Rhinecanthus aculeatus has many common names: blackbar
triggerfish, lagoon triggerfish, Jamal, and Picassofish. It also
has a nickname: humuhumu, from the Hawaiian humuhumunukunukuapua'a
for triggerfish with a snout like a pig. Whatever the name, it's
found in coral reefs where it eats whatever passes by: worms, small
fish, sea urchins, crustaceans, and coral. It's an energetic
swimmer, and aggressive defender of eggs and living space.
