Batoid wing skeletal structure: Novel morphologies, mechanical implications, and phylogenetic patterns
High‐resolution radiography reveals the pattern of calcification in batoid wing elements, and their organization within the fin ray, to be considerably more complex and phylogenetically variable than previously thought.
Material properties and biochemical composition of mineralized vertebral cartilage in seven elasmobranch species (Chondrichthyes)
Ver vertebral cartilage was found to be as stiff and strong as mammalian trabecular bone and a significant predictor of material properties.
Kinematics of aquatic and terrestrial prey capture in Terrapene carolina, with implications for the evolution of feeding in cryptodire turtles.
It is concluded that the function of hyoid depression during aquatic feeding in cryptodire turtles is to prevent the forward motion of the predator from pushing the prey away (compensatory suction), and it is not appropriate to use extant turtles in attempts to reconstruct the terrestrial feeding mechanisms of primitive amniotes.
Kinematic Analysis of Suction Feeding in the Nurse Shark, Ginglymostoma cirratum (Orectolobiformes, Ginglymostomatidae)
The feeding kinematics of a suction feeding shark, the nurse shark Ginglymostoma cirratum, are investigated to test for differences in the timing and magnitude of feeding components with other shark taxa when sharks were fed pieces of bony fish.
Maneuvering in juvenile carcharhinid and sphyrnid sharks: the role of the hammerhead shark cephalofoil.
It is shown that hammerhead sharks demonstrate greater lateral flexure in a turn than carcharhinids, and that this flexibility may be due to cross sectional shape rather than number of vertebrae.
Olfactory morphology of carcharhinid and sphyrnid sharks: Does the cephalofoil confer a sensory advantage?
Many hypotheses have been advanced to explain the adaptive significance of the sphyrnid cephalofoil, including potential advantages of spacing the olfactory organs at the distal tips of the broad
Mineralized cartilage in the skeleton of chondrichthyan fishes.
This work presents levels of organization in which crystal orientation/size delimits three calcification types (areolar, globular, and prismatic) that interact in two distinct skeletal types, vertebral and tessellated cartilage.
Linkage mechanics and power amplification of the mantis shrimp's strike
The results of the morphological, kinematic and mechanical analyses suggest a multi-faceted mechanical system that integrates latches, linkages and lever arms and is powered by multiple sites of cuticular energy storage.
The evolution of cranial design, diet, and feeding mechanisms in batoid fishes.
The data imply that food habits exhibit strong independent and convergent evolution and that suites of morphologies are associated with certain diets; however, lack of behavioral data for this clade, and one example of divergent diets underlain by convergent morphology, caution against the assumption of simplistic relationships between form and function.
