A Bit Of Flotsom...

In the ocean, any hard surface will be colonized by encrusting organisms. This basketball must have spent a few weeks or more drifting. It's got a distinct waterline which means it mainly floated in one position instead of rolling around willy-nilly.That was probably helped by the counterweighting as more algae and gooseneck barnacles attached to it on the wet (green) side.

The ball was also used as a perch by seagulls. If you look at the dry side (shadow side) you can see the light and dark streaks of sea gull "poo" running down the sides.

And even though they left no evidence, you can bet that as it floated, a variety of small fish swam close beneath it, trying to avoid larger predatory fish.

In the big blue, any structure is precious.
