The musculature and skeleton of the pelvic fin of the crocodile shark, Pseudocarcharias kamoharai (Matsubara, 1936) (Elasmobranchii: Lamniformes): Morphology and sexual dimorphism

The Anatomical Record, EarlyView.
This work brings new information on the sexual characteristics of the crocodile shark (Pseudocarcharias kamoharai) exploring the pelvic fin musculature, as well as the siphon sac and the musculature and skeleton of the clasper. Our paper is the first to point out clearly the sexual dimorphism related exclusively to the pelvic fin musculature in males ...

Early evolution of the gular musculature and its innervation in ray‐finned fishes

The Anatomical Record, EarlyView.
Abstract Gular muscles are an important but often overlooked component of cranial anatomy in bony fishes. They are located on the ventral surface of the head and are derived from the mandibular and hyoid arches. We present a comprehensive review of the gular musculature and its innervation across early diverging actinopterygian lineages. By integrating

Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

The Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

The Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.
