Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola
The Anatomical Record, EarlyView.Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

Snake graph calculus and cluster algebras from surfaces II: Self-crossing snake graphs [PDF]
arXiv, 2014 Snake graphs appear naturally in the theory of cluster algebras. For cluster algebras from surfaces, each cluster variable is given by a formula which is parametrized by the perfect matchings of a snake graph. In this paper, we continue our study of snake graphs from a combinatorial point of view.

Circadian rhythm of locomotor activity in Bothrops jararacussu (Serpentes: Viperidae) [PDF]
Biotemas, 2007 Many biochemical, physiological, and behavioral parameters exhibited by organisms show daily fluctuations, and most of these fluctuations persist when the organisms are maintained in constant environmental conditions, thus demonstrating that they are ...

Subdivision based snakes for contour detection [PDF]
arXiv, 2018 In this paper we propose a method for computing the contour of an object in an image using a snake represented as a subdivision curve. The evolution of the snake is driven by its control points which are computed minimizing an energy that pushes the snake towards the boundary of the interest region.
