SMALL SHELLS FROM CASUARINA, ABACO
The shell species below (also in the header picture) is an olive. It turns out to have potential to star in a small maritime horror movie. Capt Rick Guest, who kindly keeps an eye on my shell and other sea-related posts, writes “Interestingly, the previous occupant of the first and last shell pictured here is a major predator of the other Bivalve shells shown. The Olive shell hides under the sand by day, then emerges at night to feast upon small Bivalves, and any other available prey. One can often trace the nocturnal trails of this Olive shell in sand on calm mornings with mask and snorkel, and thrust a hand under a trails end for this fellow. When kept in an aquarium, they will consume any meat offered.” “Olive and Let Die”, maybe?

Great shots showing the different seashell textures and colors! Mother nature never ceases to impresses me.

It always surprises me how wonderful tiny shells can look for patterns and colours (or both) that are only really visible with macro use. Grains of sand are also worth examining… but I am sure you do that for every beach you post about? RH

You are right. Even if there is no glass, or pebbles, or seashells – there usually is sand! Every beach really does have its very own unique treasures.

Thanks for that Rick, I’ll incorporate the details in the main body of the post if I may – I knew olives were quite voracious, but not to that extent… Very interesting. All the best, RH
