Megabalanus tintinnabulum
Megabalanus tintinnabulum, from Philippines, in a green high gloss wood base.
Megabalanus colonies can reach big size groups, they live attached to rocks and dead coral in watched areas, sometimes attached in boats.
That is the reason why this species can be found in all Indo-Pacific but also in some areas of South Atlantic. Due to the incredible forms and colors they make excellent bizarre decor items.
