed of renal tubules, sinusoids and capillaries of the renal portal system and extensive interstitial lymphoid tissues. Each renal tubule is surrounded…

Histologic evaluation of the renal system in the lined seahorse Hippocampus erectus reveals a cranial kidney with low to moderate cellularity, composed of a central dorsal aorta, endothelial lined


The Aglomerular Kidney of the Deep-sea Fish, Ateleopus japonicus (Ateleopodiformes: Ateleopodidae): Evidence of Wider Occurrence of the Aglomerular Condition in Teleostei
The presence of an aglomerular kidney in the benthopelagic deep-sea fish Ateleopus japonicus (Ateleopodidae: Jellynose fish), which consists of a pair of strap-like bands located in the typical retroperitoneal position, is reported.
Cranial morphology of Ateleopus japonicus (Ateleopodidae: Ateleopodiformes), with a discussion on metamorphic mouth migration and lampridiform affinities
The cranial osteology and myology in the ateleopodiform Ateleopus japonicus were studied and the deep insertion of the rostral cartilage into an open space in the ethmoid region is suggested as a synapomorphy of the order and Lampridiformes.
Adaptations in mesopelagic fishes
Mesopelagic fishes were collected from depths of 400 to 900 m off Oregon (USA) in September 1983, October 1985 and June 1989. Species of mesopelagic fish without diel vertical migrations

The upper reaches of the deep ocean contain many bathypelagic fishes with a capacious, gas-filled swimbladder. But living within and below this region are also numerous species in which this

Structure and functional development of the eel leptocephalus Ariosoma balearicum (De La Roche, 1809)
The leptocephalus of the bandtooth conger Ariosoma balearicum demonstrates many features of structural and functional immaturity and, until transformed by metamorphosis, appears to be an obligatory inhabitant of the open ocean.
