The Many Legs At The Tidal Pool

This post will be the last of my photos and videos from the tidal pools at Cannon Rocks, for now. The discoveries have been amazing and I will definitely be crawling over these rocks again. I hope to be fortunate enough to stare into tidal pools for many years to come.

One of the biggest highlight, for me, was finding this amazing little Cuttlefish.

I think this is a Tuberculate Cuttlefish (Vratjies Inkvis - Sepia tuberculata) hiding under a rock

I was busy filming an Octopus (below) when I noticed that one of the grey stones at me feed wasn't were it was last time I checked. At closer inspection it turned into this amazing little animal. What a sweetheart!

A close relative, and always a treat to see, is the Octopus.

I think this is a Common Octopus (Gewone Seekat - Octopus vulgaris)

I'm always amazed at how effortlessly members of the Cephalopoda can change color!

There are also plenty of anemones to be found amongst the rocks.

Some kind of Sea Anemone

Another group of creatures that likes to stick to the sides of the rocks are the Seastars. Some of them can growing fairly large. I definitely don't want to step with my bare feet on one of these!

The Spiny Starfish (Stekelrige Seester - Marthasterias glacialis) is quite intimidating...

The Brittlestars on the other hand are much more, well, brittle compared to the Seastars. From what I can tell they also move around much faster, at times almost crawling like a spider.

The Brittlestars might look spiderlike, but at first glance the Sea Spiders seem to be the real deal.

However when you look closely it becomes clear that Sea Spiders aren't true spiders either.

Don't be alarmed, there are indeed true spiders living in the tidal pools as well. They like to feed on isopods and amphipods.

It would appear that eight seems to be a good number of legs... If it can work for many of the creatures mentioned above then why not also for a Crab? And in fact it does work, crabs have eight (walking) legs as well - if you take some liberties and count the pincers as arms.

I'm particularly fond of Hermit Crabs, probably as a result of being a bit inclined to hermit-like tendencies myself. :)

I've always had a soft spot for Shrimp. In fact I can't get myself to eat prawn / shrimp because they look too darn cute! I like the zebra striping of these Sand Shrimp. They are also semi-translucent.

In these last few blog posts I've only shared a small percentage of the critters I encountered in the tidal pools. This is only a tiny fraction of the diversity of life found in a small stretch of coastline. I don't know what the future will bring, but I truly appreciate the privilege to be able to explore these mazing tidal pools in the here and now.
