Sea Urchin Barrens
The Sea Urchins used to be kept in check by sea otters. Now there are so many they have eaten almost all of their primary food (kelp) on the lower parts of the bottom. The Sea Urchins now come out of the water to eat the highest growing kelps. Species: Strongylocentrotus franciscanus (Red Sea Urchin)

Blood Star With Purple Sea Urchins
I'm surprised to see the purple sea urchins out like this - I'm used to them tightly packed into cracks in the rocks. John Harvey Photo > John's Overnight Page > Haida Gwaii > SGang Gwaay > Blood Star With Purple Sea Urchins

Sea Urchin Barrons
Haida Gwaii has a sea urchin problem - their primary predator (Sea Otter) was hunted to extinction. There has been a few sightings of sea otters at the Southernmost tip of Haida Gwaii, but it's often lone males that colonize a place first so it it may be a while before a real population takes hold.

Red Sea Urchin
Strongylocentrotus franciscanus. I'm used to the much smaller Purple Sea Urchin, so I was quite surprised how large this one was when Steve hauled it on board. Tags: sea urchin

Sea Urchins Grazing
I'm pretty sure this is Diadema Genius. I'm less sure about setosum but it does match what I'm seeing on the internet. At the time, I thought these were feeding on the coral but from what I've read, they feed on algae. Species: Diadema setosum (Setosum Spined Urchin)

Small Urchin
I wish I could identify this one, but it could be either a white Urchin or a Juvenile purple and there isn't enough in this picture to be sure. Tags: sea urchin
