Ceresium unicolor

A Ceresium unicolor longhorn beetle in Hawaii

Ceresium unicolor is a longhorn beetle that, apparently doesn’t have a common name. An introduced species, it’s not consider to be a problem in Hawaii. I found this one walking along the railing of my lanai.

Orangespine Unicornfish

This brightly-colored fish is fairly common in shallow waters. Those orange spines at the base of the tail are reputed to be very sharp, though I have no desire to field test that. One would have to be unlucky or unwise to be on the receiving end of them. They’re intended for use in encounters with other fish.
