coccolithophore

/ˌkɒkəˈlɪθəˌfɔːr/

Definition

A type of microscopic, single-celled marine phytoplankton that is covered in reflective plates made of calcium carbonate.

Etymology

The word is derived from the Greek 'kokkos' (berry or seed) and 'lithos' (stone), combined with the suffix '-phore' (bearing). It reflects the organism's unique physical structure of carrying stone-like, calcified plates.

In the news

Their ability to be observed from space makes them an important indicator for scientists monitoring ocean ecosystems.
