Orangespine Unicornfish (umauma lei)

Naso lituratus


No visible horn on this unicornfish, but beware of the forward facing spines on the tail, which are bright orange and very difficult to photograph. They just look like patches of orange but are very sharp. Grows up to 18 inches long.


Common in shallow water, it feeds on leafy seaweeds. There didn't seem to be any leafy greens where this one was swimming so I am not sure what he was feeding on that day!


The beautiful Hawaiian name combines to mean chest garland.

Such interesting trailing filaments on the tail!

Okay, I found one of my photos that shows the forward facing orange spines sticking out from the body just before the tail.
