An Alternative Natural History of Sussex.
This blog shows the highlights of my day to day findings as a naturalist and ecologist living and working in Sussex. Delivered with a pinch of nihilism, a dash of sarcasm and absolutely no tweeness, here is my attempt to show natural history as it really is: Brutal, beautiful, uncompromising and fascinating...and occasionally ridiculous.
I have been studying natural history for some thirty years, nineteen in a professional capacity. I currently work in Sussex as a freelance entomologist, ecologist and botanist and specialise in nature reserve and rewilding management advice based on the interpretation of the surveys I carry out. I also run a number of identification courses. An advocate of the pan-species listing approach. My main areas of interest are birds, plants and invertebrates and a lot of my spare time is spent in the field. I am the county recorder for spiders and bugs.
I just had a quick break on the Isle of Wight before my field season started and it's amazing how much things have changed for me in just two short years. For a start, I planned the entire trip to coincide with the big low spring tides. I could not pull myself away from the coast. I barely did any terrestrial recording and my hands were barely out of the water. Two years ago though, my back was so bad, I could not have coped with turning that many rocks day-after-day, or netted that much sea weed. That's all in the past now.
I have felt my attention being pulled away from the land to the sea over the course of the last year, writing the book played a part in this but the main culprit is the unrelenting lure of the nudibranchs! On this trip I found two more species for my list, bringing me up to 14 species for the British Isles. We spent a lot of time with Mark Telfer and family in the rock pools, and probably spent more time at Bembridge Ledges than anywhere else. I absolutely loved that site, so many turnable rocks! First up was Palio nothus, a a really small green nudibranch that I only found by sweeping Wireweed and then sorting through the contents in a tray. Close-focus binoculars really help here as these things are tiny.
You really can see how small this is next to a Pheasant Shell above.
The other cracker was Amphorina farrani which I saw at Bembridge and Freshwater Bay, again by sweeping Wireweed and sorting through the material.
At Freshwater Bay, using the same method, I also found St. John's Jellyfish Calvadosia cruxmelitensis! This is only the second time I have seen a stalked jellyfish that I have got to species.
There's always so much going on in rock pools that I just don't have a clue about, I dismissed this thing as a barnacle scar but Mark looked at it under the hand lens and it's clearly alive. I needed some help on this one from the Porcupine Marine Natural History Society, as I would never have realised this was actually a bryozoan! Plagioecia patina.
And I figured this might have been some kind of a coral, but I was really surprised to find out that this is a young Deadman's Fingers Alcyonium digitatum! Look what this becomes (the second photo is from over a decade ago during a SxIFCA fish survey).
And I found this on the first night. A stoloniferan, a type of cnidarian. Amazingly just as I found this the marine biologist Roger Herbert appeared out of nowhere and helped me confirm this as Sarcodityon catenatum.
On the way back to the shore, we found a rock pool that was full of Aeolidiella alderi, there was five under one rock! This is the 3rd nudibranch of the trip.
And in the same rockpool was an adult Aeolidia philomenae. This was huge! Four or five times bigger than all the other ones I have seen. The fourth nudi of the trip.
Here is Bembridge Ledges itself at dawn...
Then for something really exciting; an entirely new habitat for me. Eel-grass or see-grass beds! We went to Seaview and met up with local expert Theo Vickers. I found a couple of new fish for me, Painted Goby and this Straight-nosed Pipefish, putting me at top fish lister on the PSL site! This green pipefish is a real eel-grass specialist. It's about 11 years since I was briefly joint top fish lister last — PSL is all about the long game.
Also there were these Peacock Fanworms Sabella pavonina, another lifer! Really common there.
And a few really large Hairy Hermit Crabs Pagurus cuanensis.
This absolute unit of a Sea Hare!
Loads of these King Scallops.
And the fifth nudibranch of the week, Acanthodoris pilosa. Found floating upside down in the incoming tide.
Look at this incredibly strange habitat! I absolutely loved it there.
And just because I can, here is some Tim Buckley.
Don't panic though, although I am about to buy a wetsuit and get into snorkelling, I have not forsaken dry land and grown gills just yet. Just yesterday, I found a super rare spider at Graffham Common and a beetle new to Sussex but that is a story for another day...
On a clear day, you can just about see the eastern end of the Isle of Wight from the higher parts of Brighton. Tantalisingly close. I have only ever been once before on a day trip in 2011. This time though, Karen and I had a week out there and, as Mark Telfer has recently moved to the island, I spent a couple of days in the field with him (and one day with Iain Outlaw). Where to begin? Nothing, quite competes with the moment you realise a wild Red Squirrel is about to run up and feed right out of your hand! So I'll start there. I was so excited to see them! Here are some more shots and a very cute video.
This all started at a place called Alverstone Mead when I was struck by how tame the Great Tits were, I put my hand out to show the nearest tit that I didn't have anything and I was gobsmacked when it instantly landed on my hand. I tried again and it did it again, we rushed back to the car for some nuts.
When tits attack!
Enough of that. Rock-pooling was pretty awesome actually. I saw four Solar-powered Sea Slugs Elysia viridis (at both Castle Cove and Freshwater Bay). I'm quite taken with these beauties, they seem to be quite common on the island. Purple is so well represented in rock pool life!
Castle Cove was pretty cool, Mark said his favourite thing to see in a rock pool would be a sea spider. I rarely see them, so wasn't expecting to find one under the next rock I turned. More Snakelocks Anemones than I have seen before, too.
The west side of Freshwater Bay has wonderful rock pools. Found this huge Painted Topshell there.
And this was a lifer. A Four-horned Spider Crab.
A few Small-headed(?) Clingfish. The overall fish count was low, with Rock Goby the commonest species, Worm Pipefish and a Ballan Wrasse were the only other fish. I didn't actually see a Shanny!
A White Tortoiseshell Limpet was nice.
But what I really wanted was a nudibranch! There were a few Yellow-plumed Sea Slugs and my back was getting very sore from turning rocks, when I noticed a very bright orange and purple blob on the underside of a rock. Could it be a nudibranch? Yes! And it was an awesome one I hadn't seen before! I am pretty sure this can be nothing other than Edmundsella pedata. Just look at it (try Googling the name too)! It was only about 5 mm long and was firmly stuck to the underside of a very deep rock, so I couldn't properly submerge it for a decent photo. The only way I could take photos of it unfurled was by pouring water on it continuously with my Ferrero Rocher container. This is my 7th nudibranch.
This is what it looks like out of the water. So be prepared when looking for these to really scour the underside of the rocks with your eyes - they're often smaller than you think. I might have to leave the plants and inverts for another post, with nearly 800 records made, we sure did get around the island. This is an amazing place for wildlife and a great place for a holiday.
