Hard to believe it has been over 10 years since I discovered this NEW SPECIES of ghost shark during #AlienShark on @SharkWeek. I named the species the SeaFarer’s Ghost Shark (Chimaera willwatchi) for my hard working friends onboard the fishing vessel Will Watch. 🤩🦈

I've waited a decade to finally have the chance to work with this ghost #shark 👻🦈 legend. While we were geeking away on this giant beast, we also got word that the first and only Ghost Sharks of the World book finally has a released date. Coming to you January 2026!

Excited to have contributed to this study where we tracked 29 sperm whales in the North Atlantic! 🐳
Some traveled nearly 8000km and dove deeper then 1000m! 🛰️🌊 www.nature.com/articles/s41...
This is one of my favorite photos taken during this fieldwork of a 🐳 diving under the midnight sun 🌞
