Julian Gunther

Big Fish Expeditions Trip Leader

Julian was born in Rio de Janiero, Brazil, and was immediately drawn to the water.
Currently a resident of California, he maintains a particular affinity for animals that inhabit temperate and cold waters.

A self-proclaimed “water-junkie”, his curiosity and thirst for knowledge led him to partner with the Marine Conservation Science Institute in their Great White Shark Identification Guide and their ongoing project tracking Great White Sharks at Guadalupe Island, Mexico (he’s even got a shark named after him).

His footage has been featured on Discovery’s Shark Week, Nat Geo Channel, MSNBC, the Weather Channel, Monterey Bay Aquarium and ad campaigns by GoPro and Captain Morgan.

Fluent in English, Spanish and Portuguese, Julian is always up for sharing ocean-related stories over a pint.
