I'll be getting my critter fix from my files; good thing there are so many!
These sea slaters were on the rocks at Oyster Bay, on Vancouver Island this summer.
|The antennae look like old lead pipes.|
These isopods live just above the high tide line, hiding in the cracks of the rocks in the daytime, coming out at night to scavenge for dead plants and animals or growing algae. They can be quite large, up to about 1 1/2 inches long. Most are uniformly grey; the ones we saw at Oyster Bay had a cream-coloured dotted line down the center of the armored plates.
They are in the same sub-order as our common woodbugs or pillbugs, and look very much like one, only larger and faster-moving.
|Armadillidium vulgare, our common pillbug|
And here are some intertidal isopods, also for comparison:
|Intertidal isopods, next beach up. About 1/3 the size of the sea slaters.|
|Local eelgrass isopod. About 1/2 inch long.|
