João was born in 1972 and is a raconteur with a Ph.D. in marine biology, who's been focusing his academic research on shark fisheries and conservation. A featured TEDx speaker, he began his career in Bimini, studying lemon shark behavior, then became curator of sharks at the Lisbon Zoo (a very pompous title, considering he did little more than clean their poo), researched deep-sea shark growth, and then joined the Oceanário de Lisboa, where he'd become Head Diver and Curator of Collections.

In 2006 he founded his own collections firm, Flying Sharks and, as a professor at ESTM, he teaches future marine biologists. He also started an online lingerie business (Alalunga Lingerie) back in 1998 with his first wife, and their Facebook page offers delightful discounts. Apparently he ships worldwide too, and he never shamelessly takes every opportunity to advertise his business - EVER!
