FAMILY : ROTALIIDAE
Pararotalia sp?
Forams are a group of protozoans
that are entirely marine, construct a lobed skeleton or "test", and
apart from a few planktonic species are found on the seabed or plants.
Some species, such as Marginopora
can grow to 20mm but the majority, like the above, are less than 1mm.
A foram can be seen in the
centre of this image. The Velutinid about to crawl over it is
approx 4mm long.

The images below are of forams
from a beach in Okinawa and are about 2mm. Some sands on beaches on these
islands are composed
almost entirely of forams and are known as "Star Sand"
