INTRODUCTION
During a NIVA (Norwegian Institute for Water Research)
environmental monitoring cruise along the Norwegian
Skagerrak coast, a 16 mm long specimen of the foraminifer
Pelosina arborescens Pearcey, 1914, was found in light brown,
bioturbated, soft muddy sediment collected with a Gemini corer
on 29 May 2008, in 350 m water depth SE of Arendal, Norway
(58( 24.177' N, 9( 01.648' E). In an effort to pull the individual
out of the sediment with forceps, it was accidentally cut into two
separate parts (the `root' and the dendritic part). The two pieces
were isolated in a 180 ml, 72 mm diameter, plastic container
with about 1 cm of sea water and stored in a fridge at
near-ambient temperature (about 7(C). On return to the lab
four days later (2 June), the two test-pieces had rejoined in their
original position and were photographed using a Nikon Coolpix
