Mantis shrimp shells contain ultrathin polarizing materials, which could find use in optical computer chips. Christopher Intagliata reports.
We predicted that mantis shrimp have functional extraocular photoreceptors in the cephalothorax (Fig.1). First, we quantified behavioral responses of eyed and eyelessN. oerstediimantis shrimp to identify any potentially extraocular photoreceptor-mediated behaviors. We found that both eyed and eyeless ani...
Deep learning (DL) based detection models are powerful tools for large-scale analysis of dynamic biological behaviors in video data. Supervised training of a DL detection model often requires a large amount of manually-labeled training data which are tim
It is often thought that the primitive is simpler, and that the complex is generated from the simple by some process of self-assembly or self-organization, which ultimately consists of the spontaneous and fortuitous collision of elementary units. This idea is included in the Darwinian theory of ...
Researchers knew the mantis shrimp had some tricked-out peepers—its visual world consists of 11 to 12 basic colors (compared with three for humans) as well as infrared and ultraviolet light.
Visual motion cues are one of the most important factors for eliciting animal behaviour, including predator-prey interactions in aquatic environments. To understand the elements of motion that cause such selective predation behaviour, we used a virtual plankton system where the predation behaviour in re...
