Legs as gills, guts as a heart: plumbing the secrets of sea spiders puts DBS in the news
Sea spiders (image: Tim Dwyer) grow to Frisbee-size in the frigid waters of the Antarctic, using pores on the surface of their long legs to "breathe" in this oxygen-poor environment. But how the sea spiders circulate that oxygen was mysterious, as they lack a strong heart and advanced circulatory system. OBEE Assoc. Prof. Art Woods and colleagues made a splash recently by reporting that the guts of sea spiders (uniquely) double as auxiliary hearts, with the movement of food washing blood throughout their bodies. Read more about the study in Science News and more about sea spiders and polar gigantism here. More DBS News.
