Tosanoides obama Tosanoides obama is a coral reef fish species discovered in Papahānaumokuākea Marine National Monument, Hawaii. "Tosanoides obama" was named after former US President Barack Obama in honor of his efforts to preserve natural environments including expanding the Papahānaumokuākea Marine National Monument. It was first discovered and named by Richard Pyle, Brian Greene and Randall Kosaki in December 2016. They also noted a distinctive spot on the male's dorsal fin reminiscent of Obama's campaign logo. The fish live in small groups in holes in reefs at a depth of around 90 m. Following the discovery the size of the reserve was increased.
