You may think that not much can survive in the challenging conditions of the Antarctic, but here I would like to share with you some pictures from my recent diving experiences on the West Antarctic Peninsula and introduce you to some of the creatures that live there so join me in a virtual dive in Antarctic chilly waters...

Above is my personal favourite, and the subject of my Antarctic studies: Bryozoans.
Here the underside of a rock is covered with the bryozoans Beania erecta (the peachy, lumpy stuff)
and Fenestrulina rugula (white encrusting patches) interspersed with hydroids
