Extraocular muscles are classically grouped as four rectus and two oblique muscles. However, their description and potential associations with species behavior are limited. The objective was to characterize extraocular muscles in four Myliobatoidei rays from diverse habitats with divergent behaviors. Heads (10 per species) of Dasyatis hypostigma, Gymnura altavela, Mobula thurstoni and Pteroplatytrygon violacea were decalcified and dissected to characterize and describe extraocular muscles… Expand
The fine structure of the turbot eye (Scophtalmus maximus): A macro‐anatomical, light and scanning electron microscopical study
This study is the first to present detailed descriptions of morphological structures and morphometric data for all the layers of the turbot eye using gross, light and scanning electron microscope examinations. Expand
Reef manta ray cephalic lobe movements are modulated during social interactions
A standardized method to assess manta ray behavior in the wild via focal sampling and frame-by-frame video analysis finds that cephalic lobe curls were modulated when approaching both conspecifics and human divers, as well as during interactions with cleaner fish, suggesting that these lobes may be used in sensing water movements, olfactory sensing, and/or gestural communication.

Morphological description of ovary and uterus of the nurse shark (Ginglymostoma cirratum) caught off at the Fortaleza coast, Northeast Brazil
The nurse shark, Ginglymostoma cirratum (Bonnaterre, 1778) is one of the most studied species of elasmobranchs. However, the knowledge of their reproductive biology is still relatively rare, particExpand

Comparative anatomy of the orbita throughout various vertebrates revealed that the extrinsic ocular muscles vary in shape and number, and it was suggested that the original form of the 3 straight and one oblique muscles serve to conduct their components into various types of differentiation and degeneration.

Morphology and phylogenetic significance of the pectoral articular region in elasmobranchs (Chondrichthyes)
The variation and distribution of the new characters discussed provide new insights for the evolution of the pectoral endoskeleton in chondrichthyans, and reinforce the necessity of in-depth anatomical reviews of certain characters employed in previous higher-level phylogenetic studies of elasmobranchs.

Variations and anomalies of the human orbital muscles
Some rare and hitherto unreported uni- and bilateral anomalies of the orbital rectus muscles (duplications, triplication, accessory bellies, interrectal muscular bridges, false insertion) are described, found by chance during the dissections of three cadavers. Expand
Estudo anatômico comparativo da região cefálica pré-branquial de Sphyrna lewini (Griffith & Smith) e Rhizoprionodon lalandii (Valenciennes) (Elasmobranchii, Carcharhiniformes) relacionados com a presença do cefalofólio em Sphyrna Rafinesque
It was observed that the oculomolorius branch "a" does not inervate the adductor mandibulae as it was mentioned in a previous paper and the myological structures and the inervation pattern presented diagnostic characters. Expand
Organization of the six motor nuclei innervating the ocular muscles in lamprey
The topography of motoneurons supplying each of the six ocular muscles of the lamprey, Lampetra fluviatilis, was studied by selective application of HRP to the cut nerves of identified muscles. InExpand
Evolutionary history of the devilrays (Chondrichthyes: Myliobatiformes) from fossil and morphological inference
The first detailed comparative description of teeth belonging to most of the living and fossil mobulids is performed, providing clues to the evolutionary history of this clade since the Early Eocene, including the gradual lack in tooth interlocking toward the filter-feeding strategy, whereas the preservation of cusped teeth without feeding function in modern filter-feeder mobulid is interpreted as a tool for precopulatory purposes.

Innervation and structure of extraocular muscles in the monkey in comparison to those of the cat
The ventral subgroup of abducens motoneurones, which innervate both the lateral Rectus and accessory lateral rectus muscles, thus do not occupy a brain stem location similar to the cat accessory abducen nucleus, whose motoneURones innervates the retractor bulbi muscle. Expand
Visual fields of four batoid fishes: a comparative study
This study represents the first comparative assessment of visual fields in basal vertebrates and found the most phylogenetically basal species, the clearnose skate (Raja eglanteria), had the most reduced visual field in contrast to the more derived ray species. Expand
Horizontal rectus muscle anatomy in naturally and artificially strabismic monkeys.
Major structural abnormalities of horizontal rectus EOMs and associated pulleys are unrelated to natural or artificial horizontal strabismus in the monkeys studied, and the accessory lateral rectus (ALR) EOM was present in all specimens, but was small, inconsistently located, and sparsely innervated.

Body plan convergence in the evolution of skates and rays (Chondrichthyes: Batoidea).
A resolved, robust and time-calibrated batoid phylogeny is constructed using mitochondrial genomes, nuclear genes, and fossils, sampling densely across taxa and finding body plan convergence appears to be widespread in batoids. Expand
