(FECYT – Spanish Foundation for Science and Technology) The fauna of deep seabed tends to be relatively unknown due to the difficulty of collecting samples at great depths. A research team from the A Graña Marine Biology Station in Galicia undertook four oceanographic expeditions in the waters off the northwest coast of the Iberian Peninsula that have led to the discovery of several new species that inhabit the abyssal plains. Now they describe two eyeless species of millimetric proportions.
