Shells of the Chambered Nautilus, Nautilus pompilius (Nautilidae) are formed by two layers. The external layer has a pattern of irregular brown to reddish brown stripes, while the inner layer (as seen in the photo) is striking white iridescent.
The iridescent material inside nautilus shells is sometimes machined into pleasing shapes and sold as “Osmeña pearl.”
A way for someone to recycle their body and help marine life. Eternal Reefs transform human remains into artificial coral reefs for marine life. They help restore the fragile ecosystems off our coasts, providing an environment that supports coral and micro-organisms.
The idea was that of two students at the University of Georgia in the 80s. The idea to help came to them when they were diving off of the Florida Keys on break and saw all the deterioration and degradation of the reefs and decided to do something about it.
You can be useful to the environment even after death.
