I have a few hyperfixations/special interests, but the biggest one of note lately/the one I can't shut up about (to the chagrin of literally everybody in my life) are orcas. I can't stop talking about orcas.
Orcinus orca has long been the only extant species of the genus Orcinus, however new research has supported that there are likely at least two other species - Orcinus rectipinnus (Bigg's or transient orcas) and Orcinus ater (resident orcas). These are both species found on the Northern Pacific shelf. In support, we have that the animals have different morphology, societal structures, hunting structures, acoustics, mitochondrial DNA (and several other different genetic markers), dietary differences (one is a marine mammal eater, the other specialises in salmon), and more. In 50 years of monitoring, the two species have never associated, let alone interbred.
Also very passionate about cetaceans in general and the morality and practicality of the captivity of intelligent animals, but especially marine mammals and cetaceans (such as any member of the family Delphinidae).
