Costasiella usagi was named after the Japanese word for rabbit: Usagi. The cerata of this species have thin white lines and a white tip often ending in a dark spot. These small critters are famous for their cute appearance and are a favorite subject for underwater macro photographers.
We love macro and super macro photography and especially finding rare and special critters around
our island home. We do our best in identifying all critters on this website correctly; however, we
might make mistakes that can be present on this website.
Please keep in mind that this website is created for scuba divers, underwater photographers, and
everybody interested in marine animals. This website is created and organized from a diver’s and an
underwater photographer’s point of view. That’s why we primarily group animals together in a
meaningful way for divers and underwater photographers.
