Kinematic Analysis of Suction Feeding in the Nurse Shark, Ginglymostoma cirratum (Orectolobiformes, Ginglymostomatidae)
Abstract Inertial suction feeding is known to occur in some sharks, but the sequence and temporal kinematics of head and jaw movements have not been defined. We investigated the feeding kinematics of… Expand

Response of the hammerhead shark olfactory epithelium to amino acid stimuli
Sharks and rays are highly sensitive to chemical stimuli in their natural environment but several hypotheses predict that hammerhead sharks, with their expanded head and enlarged olfactory… Expand

Modelling tooth–prey interactions in sharks: the importance of dynamic testing
The shape of shark teeth varies among species, but traditional testing protocols have revealed no predictive relationship between shark tooth morphology and performance. We developed a dynamic… Expand

Comparison of chela size and pincer force in scorpions; getting a first grip
A key feature of the ancient body plan of scorpions is the pincer or chela. These multifunctional structures vary considerably in size and shape between different scorpion species. Here we provide… Expand

Performance of teeth of lingcod, Ophiodon elongatus, over ontogeny.
Fish teeth can play several roles during feeding; capture, retention, and processing. In many fish lineages teeth may be present on non-jaw cranial bones that lack opposing teeth, such as the vomer… Expand

Always chew your food: freshwater stingrays use mastication to process tough insect prey
Chewing, characterized by shearing jaw motions and high-crowned molar teeth, is considered an evolutionary innovation that spurred dietary diversification and evolutionary radiation of mammals.… Expand

The retro-articular process, streptostyly and the caecilian jaw closing system.
Caecilians have two functionally separate sets of jaw closing muscles. The jaw adductor muscles are parallel fibered muscles positioned close to the jaw joint and their lever mechanics suggests they… Expand

Gumfooted lines in black widow cobwebs and the mechanical properties of spider capture silk.
Orb-weaving spiders produce webs using two types of silk that have radically different mechanical properties. The dragline silk used to construct the supporting frame and radii of the web is stiff… Expand

Comparison of the Structure and Composition of the Branchial Filters in Suspension Feeding Elasmobranchs
The four, evolutionarily independent, lineages of suspension feeding elasmobranchs have two types of branchial filters. The first is a robust, flattened filter pad akin to a colander (e.g., whale… Expand
