Shoresearch Week 2015 day 3 Polzeath Highlights in Photos


 Polzeath on Cornwalls north Coast is an incredible shore,  it is exposed to huge Atlantic swells yet its gullies and caves provide habitats that are rich in marine life.  Filter feeders thrive here thanks to nutrients coming from the camel estuary. The place is teeming with diversity!
The weather could not have been better - flat calm (very rare for this site) and no wind plus a huge low tide thanks to the Supermoon and high pressure further pushing the water down
A vast area of kelp dominated reef was exposed and explored for the first time by the Shoresearch team!

Heading to the North end of the Bay 
Laminaria hperborea kelp and dulse covered a huge area - the rocks below were carpeted in Corallina and pink plates - Mesophylum lichenoides 

Jake and Mango exploring some low tide crevices!

Montagus sea snail - a small fish related to a lumpsucker was found in low shore pools 

This beautiful tiny sea slug Polycera quadralineatus  was found in a large mid shore pool on Cystoceira seaweed. 

Non native seaweed Asparagopsis armata was found for the first time at this site. Its spear like branches act like velco allowing it to be spread accidentally around the coast. 
This is the first record of Corella eumota the orange lipped seasquirt at this site too. This is another non-native that is rapidly spreading around the coastline.  found by Jake Meyers

Probably Sabellaria worm tubes! They can be found at many sites but for some reason rarely form colonies in Cornwall - except of course for along the coast of North Cornwall from Crakcington haven and past Bude

Long spined sea scorpion Taurulus bubalis

This is a favorite large pool higer up the shore where jake found the tiny Polycera nudibranch

Here is a cool crab  - totally covered in camoflague! This is Pisa armata -or Gibb's spider crab still rarely recorded in Cornwall -we found two males and a female.

Green leaf worm (Eulalia viridis)  Pink corraline encrusting algae, Corralina elongata , a pheasant shell and  some saddle oysters.
Long horned porcelain crab - Porcellana longicornis
Unidentified small polychaete worm  
Upper shore pools are teaming with Bifurcaria bifurcata, tuning fork week
Blue Rayed limpet Patella pellucida
An Isopod Ideotea baltica - these were everywhere and come in a huge variety of colours! Identified by the shape of the tail

The biotope that they like - breadcrumb sponge, beadlet anemones, pink encrusitng algae

Onchidella celtica - the celtic sea slug - is a land gastropod that has become adapted to life on the shore- they only come out to feed when the tide drops out and then they are only able to feed for a limited time before becoming too dry after which they will dissapear as we found out!

It was an awesome Shoresearch!!  Polzeath is great!

Shoresearch Week 2015 Day 2, Hannafore point, Looe in Pictures

Fantastically low tide - you could easily have walked to Looe Island! 
..,.,.and how excited was I?! My first Conger eel - I've spent my life rockpooling but never found one of these before!! 40 must be my lucky year! 

what a beauty!! note the lower jaw is the same lenght as the upper jaw, much more blue /grey than a common eel and two large nostril tubes

Beautiful star ascidians Botryllus shlosseri - photo by Jenny Lord! Thanks Jenny this is definitely going in my collection!

Montagus crabs - now very common all around the Cornish Coast - rare when I was a kid. Note they vary in colour alot, this one lacks the typical black tips on its claws but it is definately a Montagu's! Xantho hydrophilus

It was nice to get into the eel grass beds although they seemed to have reduced in size since last year - lots of brown leaves suggesting the autumn die back has started relatively early. Here is a nice Stalked Jellyfish Leucernariopsis campanulata found on a sea grass frond by eagle eyed Jake Meyers.




Lots of Creephorn was found - Chondracanthus acicularis

beautiful conditions for shoresearching - Photo Jenny Lord

The Shoresearch team!! Thanks guys it was a great survey!

Supermoon provides Super Shoresearching - SHORESEARCH WEEK 2015

Cornwall Wildlife Trust volunteers were treated to the best rockpooling the United Kingdom has to offer last week on their annual Shoresearchsurvey week. The huge spring tides generated by the supermoon were amongst the lowest seen in recent years. On top of this the weather was incredible with bright sunshine and light winds and the high atmospheric pressure meant that the water was pushed even further down!

Shoresearch Week is an annual event now in its fourth year where volunteers record the marine life they find at all five of Cornwall’s Voluntary Marine Conservation Areas, at St Agnes, Polzeath, Looe Fowey and Helford.
Matt Slater, Marine Awareness Officer at Cornwall Wildlife Trust led the events,
“It was an amazing week with perfect weather and great company. Shoresearch is great because you never know what you will find and with a team of keen volunteers the chances of finding something exciting is far greater! Our marine life in Cornwall is incredible and overall we were able to record over 200 species at all five sites and a total of 47 volunteers took part.

Highlights of the week included;
• Finding beautiful colourful fan worms growing on kelp at Trevaunance Cove, St Agnes, exploring the eerie conger hole and seeing a tiny baby tompot blenny with its fluffy eyebrows!
• Finding a small conger eel on the shore at Hannafore point beneath a rock. Volunteers were able to walk nearly half way to Looe Island and were right in amongst the kelp zone, finding animals and plants you would normally have to snorkel to see!
• At Polzeath an incredibly calm sea meant we were able to access rocky platforms covered in Kelp and furbelows which we have never been able to get near to safely before. Living amongst this seaweed we found stunningly camouflaged and rarely recorded Gibbs spider crabs and a beautiful fish called a Montagu’s sea snail.
• At Prisk Cove Helford we saw bright green juvenile ballan wrasse, weird sea cucumbers, lots of green sea urchins and a wealth of other species beneath the rocks.
• At Fowey we found common starfish, cup corals and loads of Risso’s crabs – climate change indicator species whose range is moving further north.

Matt Slater continues,
“It is encouraging to note how many young people took part, Shoresearch is great fun and everyone reported that they learned a lot by taking the time to find out what is living on the shore which many people don’t get a chance to see! Many of our volunteers go on to develop a real passion for the marine world and it is exciting to be finding the marine biologists of the future!
Five days in a row of rockpooling is surprisingly hard work, reports Matt,
I had blisters on my toes from my wetsuit boots and cuts on my fingers from lifting rocks, but it was well worth it! I feel incredibly privileged to have been able to have spent the week in this way! Next week I will be in the office pressing seaweeds and identifying specimens from hundreds of photographs taken by myself and the volunteers”.
