The morphology, physiology, and behavior of marine organisms have been a valuable
source of inspiration for solving conceptual and design problems. Here, we introduce this …

Although shark teeth are abundant in the fossil record, their bodies are rarely preserved.
Thus, our understanding of the anatomy of the extinct Otodus megalodon remains …

Larger animals studied during ontogeny, across populations, or across species, usually
have lower mass-specific metabolic rates than smaller animals (hypometric scaling). This …

This chapter presents a detailed review of works published on Artiodactyla endocasts and
provides a comprehensive examination of artiodactyl brain evolutionary history, including …

The reasons why some animals have developed larger brains has long been a subject of
debate. Yet, it remains unclear which selective pressures may favour the encephalization …

Most authors have identified two rapid increases in relative brain size (encephalization
quotient, EQ) in cetacean evolution: first at the origin of the modern suborders (odontocetes …

The major increase in cetacean brain size happened in the middle Miocene, about 15
million years ago, and involved the modern oceanic dolphin lineage Delphinoidea. In this …

Baleen whales are considered underencephalized mammals due to their reduced brain size
with respect to their body size (encephalization quotient [EQ]<< 1). Despite their low EQ …

Typically, investigations of animal cognition couple careful experimental manipulations with
examination of the animal's behavioural responses. Sometimes those questions have …
