Photoreceptor genes in a trechine beetle, Trechiama kuznetsovi, living in the upper hypogean zone

This study identifies photoreceptor genes in a subterranean beetle, showing it retains photoreception ability despite a vestigial eye.

Embodied Latch Mechanism of the Mandible to Power at an Ultrahigh Speed in the Trap-jaw Ants Odontomachus kuroiwae

This study identifies the fine structure of the latch mechanism in the mandible of trap-jaw ants, revealing how it enables ultra-fast movements through energy storage and release.

Descending and ascending signals that maintain rhythmic walking pattern in the cricket

This study investigates how descending and ascending signals mediate walking gait patterns in crickets by cutting nerve connections between ganglia.

Serotonergic control in initiating defensive responses to unexpected tactile stimuli in the trap-jaw ant Odontomachus kuroiwae

This study shows that serotonin modulates defensive behavior in trap-jaw ants, with 5HTP and 5HT affecting defensive turn initiation, while DA and OA have lesser roles.

Generalized locomotion of brittle stars with a flexible number of arms

The paper investigates how brittle stars with varying numbers of arms coordinate locomotion, finding a common mechanism involving a front position and synchronized arm movements.

Three-dimensional morphological analysis of the dynamic digestive system in the green brittle star

This paper uses micro-CT and instant freezing to visualize the 3D morphology of the green brittle star's digestive system during movement, revealing dynamic changes in the stomach structure.

Five breaks synchrony while six keeps synchrony: individual difference in the coordinated pattern of five- and six-armed brittle stars

The paper studies movement coordination in brittle stars, showing that morphological differences between five- and six-armed individuals lead to distinct synchronization patterns in their movement.

Excretion initiates walking in the cricket Gryllus bimaculatus

This study shows that excretion triggers forward walking in crickets, with specific gait changes and neural circuit involvement.
