Nothing fascinates Monica Biondo more than the animals often referred to as the ocean’s “living jewels” — the vividly colored little fishes who dance around in its waters.

Biondo, a Swiss marine biologist, became enamored with ocean life as a child after spending many summers snorkeling along the Italian coastline. Nowadays you’re more likely to find her deep-diving into trade records than marine waters. As the head of research and conservation at Fondation Franz Weber, she has spent the past decade searching through data on the marine ornamental fish trade.

These are the colorful fish you see in home aquariums or for sale at pet stores; Biondo wants to know where they came from, how they got there, and what happened to them along the way.

Compared to the clear waters around the coral reefs she’s explored, the records on these fish are frustratingly murky. Wading through them has though provided her with clarity on her calling: shining a light on the aquarium trade’s vast exploitation of these glamorous ocean dwellers.
