Gekko gecko as a model organism for understanding aspects of laryngeal vocal evolution

This study investigates alarm calls in Gekko gecko, revealing distinct call types and laryngeal biomechanics, suggesting G. gecko as a model for understanding vertebrate vocal evolution.

The pharynx of the iconic stem-group chondrichthyan Acanthodes (Agassiz, 1833) revisited with micro computed tomography.

This study uses micro CT to analyze the pharyngeal skeleton of Acanthodes confusus, revealing a mix of osteichthyan and chondrichthyan features and providing insights into its feeding mechanism.

Armed to the teeth: the underestimated diversity in tooth shape in snakes and its relationship to feeding constraints

This study examines tooth shape diversity in snakes and identifies factors like prey hardness and feeding behavior that influence tooth morphology.

Measuring the 3D wake of swimming dice snakes using volumetric velocimetry

This study measures the 3D wake of swimming dice snakes using volumetric velocimetry, revealing organized vortex structures and their temporal dynamics.

The mammalian forelimb diversity as a morphological gradient of increasing evolutionary versatility

The paper examines whether the timing of bone condensation in mammalian forelimbs predicts morphological diversity between proximal and distal segments across 600+ species.

Evidence of attack deflection suggests adaptive evolution of wing tails in butterflies

The paper investigates the adaptive evolution of hindwing tails in butterflies by showing they are more frequently attacked and damaged, supporting their role in deflection.

Do substrate roughness and gap distance impact gap-bridging strategies in arboreal chameleons?

This study examines how substrate roughness and gap distance influence tail use in chameleons, finding that tail use increases with distance and roughness enhances crossing ability.

The morphology and evolution of chondrichthyan cranial muscles: a digital dissection of the elephantfish Callorhinchus milii and the catshark Scyliorhinus canicula.

This paper uses digital dissection of elephantfish and catshark skulls to describe their cranial musculoskeletal anatomy and provides new insights into the evolution of chondrichthyan cranial muscles.

Exploring the functional meaning of head shape disparity in aquatic snakes.

The paper examines head shape diversity in aquatic snakes to determine if functional constraints or ecological factors drive morphological variation and whether similar shapes yield similar functional outcomes.

Tooth Shape Adaptations in Aglyphous Colubrid Snakes Inferred from 3D Geometric Morphometrics and Finite Element Analysis

This study uses 3D geometric morphometrics and finite element analysis to compare tooth shape and function in Aglyphous snakes, finding that blunt teeth are adapted for hard prey while sharp teeth are for endothermic prey.

Hydrodynamics of the frontal strike in aquatic snakes: drag, added mass and the possible consequences for prey capture success.

This study examines how head shape affects hydrodynamic performance in aquatic snakes during strikes, finding that aquatic snake shapes minimize drag and added mass.
