Razor Coral (Lobactis scutaria) クサビライシ – Mushroom Coral size 17cm
This is one of the common Razor Corals in Hawaii. They are usually a single poly and not attached to the bottom. This was in a shallow reef area. Kauai 2022
I think that these Razor Corals are also Lobactis scutaria. They are a little irregular because the area gets a lot of surge, and they rolled around a bit. Kauai 2014
There are several Razor Corals that resemble this one. Miyakojima 2017
Another Razor Coral. I think that this is different than the one above it. Amami 2023
The long ones they call Tongue Coral. There are several Tongue Corals that this looks like. I find them at about 8m. Amami 2024
