Finally, a bit of good news. Well, sort of. It is not good that plastic finds its way into our oceans and can be detected in just about every sample of water but at least it appears that microplastics do not accumulate in the aquatic food chain.
Many of us are familiar with the scenes at cleaning stations, where cleaner fish and cleaner shrimp feed on the parasites and dead tissues of their “clients.”
Under normal circumstances, sharknose gobies (Elacatinus evelynae) would set up a cleaning station at a coral reef, and use it as a base to attend to their “clients”—usually the parrotfish, surgeonfish, butterflyfish, etc— by eating the parasites and dead body tissue off their client's skin, fins and mouth.
However, at reefs with damselfish, things are not always so peaceful.
Ikelite now has an update kit that allows you to convert its underwater housing for the Sony a7 Mark IV for use with the new a7R Mark V camera.
