This behavior leads to an increased risk of bacterial infection and the need for painful dental work. Other orcas are seen regurgitating their food to keep busy. Some have been known to bang their head against the tank walls. On some occasions, captive orcas have rammed so fast into a ...
This makes it an excellent model to study pain behavior corresponding to osteoarthritic changes [137]. Post-traumatic osteoarthritis: non-invasive animal models For several decades, the study of PTOA has involved the use of induced/invasive models. However, the procedures of these models require ...
Typically, ciliary photoreceptor cells express c-opsins, while rhabdomeric photoreceptors express r-opsins in the membrane. However, there are many other opsin classes with cases of co-expression in a cell. The aforementioned chiton larva has photoreceptors with both cilia and microvilli (Vöcking ...

The key to successful identification of these signatures lies in identifying systematic deviations from normal behavior under similar conditions, such as season, time of day and habitat. We also show that the indirect costs of predation are not limited to vigilance, but also include (1) long, ...
Finally, we demonstrate a use-case of multi-animal DeepLabCut by analyzing 9 h (824,568 frames) of home-cage behavior of pairs of marmosets (Fig. 5a,b). We tracked by ReID on a frame-by-frame basis versus only using tracklet information. We found that the marmosets display diverse ...
to express their pain by not being active, whining, and licking. Cats on the other hand hiss and hide the injured or painful site. Thus, movement changes due to OA in dogs and cats can be better studied than smaller animals [180]. Despite their marked differences in behavior when under ...
