The rare & beautiful violet sea snail - a predator of Portuguese Man O’War & by-the-wind sailors. It lives its whole life at the surface of the open ocean, using a bubble raft to stay afloat. It’s normally more common in warmer waters but occasionally seen here #marinebiology #marinelife #oceanlife

A mauve stinger #jellyfish in front of an avenue of yellow #seaweed. This from last autumn when we had huge blooms of these jellyfish - by contrast I’ve not seen a single one this year. #CornishWildlife #MarineLife #UnderwaterPhotography

Very fortunate to find another rainbow #seaslug the other day. This was the smallest I’ve seen - about the size of a grain of rice (next to my fingertip for scale). #cornwallwildlife #nudibranchs #ukunderwater #marinelife #uwphotography

Sea fog around the #Cornwall coast this morning at sunrise. Another stunning start to the day! #shotoniphone #cornishcoast #ukcoast

Cuttlefish changing colour over the sand - this is the same #cuttlefish but the sequence of photos shows how it can change its colour and texture for both camouflage and communication. #marinelife #underwaterphotography #marinebiology

Recent beautiful autumn weather & spring low tides makes for a great chance to find wonderful #rockpool creatures - like these blue-rayed limpets, tiny cushions star (both less than 1 cm in size) and star ascidians. #marinelife #underwaterphotography #shotoniphone #ukunderwater #britishwildlife

Blue-rayed limpets just beneath the surface. They often gather in groups this time of year on the lower kelp to weather autumn storms. #shotoniphone #uknature #underwaterphoto #marinelife #marinebiology

Back in the water in #cornwall after quite a long time out and lovely to see some #cuttlefish again. Very autumnal now and pretty rocky underwater! #marinelife #underwaterphotography #britishwildlife

About a year ago we had huge blooms of these beautiful (but painful) mauve stinger #jellyfish around the #Cornwall coast. On one day strong onshore winds washed them into the lower #rockpools. #marinelife #ukunderwater #underwaterphotography #marinebiology

Two tiny #seaslugs from Anilao in the Philippines: Favorinus tsuruganus, which feeds on the eggs of other sea slugs, and a Shaun the sheep nudibranch. Amazing how tiny these creatures are, barely visible to a naked eye. #marinelife #nudibranchs #underwatermacro #underwaterphotographer #marinebiology

Have you ever seen an #octopus clean and then use the toilet? This individual was outside its den so I set a #gopro to record its behaviour. From Patmos, #Greece. Plenty more film and photos to follow if the trip. #marinebiology #marinelife #underwaterfilming #wildlife

Recently back from a holiday in #Greece, Patmos Island with a bunch of videos and photos from underwater. One of the highlights was the wonderful #octopus. #shotoniphone #marinelife #underwaterphotography

A beautiful Polycera #seaslug in the shallow waters in a lower #rockpool in #cornwall. Love seeing these creatures. #underwaterphotography #ukunderwater #marinelife #nudibranch

Interested in using your smartphone for #underwater film and photography? I wrote a blog about it and the DiveVolk housing and lenses www.wildlifevision.com/blog/divevol... #iphonephotography #shotoniphone #divevolk #underwaterphotography #uwphotography

Some compass #jellyfish from the last week or so in #cornwall. They’ve come and gone a lot this year and conditions in the water have been very up and down again, with huge jumps in water temperature. #marinebiology #cornwallunderwater #underwaterphotography #marinelife

Some #macro shots of little crabs in the #rockpools - a baby edible crab and common hermit crab. Taken on an iPhone with a DiveVolk housing and macro lens. #underwateruk #marinelife #underwaterphotography

I wrote this article for Reflections to accompany some of my images on the changes happening to the wildlife around the Cornish coast including some of the new species we’re seeing here #marinebiology #marinelife #ukunderwater #britishnature #cornwallcoast www.reflections.site/stories/how-...

A tiny Facelina auriculata #seaslug from a little earlier this year in a #rockpool. One of the most beautiful species we get here. #marinelife #underwaterphotography #ukunderwater #ukwildlife

Some more #underwater scenery from the spring here in #cornwall

Very happy to have seen my first crystal jelly of the year - they were once rare to see in the uk but are now common around #Cornwall in the summer. #marinelife #jellyfish #ukwildlife #underwaterphotography #marinebiology

Took a bit longer this year but finally saw my first #jellyfish - a stunning blue jelly #cornwallcoast #marinelife #ukunderwater #underwaterphoto

The #seaweed is looking beautiful right now around the #cornwall coast. This is rainbow wrack, which is a bright iridescent blue-green when it catches the light #underwaterphotography #ukunderwater #marinelife #marinebiology

It’s raining this morning but we’ve had beautiful weather lately in #cornwall and the underwater environment is bursting with life. #ukunderwater #marinewildlife #marinelife #underwaterphotography #uknature

The comb jellies have arrived inshore in #Cornwall now - always amazing to watch them shimmer with their iridescence in the sunshine. #ukunderwater #marinelife #underwaterphotography #ukwildlife #marinebiology

A little stalked jellyfish in a #rockpool just beneath the surface. Apparently these kaleidoscope ones can cartwheel to new seaweeds when they want to move! #marinelife #ukunderwater #underwaterphotography #ukwildlife #uwphoto

Beautiful conditions the other day and lots of life returning to the shallow waters around Cornwall #marinelife #uwcornwall #ukwildlife #underwaterphotography #seaweed

Not long until these #jellyfish hopefully return to the waters around #Cornwall - wonderful things to photograph #underwaterphotography #marinelife #ukunderwater

Beautiful weather and #underwater conditions lately and lots of spring #wildlife and the kelp looking amazing again #ukunderwater #marinelife #cornwallcoast #underwaterphotography

A few more #seaslug photos - these ones of a Polycera sea slug crawling around the #rockpools recently in #Cornwall. #ukunderwater #underwaterphotography #marinelife

Delighted this image of a rainbow #seaslug has just been awarded in the British Wildlife Photography Awards: an in-camera double exposure - one macro image of the slug combined with a fisheye split shot of the kelp environment at low tide. #ukunderwater #marinelife #britishwildlife #underwaterphoto

A couple more photos of the incredible rainbow #seaslug that’s been showing up around #cornwall lately. #marinelife #ukunderwater #underwaterphotography #ukwildlife

A few clips from last year of some of the charismatic #wildlife we get locally in #cornwall. #marinelife #marinebiology #ukunderwater #ukwildlife #freediving #ukdiving

Spring is a great time here for #seaslugs as they become a lot more common and easy to find, especially in the #rockpools around #cornwall Here’s a tiny Facelina auriculata and a Polycera #marinelife #ukunderwater #underwaterphotography #marinebio

A beautiful morning again in #cornwall #seascapes #sunriseoftheday #cornwallcoast

Fluorescent hermit #crabs - one of the species we get locally glows under ultraviolet light, like many marine animals. Whether there’s any function to this is mostly unknown still. #marinelife #marinebiology #ukwildlife #ukunderwater #rockpools #tidepools

Fantastic low spring tides at the moment and lots to see! Also starting to look spring like beneath the waves now too with the kelp growing back and looking fresh #marinelife #ukunderwater #underwaterphotography #uknature #seaweed

Very happy to have had three images awarded again in the Underwater Photographer of the Year competition. There’s always lots of incredible photos to check out among the winners: underwaterphotographeroftheyear.com/winners/upy-... #underwaterphotography #marinelife #ukunderwater #wildlifephotography

An orange-clubbed #seaslug on pink hook #seaweed in the rock pools around Falmouth. Plenty of sea slugs about now as spring arrives. #marinelife #cornwallcoast #britishwilldife

Very happy to have won silver place in the over-under category of the DPG masters #underwaterphotography competition - mauve stinger #jellyfish in a tidal pool, with yellow seaweed & gloomy skies All winning photos & videos here www.underwatercompetition.com/Competitions... #marinelife #ukunderwater

Blue-rayed limpets often gather on the kelp over the autumn and winter here. They’re tiny, about 1 cm long each, and nobody knows why they have such incredible blue markings #underwaterphotography #ukunderwater #marinelife #britishwildlife #cornwall

Rainbow wrack #seaweed (also called magic seaweed) is beginning to grow back in the #rockpools as spring approaches. It’s the most incredible blue-green iridescent colour, especially the fresh shoots #ukunderwater #underwaterphotography #marinelife #uknature

A pair of Coleman’s shrimp from #Anilao in the Philippines, sitting on their fire urchin home #marinelife #scubadiving #wildlifephotography #underwaterphotography

Can you believe this tiny cushion star is just 1 cm in size? They are among the smallest and most colourful of all starfish and live in the upper shore #rockpools here in #Cornwall. The red spots on the very end of the arms are eyes! #marinelife #seacreatures #underwaterphotography #britishnature

One of the smallest #seaslugs around, this is the red Doris - it’s about the size of a grain of rice. Great to see the sea slugs reappearing here now spring is coming #marinelife #marinebiology #underwaterphotography

So happy to have found this amazing rainbow #seaslug yesterday. They only started to appear in the UK in 2022 and this is the second time I’ve come across them - the colours are unreal. #underwaterphotography #ukwildlife #marinebiology

Here’s some magic #seaweed (rainbow wrack) to brighten a dull winter day #underwater #uknature #freediving

2024 has flown by and despite the less than ideal weather for much of the year there have been many wonderful encounters and experiences

Scallop eyes - this one was in a #rockpool recently looking back at me. They use their 100-200 eyes to watch for danger, with little mirrors at the back of each eye made from crystals that reflect light back to the retina. #underwaterphoto #underwaterphotographer #marinebiology

Here’s a first post from me with two of my favourite #underwater photos from 2024 from one of the massive mauve stinger #jellyfish influxes we had over the autumn in #cornwall #underwaterphotography #wildlifephotography #marinebiology
