Shark biology breakthrough: Study tracks tiger sharks to Maui mating hub

A team of shark researchers from the University of Hawaiʻi at Mānoa has solved a long-standing mystery, identifying the first-ever documented mating hub for tiger sharks, Olowalu, Maui. This challenges the conventional understanding of tiger sharks as purely solitary animals, revealing a predictable seasonal convergence of mature males and females that coincides with the humpback whale calving season in Hawaiʻi.

An amazingly large proportion of my "Blue Planet" class answered 'adamantium' for the multiple-choice question "Sharks and rays have skeletons made out of ____________." #oceanography #chondrichthyans #anatomyfail
Ripley's Aquarium #Toronto has this great ray exhibit, with cownose rays, eagle rays, skates, bonnethead #sharks and others. Great views of such complex yet also hilariously goofy animals. Rays aren't shark (as I was taught) but the shark sister-group. #aquariums #chondrichthyans #fishes
