Narwhals are quite elusive and live close to the Arctic, which means they are hard to study. Why do they have this massive tusk,…

Baby, it’s Cold Outside! Thermoregulation in marine mammals

Polar oceanic water can get as cold as about –2°C! Even temperate or tropical waters might drop as low as –1°C if deep enough. This makes you think, how do marine mammals survive arctic temperatures? In this post, we’ll take the artic plunge into thermoregulation in marine mammals. What we will learn in this post – Credit: Anaïs Remili Let’s Talk Ratios: Size matters! One way that animals can reduce heat loss is by having…

Photo-ID is the heart of whale research

Photo-ID has been around for decades: it allowed researchers to study the marine mammal populations and opened the door to awesome whale research worldwide. So what exactly is photo-ID, why is it important, and how can you gain skills in this discipline? Find out in this post. A picture says more than a thousand words Whales and dolphins’ broad distributions, underwater lifestyles, and migration patterns make them challenging subjects to study. Populations are constantly changing;…
