“…Watson et al (1984) included champsodontids and chiasmodontids in the Trachinoidei, but concluded that the suborder was probably polyphyletic and did not comment specifically on champsodontid relationships. Pietsch (1989) provided the first cladistic analysis of the Trachinoidei while attempting to establish outgroup relationships for a study of the Uranoscopidae. Ten families were included in his phylogeny, which proposed a sister group relationship of Champsodontidae and Chiasmodontidae embedded within the middle of the group.…”

“…A critical re-evaluation of Pietsch and Zabetian's evidence by Johnson (1993) suggested that the Trachinoidei sensu Pietsch and Zabetian was not adequately diagnose& and noted that several, often informative, character complexes had not been considered. Given that these complexes exhibit morphological variation among the trachinoids, their inclusion would have considerably altered the conclusions of Pietsch (1989) and Pietsch and Zabetian (1990). Johnson (1993: 14) specifically questioned the champsodontid/chiasmodontid relationship, citing a number of trenchant differences in morphology of the dorsal-fin pterygiophores and gill arches.…”

“…1), but opinions vary among authors and little, if any, evidence has been provided to support these opinions. Pietsch (1989) and Pietsch and Zabetian (1990) provided a cladistic definition of a Trachinoidei that included the Champsodontidae and Chiasmodontidae as sister taxa. Reservations concerning their evidence and conclusions were voiced by Johnson (1993) and Mooi and Gill (1995), who suggested alternative relationships including placement among the Scorpaenoidei (sensu Mooi and Gill, 1995).…”

. 1997. Dismantling the Trachinoidei: evidence of a scorpaenoid relationship for the Champsodontidae. Ichthyol. Res., 44 (2): 143-176. AbstractAn examination of the osteology and myology of the Champsodontidae reveals a number of apomorphic features (e.g., double-headed palatine, large pelvic radial, epaxial muscle inserting on the medial pelvic-fin ray, posterior levator internus inserting on the third epibranchial). The evidence for a Champsodontidae/Chiasmodontidae relationship is examined through a re-evaluation of the basal characters used to define the suborder Trachinoidei. The Champsodoutidae are removed from the Trachinoidei and a chiasmodontid sister relationship is rejected. After investigation of severaI possible alternative relationships (Paracanthopterygii, Gobioidei, Callionymoidei, Kurtoidei, Apogonidae, Blennioidei, Trichodontidae), champsodontids are hypothesized to be members of the perciform suborder Scorpaenoidei. This hypothesis is based largely on the synapomorphy of a parietal spine with an opening for passage of the supratemporal sensory canal, a unique condition of champsodontids and some scorpaenoids. A shared Type 1 epaxial muscle morphology, with separate fibre insertions on the distal tips of the spine-bearing dorsal-fin pterygiophores, is unusual and probably derived among perciforms. Champsodontids also share with some scorpaenoids Type 5 spinoid scales and the origin of Baudelot's ligament from the first vertebra rather than the basi-occipital, although neither of these features is unique to these taxa. The occurrence of an enclosed sensory. canal on the parietals of Trichodontidae suggest that their relationships might also lie with the Scorpaenoidei. Arguments pertaining to the removal of champsodontids from the trachinoids apply equally to the hypothesized membership of the Cheimarrichthyidae, Pinguipedidae, Percophididae, Trichonotidae, Creediidae, Chiasmodontidae, and notothenioids in the Trachinoidei. Inclusion of these taxa within the Trachinoidei is not well-supported, and their relationships require further investigation.

The Gallbladder ofUranoscopus ScaberL. (Teleost Perciform Fish) is Lined by Specialized Cholecystocytes

The gallbladder of Uranoscopus exhibits a mucosal surface layer of simple columnar epithelium composed of specialized cholecystocytes. The apices show storage and mucous secretions, typical microvilli, and very apical projections extending deep into the luminal contents. Many organelles and heterogeneous vesicles of diverse size fill the cytoplasm, including neutral mucins, mitochondria, peroxisomes, lysosomal bodies, and lipid-rich deposits with cholesterol inclusions. The fibromuscular layer shows little blood supply and contains scattered lymph-like walls with minute cholesterol inclusions. The remaining muscular, subserosal, and serosal or adventitial layers of this species do not show any histologic differences to those of other Vertebrates. It was unexpected to find cholesterol inclusions in the fatty deposits of the cholecystocytes, similar to those noted in human cholesterolosis and in some forms of hypercholesterolemia, in this teleostean. In addition, aggregations of mitochondria and anomalous mitochondrial morphologies were found that resemble oncocytoma-like changes. Anat Rec, 294:1890Rec, 294: -1903Rec, 294: , 2011.

A new genus and species of percomorph fish, Pietschellus aenigmaticus gen. et sp. nov., is described from the Eocene (Ypresian) micritic limestone of the Monte Postale site of the Monte Bolca locality, northern Italy. This new percomorph taxon is based on a single well-preserved nearly complete specimen that exhibits a unique combination of features. A detailed comparative analysis indicates that Pietschellus possibly was a benthic fish which shares several character states with certain lophiiform, callionymoid, trachinoid, blennioid, pterygocephalid, cottoid and scorpaenoid taxa. Most of these shared character states, however, are reductive and seem to be related to the convergent benthic lifestyle and/or to the relative elongation of the body, being the product of parallel or convergent evolution. Therefore, the present evidence does not favour any sister-group relationship and, as a consequence, Pietschellus is placed as incertae sedis within the percomorph fishes.
