Non-conceptive sexual behavior (NCSB) is phylogenetically widespread, having been
documented in 35 of the 87 extant cetacean species, but function and form of NCSB have …

While the ontogeny of beluga (Delphinapterus leucas) socio-sexual behavior has been
documented in animals between 37-and 108-months-old, the first 36 months of life are yet to …

Play is an important indicator of physical strength, cognitive functioning, and overall welfare
for animals. Performed independently or cooperatively, play provides animals, including …

Although observed in animals from various taxa, object play is not well studied. While
studying object play in managed care belugas (Delphinapterus leucas), we noticed that, in …

The majority of cetacean research suggests a right side/left cerebral hemisphere bias for
processing visuospatial information and a left side/right cerebral hemisphere bias for …

Belugas (Delphinapterus leucas) engage in many forms of play (eg, object, water,
locomotor), but no play is quite as curious as the unusual form of cooperative social play …

Mating is critical to the propagation of cetaceans, and while much of this system is
biologically hardwired or uses innate behavioral systems (see Hogan, 2001, for details on …

A number of odontocete species have been cared for by humans for multiple decades,
including but not limited to pilot whales, killer whales, Commerson's dolphins, bottlenose …

Tooth rake marks are usually used as an indicator of received aggression in odontocetes
whose social interactions are difficult to observe directly. Photographic data from five …

Successful copulation is necessary for the continuation of many species, but the courtship
behavior (ie, vocal and behavioral displays) leading to a successful copulation can vary …
