Dynamic gap crossing in <i>Dendrelaphis</i>, the sister taxon of flying snakes Open
Arboreal animals commonly use dynamic gap-crossing behaviors such as jumping. In snakes, however, most species studied to date only employ the quasi-static cantilever crawl, which involves a whole-body reach. One exception is the paradise …

A Year at the Forefront of Gliding Locomotion Open
This review highlights the largely understudied behavior of gliding locomotion, which is exhibited by a diverse range of animals spanning vertebrates and invertebrates, in air and in water. The insights in the literature gained from Januar…

Air sacs are a key adaptive trait of the insect respiratory system Open
Air sacs are a well-known aspect of insect tracheal systems, but have received little research attention. In this Commentary, we suggest that the study of the distribution and function of air sacs in tracheate arthropods can provide insigh…

Transient use of hemolymph for hydraulic wing expansion in cicadas Open
Insect wings must be flexible, light, and strong to allow dynamic behaviors such as flying, mating, and feeding. When winged insects eclose into adults, their wings unfold, actuated hydraulically by hemolymph. Flowing hemolymph in the wing…

Reconsidering tympanal-acoustic interactions leads to an improved model of auditory acuity in a parasitoid fly Open
Although most binaural organisms locate sound sources using neurological structures to amplify the sounds they hear, some animals use mechanically coupled hearing organs instead. One of these animals, the parasitoid fly Ormia ochracea ( O.…

Mallard landing behavior on water follows a -constant braking strategy Open
Many flying animals use optic flow to control their flight. During landing maneuvers, pigeons, hummingbirds, bats, Draco lizards and bees use the -constant braking strategy. This strategy regulates the approach by keeping the ratio of dist…

Material properties of skin in the flying snake<i>Chrysopelea ornata</i> Open
In snakes, the skin serves for protection, camouflage, visual signaling, locomotion, and its ability to stretch facilitates large prey ingestion. The flying snakes of the genus Chrysopelea are capable of jumping and gliding through the air…

Isometric spiracular scaling in scarab beetles—implications for diffusive and advective oxygen transport Open
The scaling of respiratory structures has been hypothesized to be a major driving factor in the evolution of many aspects of animal physiology. Here, we provide the first assessment of the scaling of the spiracles in insects using 10 scara…

Dynamic movements facilitate extreme gap crossing in flying snakes Open
In arboreal habitats, direct routes between two locations can be impeded by gaps in the vegetation. Arboreal animals typically use dynamic movements, such as jumping, to navigate these gaps if the distance between supports exceeds their re…

The aerodynamics of flying snake airfoils in tandem configuration Open
Flying snakes flatten their body to form a roughly triangular cross-sectional shape, enabling lift production and horizontal acceleration. While gliding, they also assume an S-shaped posture, which could promote aerodynamic interactions be…
