Storage and recovery of elastic potential energy powers ballistic prey capture in toads
SUMMARY Ballistic tongue projection in toads is a remarkably fast and powerful movement. The goals of this study were to: (1) quantify in vivo power output and activity of the depressor mandibulaeExpand

CHAPTER 5 – Feeding in Frogs
Comparative studies have demonstrated that frogs exhibit at least three different mechanisms to protract their tongues. These are mechanical pulling, inertial elongation, and hydrostatic elongation.Expand

Do arm postures vary with the speed of reaching?
Do arm postures vary with the speed of reaching? For reaching movements in one plane, the hand has been observed to follow a similar path regardless of speed. Recent work on the control of moreExpand

Evolution of forelimb movement patterns for prey manipulation in anurans.
Unlike other amphibians, frogs often use their forelimbs to capture and transport prey. In the present study, high-speed videography was used to observe forelimb use during feeding in a diverse groupExpand

Is titin a ‘winding filament’? A new twist on muscle contraction
Recent studies have demonstrated a role for the elastic protein titin in active muscle, but the mechanisms by which titin plays this role remain to be elucidated. In active muscle, Ca2+-binding hasExpand

Paedomorphosis and simplification in the nervous system of salamanders.
Comparative neuroanatomists since Herrick [1914] have been aware of the paradox that the brain of amphibians, especially salamanders, is less complex than one would expect based on their phylogeneticExpand

A prey-type dependent hypoglossal feedback system in the frog Rana pipiens.
Nerve transection experiments combined with high-speed videography and electromyography were used to characterize a prey-type dependent hypoglossal feedback system which coordinates mouth opening andExpand

Morphology and histochemistry of the hyolingual apparatus in chameleons
We reexamined the morphological and functional properties of the hyoid, the tongue pad, and hyolingual musculature in chameleons. Dissections and histological sections indicated the presence of fiveExpand

Functional implications of supercontracting muscle in the chameleon tongue retractors.
Chameleons capture prey items using a ballistic tongue projection mechanism that is unique among lizards. During prey capture, the tongue can be projected up to two full body lengths and may extendExpand

Interspecific aggressive behaviour in salamanders: species-specific interference or misidentification?
Abstract This research analyses variation in the interspecific aggressive behaviour of two salamander species, Plethodon jordani and P. glutinosus, from three localities which differ in extent ofExpand
