Snout allometry in seahorses: insights on optimisation of pivot feeding performance during ontogeny.
As juvenile life-history stages are subjected to strong selection, these stages often show levels of performance approaching those of adults, or show a disproportionately rapid increase of performance with age. Although testing performance capacity in aquatic suction feeders is often problematic, in pivot feeders such as seahorses models have been proposed to estimate whether snout length is op...
متن کاملEffects of snout dimensions on the hydrodynamics of suction feeding in juvenile and adult seahorses.
Seahorses give birth to juveniles having a fully functional feeding apparatus, and juvenile feeding behaviour shows striking similarities to that of adults. However, a significant allometric growth of the snout is observed during which the snout shape changes from relatively short and broad in juveniles to relatively long and slender in adults. Since the shape of the buccal cavity is a critical...
متن کاملNew Insights into Muscle Function during Pivot Feeding in Seahorses
Seahorses, pipefish and their syngnathiform relatives are considered unique amongst fishes in using elastic recoil of post-cranial tendons to pivot the head extremely quickly towards small crustacean prey. It is known that pipefish activate the epaxial muscles for a considerable time before striking, at which rotations of the head and the hyoid are temporarily prevented to allow energy storage ...
متن کاملThe effect of food type on phenotypic plasticity of sword tail, Xiphophurus helleri, during early ontogeny
Phenotypic plasticity is an important mechanism of phenotypic adaptation in response to environmental conditions. This study was conducted to investigate the effect of food type on the body shape of swordtail, Xiphoohurus helleri, during early development using geometric morphometric method. For this purpose, two treatments including feed by Artemia naupli and commercial Biomar diet were used i...
متن کاملThe ontogeny of bite-force performance in American alligator (Alligator mississippiensis)
American alligators Alligator mississippiensis undergo major transformations in morphology and ecology during development. These include several thousand-fold changes in body mass, modified snout and dental proportions, and shifts in diet from small, delicate foodstuffs to the inclusion of increasingly larger, more robust prey. How these changes in anatomical form contribute to actual physical ...
