Today, a culvert near the hamlet of Douro still contained large numbers of Canadian Worms (Aporrectodea tuberculata) swimming under the water. The worms average about 4″ to 6″ long. On April 21st, the mass was about 6′ by 4′ by 6″ and probably included many thousands of individual worms. In one scoop of the hand, you could bring out a 100 or more. Whether this was some sort of mating swarm is not clear. The worms swim under debris, appear to go in and out of tunnels or burrows and even appear to be eating at times. This particular body of water dries up in the summer.

Location: 5th Line and Centre Road of Douro in 2cd culvert north of the Centre Line
