Tubifex sp. in Howard Co., Maryland (9/16/2013). Details from Richard Orr: "The mud on the bottom of this temporary pond has little or no oxygen content. The pond has been dry for several days. Bloodworms (Tubifex sp.) live in the oxygen deprived mud of the dried pond. A short rain formed a few temporary pools (only 8 inches or so in diameter) at the low end of the pond. The small rain pools filled quickly with thousands of the worms supplying their red hemoglobin molecules with fresh oxygen."
