Runner up - Lowry's sea spider
An undersea spider with a straw.
Sea spiders are tiny – less than a 1cm long – and not really spiders. They are so small that they don’t need gills or lungs – oxygen circulates by direct diffusion. Although small, most species are carnivorous and feed on soft bodied prey. A sea spider pierces its prey, such as an anemone, with its proboscis and sucks out nourishment. The difference in size between predator and prey means that the prey usually survives the attack.
