First documented mating behaviour in blue shark. That's a nice one! #elasmo #sharkscience #marineconservation
First documentation of putative mating behavior in blue sharks (Prionace glauca) reveals a potential reproductive area in the Northeast Atlantic
Abstract. Reproductive behavior in sharks remains poorly understood, with direct observations of mating reported in only a few species. The blue shark (Prionace glauca) is a widely distributed, placen...

Imagine looking at the distribution of the allelic coverage fraction at heterozygous calls in an indivdual and getting this distribution 👇 😱😱😱
