The recent publication highlighting the discovery of a new reef fish in Papua New Guinea called the tubeworm dwarfgoby (Sueviota tubicola) marked an important milestone in my career: my 100th description of a new fish species, all completed during my 13 years at Conservation International (CI). (If you include the species I have both discovered and described, the number increases to over 150.)

Among those 100 fish that I have introduced to the scientific community, here are five of my favorites.

  1. The tilefish with the vanishing stripes

During our first marine rapid assessment of Indonesia’s Kaimana coastline in the southern Bird’s Head region, I found a beautiful tilefish on a deep 70-meter (230-foot) dive. This striking fish builds large communal mounds of rubble that cover its labyrinthine burrows beneath. It bears a striking resemblance to another tilefish that my fellow scientist Dr. Gerry Allen and I had described, differing only in the presence of tiger stripes on its body.

When I first encountered this fish, I had very limited time to safely stay at this depth, and I had to choose between photographing and collecting the fish. I decided to collect it, but by the time I emerged from my very long dive, the specimen had died, and its stripes disappeared! Gerry was underwhelmed and reckoned I had hallucinated the stripes on the fish. This meant I had to do yet another very deep dive — this time as the sun was going down, and our survey time running out — to properly photograph the live fish in its natural habitat. I managed to find another mound and photograph the elusive tiger pattern, and Gerry decided on the spot to name the new species after me.
