Phylum cnidaria are invertebrates that are well known for their ability to sting, they have capsules in their tentacles that surround the mouth. We have around 300 different cnidaria living in the waters that surround Vancouver Island.

Many of these creatures are sessile, meaning that they attach themselves permanently at their base and do not move like the sea anemones, some can move about on a pedal disk, like a foot on a snail, and can travel great distances. Jellyfish swim and drift about with the tides and over time can move great distances too. They feed by stinging into submission their prey.

Some of our jellyfish here in the Islands waters can cause great pain along with bad infections that can resist medical treatment for a long time, caution should be used around them, especially the sea blubber jellyfish.  The one pictured here was about half a meter across the bell with some very long tentacles streaming out behind it.
