“…George Cuvier (Cuvier, ) may have been the first to observe that the cardiac ventricle is divided into left and right ventricles by a full septum not only in mammals and birds, but also in crocodilians. Nowadays, molecular biology is making an ever stronger case that the hearts of the amniotic vertebrates, specifically mammals, birds and reptiles, share a common building plan during their development whereby evolutionarily conserved transcription factors orchestrate the formation of chambers, junctions, and septal structures (Olson, ; Koshiba‐Takeuchi, ; Jensen et al.…”

Differences between hearts of crocodilians and those of mammals and birds are only partly understood because there is no standardised approach and terminology for describing cardiac structure. Whereas most reptiles have an undivided ventricle, crocodilians have a fully septated ventricle. Their hearts, therefore, are more readily comparable with the hearts of mammals and birds. Here, we describe the heart of a crocodile (Crocodylus noliticus). We use the versatile sequential segmental approach to analysis, juxtaposing several key views of the crocodilian heart to the comparable views of human hearts. In crocodiles, the atrial and ventricular septums are complete but, unlike in placental mammals, the atrial septum is without an oval fossa. The myocardial component of the crocodilian ventricular septum dominates, but the membranous septum likely makes up a greater proportion than in any mammal. In the crocodile, the aortic trunk takes its origin from the left ventricle and is not wedged between the atrioventricular junctions. Consequently, there is a common atrioventricular junction, albeit with separate right and left atrioventricular valvar orifices. As in mammals, nonetheless, the crocodilian left atrioventricular valvar orifice is cranial to the right atrioventricular valvar orifice. By applying a method of analysis and terminology usually restricted to the human heart, we build from the considerable existing literature to show neglected and overlooked shared features, such as the offset between the left and right atrioventricular valvar orifices. Such commonalities are surprising given the substantial evolutionary divergence of the archosaur and synapsid lineages, and likely reflect evolutionarily shared morphogenetic programmes.

Since 1966, when the last major work on fossil scombroid fishes (Scombroidei, Perciformes) from England appeared, our knowledge of the taxonomy and systematics of Recent scombroids has been thoroughly updated, improved and studied in the context of cladistic methods. In comparison, our knowledge of the fossil taxa has lagged much behind. As part of a revision of all fossil and Recent scombroid fishes, the present paper describes an updated systematic palaeontology of the English fossil taxa. These are a subset of taxa subject to a cladistic analysis of Recent and fossil genera combined, the results of which will appear in future papers. Three new genera are erected, two species transferred to other, already existing, ones and a new species is described (in a new genus). The author follows the opinion that Eothynnus Woodward, 1901 is a carangid. Several individual specimens are re-identified. The systematic affinities of Tamesichthys Casier, 1966, Eocoelopoma Woodward, 1901, Scombramphodon Woodward, 1901, Sphyraenodus Agassiz, 1844, Wetherellus Casier, 1966 and Woodwardella Casier, 1966, and a few new taxa, are here considered unknown. Aglyptorhynchus Casier, 1966 is probably a billfish, and Cylindracanthus Leidy, 1856, is possibly one as well, even though there are serious objections to this.

“…This study describes the gross morphology and ultrastructure of the filter pads in 9 of the 11 species of mobulids: Manta birostris (Walbaum, ), Mobula eregoodootenkee (Cuvier, ) , Mobula hypostoma (Bancroft, ) , Mobula japanica (Müller and Henle, ) , Mobula kuhlii (Valenciennes in Müller and Henle, ) , Mobula mobular (Bonnaterre, ) , Mobula munkiana (Notarbartolo‐di‐Sciara, ) , Mobula tarapacana (Philippi, ), and Mobula thurstoni (Lloyd, ). The aims are four‐fold: 1) to provide a clear description of the filter anatomy for each species, 2) to describe the microscopic surface anatomy of the filter using scanning electron microscopy (SEM), 3) to describe the orientation of the branchial arch in situ so that we may assess fluid flow regimes as they move throughout the oropharyngeal cavity, and 4) to combine the anatomical information and fluid flow speeds estimated from field‐collected swimming speeds to infer the mechanism of particle entrapment.…”

The filter pads and filtration mechanisms of the devil rays: Variation at macro and microscopic scales

Three lineages of cartilaginous fishes have independently evolved filter feeding (Lamniformes: Megachasma and Cetorhinus, Orectolobiformes: Rhincodon, and Mobulidae: Manta and Mobula); and the structure of the branchial filters is different in each group. The filter in Rhincodon typus has been described; species within the Lamniformes have simple filamentous filters, but the anatomy and ultrastructure of the branchial filter in the mobulid rays varies and is of functional interest. In most fishes, branchial gill rakers are elongated structures located along the anterior ceratobranchial and/or epibranchial arches; however, mobulid gill rakers are highly modified, flattened, lobe-like structures located on the anterior and posterior epibranchial elements as well as the ceratobranchials. The ultrastructure of the filter lobes can be smooth or covered by a layer of microcilia, and some are denticulated along the dorsal and ventral lobe surface. Flow through the mobulid oropharyngeal cavity differs from other filter-feeding fishes in that water must rapidly deviate from the free stream direction. There is an abrupt 90° turn from the initial inflowing path to move through the laterally directed branchial filter pores, over the gill tissue, and out the ventrally located gill slits. The deviation in the flow must result in tangential shearing stress across the filter surface. This implies that mobulids can use cross-flow filtration in which this shearing force serves as a mechanism to resuspend food particles initially caught by sieving or another capture mode. These particles will be transported by the cross filter flow toward the esophagus. We propose that species with cilia on the rakers augment the shear mediated movement of particles along the filter with ciliary transport.
