Aerial view of a giant beluga whale pod in Cunningham Inlet, Canada. Every year thousands of belugas migrate here so that they can have a body scrub in the shallows. This helps them to moult their dead skin, which makes them more streamlined.

CANADA WILD RYE. Hairy wild rye (Elymus villosus) has similar nodding spikes, but the awns are straight, not curved and twisted like those of Canada Wild Rye and the spikes are smaller. Also, Hairy Wild Rye is almost always found in shadier woodland or woodland edge habitat. Virginia wild rye (Elymus virginicus) has straight spikes that usually are partly enclosed in the upper leaves and its awns are straight.
