YouTube video by UNSW Science Light pollution and the marine world

Light pollution is an underappreciated and growing threat to marine #biodiversity. It already affects ~22% of global coastlines and can reach the seafloor.

This video, made with #UNSW, #ADSA, and #DCCEEW, highlights why marine #lightpollution matters 🌊🌐🧪

Our Mission This is "Our Mission" by Seeds of the Sea on Vimeo, the home for high quality videos and the people who love them.

We have very talented PhD students! PhD student Natalie Coy founded Seeds of the Sea, to record flowering of endangered #Posidonia australis #seagrass. Check out the video she made about it (and website) below.

YouTube video by Dana Lanceman Restoring Coastal Wetlands

A short film by PhD student, Dana Lanceman, on restoring coastal wetlands. This video depicts the emotional journey of a mangrove crab, moving from wetland degradation to ecosystem restoration. Watch and learn how to support wetland restoration! 🌊🧪🌐🦀

The world feels rough right now

So please enjoy this shrimp, filmed off Cozumel, Mexico. It may be a larval reef shrimp, but we don’t know what species or how long it lives or what it eats. The world is still full of wonder and beauty and mystery.

A hand drawn image in black and white pen showing a cross-section of a coastal landscape illuminated by light pollution. The top of the image shows vertical light lines extending into the sky, above five semi-circles that look like hills. Below these hills are horizontal lines and circles that are emitting yellow texta light lines downwards. Moving down the page, under these yellow lines is the sea surface and small boats. Under the waters surface are schools of fish outlined, and at the bottom of the page are seaweeds extending up to the surface.

Wonderful illustration by Hyunh Kim from Mariana's talk at the Valuing Darkness Symposium.

Over 20% of the world’s coastlines experience #lightpollution, yet we have limited knowledge of its impacts on #marineecology and key habitat-forming organisms 🧪🌊💡🌐

Drawing of an adorable tiny yellow flapjack octopus with flappy transparent "ears" that is wearing a small striped sea anemone on its head. The stripes are in the pink, blue, and white colors of the trans flag.

Happy #WorldOctopusDay!

Do you have your party hat (anemone) ready?

In celebration of World Octopus Day, we wanted to revisit one of our favorite cephalopod sightings, the glass octopus — Vitreledonella richardi filmed during a month-long #PhoenixIslandsCoral expedition in 2021.

Meet the “squidworm” 🦑🪱

Discovered by WHOI biologist Larry Madin and colleagues, this 4-inch-long animal was just one of roughly 6,000 new species uncovered during the Census of Marine Life, a decade-long global effort involving more than 2,700 scientists to explore and document ocean life.

A Welsh landscape. A dirt path winds toward a line of trees. Bright green grass and browning bracken either side. Blue sky above, a low morning sun. And in the distance, a large hill rises above everything.

Back in wonderful Wales for a bit! 🌳

This is magnificent! Gosh, the details. Love it!

A cute carrier crab in an aquarium. The crab is red with large claws and is carrying a white colonial tunicate on its back.

We had one of my favorite crabs in the invertebrate teaching lab today! This is Dromidia sp. a carrier crab. Their last pair of legs is modified to carry sponges and other animals as a defensive mechanism. This one is carrying a colonial tunicate. #invertebrates 🦑🦀

We love jumping spiders because they are smol, cute, active, friendly and always looking around curiously with their huge eyes. But do you know they’re also masters of mimicry? Check out the bugs they pretend to be (and some of those are really good)!💚💚

How climate change could flip marine fluxes in the Arctic: reshaping entire ecosystems The Arctic is warming faster than almost anywhere else on Earth, with the Barents Sea experiencing the most dramatic loss of seasonal sea ice. As the ice retreats and the Polar Front shifts northwards

New research shows for the first time that #ClimateChange could fundamentally alter the benthic–pelagic exchange – the flow of #carbon and nutrients between the seafloor and open ocean waters vital for food webs, marine life and carbon cycling 👇

This is figure 3, which shows arm actions and their relationship to animal behaviors.

Octopuses can use any of their arms to perform tasks, but tend to use a particular arm, or arms, for specific tasks, according to a study in Scientific Reports. go.nature.com/4pjR34k 🌊 🧪

Description of the methodology & location of Cornwall Wildlife Trust Shoresearch surveys & discovery of a new to Uk species of Nudibranch Spurilla neapolitana

A purple, grey & white Nudibranch (sea slug)

What a fabulous #shoresearchweek with #CornwallWildlifeTrust & their #marineconservation team. Whilst exploring the lower shore I found the #nudibranch Spurilla neapolitana - a first UK record! 🦑

A patiently made mixed media artwork featuring a hand sculpted clay octopus, lovingly painted to resemble the species Caribbean Reef Octopus, scientifically known as Octopus briareus. The extensive and colorful reef on this artwork is made from handcrafted corals, patiently woven glass beads set on silver wire. Slowly beaded together over countless of hours.

👋 Hey friends! I'm back & super excited to share new art with you all 🎨

🥳 🎉 in love with these colors!!

The Great Old Ones - this is something already existed in my mind when illustrating the previous cephalopods piece; and so glad I’ve completed it so now I can display them side by side💙 Never stop missing prehistoric cephalopods! Thinking about making this one a silver foiled print as well!

Three grass squid (Pickfordiateuthis pulchella) chilling in a plastic container with the arms touching the edges. They are all brown with brown chromatophores. There are also a bunch of smaller things but I don't know what they are. Probably tiny translucent shrimp or krill.

Two grass squid (Pickfordiateuthis pulchella) swimming. The one on the left is the background and has their limbs pointing up and their mantle point up and right. The one on the right is in the foreground and has their mantle pointing up and their limbs point up and left. They both have dark orange brown skin with black chromatophores and some red spots.

A Grass Squid (Pickfordiateuthis pulchella) in a transparent container. It is try at the edge, and you can see its reflection. The water is dark. The squid is translucent with most of its body being covered by yellow and brown chromatophores, with some areas just being clear. Its eyes are a silvery grey, with a green colour on the part of the eye under their skin.

A grass squid (Pickfordiateuthis pulchella) swimming. Its mantle is horizontal and it has its limbs up and back. its skin is translucent with yellow chromatophores.

I don't trust them, they are a squid in the grass...

With a mantle length of 22 mm, Grass Squids (Pickfordiateuthis pulchella) are one of the tiniest species of squid. They aren't quite as small as pygmy squids which belong to a different order.
