Bucket with mini gems on Texel beach
Thursday, March 5th, 2015
It looks like a red coralline little fan. But this phenomenon is a graceful foraminifer, a single-celled organism with a calcium carbonate skeleton. It’s called Miniacina miniacea. Photographer and Ecomare assistant Sytske Dijksen found it on the Hors on Texel, near beach post 7. It is the first time that Miniacina miniacea was found in the Netherlands. Sytske is often found on the beach, rain or shine. There’s lots to explore. This time it was the discovery of a blue bucket associated with a lobster basket.
Plant or animal?
It is sometimes difficult to tell whether a single-celled organism is a plant or an animal. Scientists often use the term animal when an organism has no chlorophyll. Single-celled animals are in the category zooplankton. Miniacina miniacea has no chlorophyll, so you could see it as an animal. With its ‘feet’ it gathers food. In the picture it may look a lot, but in reality Miniacina miniacea is only 1 to 2 millimeters.
