Shimmering pink light glowed in the waters of Saanich Inlet on Vancouver Island, British Columbia, in July 1968, thanks to the "bloom" of a little-known but common marine animal Oikopleura dioica, a species of larvacean. By midsummer, Oikopleura numbers in Saanich Inlet had reached the millions, turning the sea a luminescent rose.

Overall, the estuary midstream and upstream supported the highest densities of protozoans, rotifers, and most meroplanktonic larvae, whereas the estuary downstream supported the highest densities of copepods, cladocerans, ostracods, molluscs, chaetognths, and larvaceans.
