A Triton snail (maybe Ranella Australasia gemmifera) at the Woody Cape |
My exploration started off with a bang! One of the very first creatures I saw was this amazing Four-Tone Nudibranch.
Four-Tone Nudibranch (Godiva quadricolor) gliding along the edge of a small rock pool |
From what I understand the nudibranch is basically a kind of predatory sea slug-like animal. It feeds on sea anemones and other nudibranch-like animals.
This encounter inspired me to try and return to the rocks at low tide on subsequent days in search of more interesting sea slug-like-things.
Blue-Speckled Dorid (Dendrodoris caesia) hiding under a rock |
The Blue-Speckled Dorid unfolded in the water |
The little dorid feeds on sponges. I believe the fluffy bits at the rear of the animal is are the external gills.
Another, even smaller, sponge feeder is the Lemon Pleurobranch.

The animal below might seem artificially similar to the sea slug-like animals above, but this beautiful little critter below is actually a tipe of Flatworm.
A species of Carpet Flatworm (Thysanozoon sp.) found along the intertidal shoreline at Cannon Rocks |
I was fortunate enough to be able to view one of these flatworms under a field microscope on a recent visit to De Hoop and my breath was taken away by just how beautiful they are.
I found another tipe of flatworm on the rocks, but this one looked a bit like a living blob of slime...
Gilchrist's Booger ergmm I mean Gilchrist's Flatworm (Planocera gilchristi) under a boulder |
The Gilchrist's Flatworm feeds on tiny animals found in the tidal pools, such as worms and crustaceans.

My attempt at filming a flatworm swimming failed, but trust me that it is something to behold. Luckily there is always next time. I'm already looking forward to visit the rock pools again and again, in the years to come.

There is still plenty more to share from the Cannon Rocks coastline, even some camera trapping, so stay tuned.
