South Fistral beach, Newquay
Our first spring event in Newquay was a huge success. After five minutes of exploring we had already recorded a large abundance of purse sponge, Grantia compressa that covered the lower shore, numerous chitons, Polyplacophora sp and colourful anemones which lined gullies and hidden caves. The cave of dreams (first found here by shoresearch volounteers in 2014) was the ultimate highlight however, with the presence of Scarlet and Gold cup corals, Balanophyllia regia, Oaten pipe hydroids, Tubularia indivisa, Celtic sea slugs, Onchidella celtica Dahlia anemones, Urticina felina and a variety of sponges. We also spotted two juvenile Sea Hares, Aplysia punctata which marked the beginning of sea hare season!

Porth Mear, Park head
Porth mear was one of the new locations we were super excited about surveying! We got in contact with Richard Pierce, a gentleman who has been surveying the shore for over 50 years who led us to a pool that was filled with St Pirans crabs, Clibanarius erythropus, a warm water hermit crab that was rediscovered on a Shoresearch survey last year in Falmouth. Since then they have been popping up everywhere and are a key species we look for on our surveys. We discovered numerous Shore Cling fish, Lepadogaster lepadogaster, A Great grey sea slug, Aeolidia papillosa and large variety of crabs species. Another highlight was finding a gully lined with Scarlet and Gold cup corals, including a rare yellow colour morph. So exciting!

Castle Beach, Falmouth
A beautiful sunny survey in Falmouth. With such a low tide we were able to explore the lower rocky reefs and kelp beds. We recorded Green leaf worms, Eulalia viridis, bright orange breadcrumb sponge, Halichondria panicea, chitons, Polyplacophora, a Fan Worm, Megalomma vesiculosum and many hiding crabs. We even spotted a Corkwing Wrasse, Symphodus melops and a Kaleidoscope Stalked jellyfish, Haliclystus octoradiatus.Millook, Bude

This incredible rocky reef is famous for surfing but as we discovered it also has a greatAnother new location in the North of Cornwall, known for its abundance of Honeycomb worm, Sabellaria alveolata and amazing geology. The great quantity of Honeycomb worm reefs covering the area meant that bare rock was unusual and uncommon, yet the area was still rich in life! Down the lower shore we were able to identify two species of Stalked jellyfish, Haliclystus octoradiatus and Lucernariopsis cruxmelitensis, Matt found a Molgula species of sea squirt and a large estuary ragworm, Hediste diversicolor. At the end of the survey, volunteer John Blackburn found an amazing Crystal Goby, Crystallogobius linearis in a High shore pool.

Our Porthleven survey was one of our favourites! This popular surfing reef is teaming with life including huge numbers of St Piran's crabs Clibanarius erythropus and during out timed species search we identified Dabberlocks, Alaria esculenta, purse sponge, Grantia compressa and numerous painted top shells, Calliostoma ziziphinum! Throughout the survey we also discovered spotted cowries, Trivia monacha, lots of anemones, an Orange clubbed sea slug, Limacia clavigera and a long spinned sea scorpion, Taurulus bubalis. Matt used his Goby traps and was able to catch and release a Giant Goby, Gobius cobitis which is a rare and protected species under the Wildlife and countryside act 1981.

Pentewen, St Austell
We were hit by stormy, rainy weather at our Pentewen survey but that didn’t stop us! The shore was rather rocky, making it the perfect habitat for a variety of crab species and marine snails. A few smaller rock pools were lined with beautiful seaweeds, such as Bryopsis mossy feather weeds, that when magnified look like little trees. In the same pool a species of Obelia hydroid was recorded and Blennys were seen swimming under rocks for shelter.
