American educator and zoologist Cornelia Clapp died #OTD in 1934.

Clapp was a pioneering zoology researcher and leading ichthyology scholar. Her work on the toadfish was instrumental in correcting the idea that its egg was attached by a "sucker" to the yolk stalk, as she discovered that it was instead adhered with a disc of "transparent secretion" that could be separated from the membrane.

A photograph of Cornelia Clapp (right) with students working in a zoology laboratory in Williston Hall at Mount Holyoke College in 1890. The photograph of Cornelia Clapp and her students in the zoology laboratory at Williston Hall, Mount Holyoke College, in 1890, captures a moment of academic focus and collaboration. She wears a long, dark dress with a high neckline and her hair is styled neatly, reflecting the academic professionalism of the period. The laboratory setting features wooden tables cluttered with scientific instruments, glass jars, and preserved specimens, creating an atmosphere of scientific inquiry. Students, mostly young women dressed in modest Victorian attire, are engaged in various activities—examining specimens, writing notes, or using microscopes.

The Conversation U.S.

Octopuses and #cuttlefish display intelligence rivaling some vertebrates, raising questions about animal consciousness. New research by a comparative psychologist sheds light: theconversation.com/octopuses-
#cephalopods #squid #octopus #marinebiology

The ConversationOctopuses and their relatives are a new animal welfare frontier − here’s what scientists know about consciousness in these unique creaturesAnimal welfare laws don’t protect invertebrates, but there’s evidence that some, such as octopuses, are as intelligent as many mammals – even if their cognition takes very different forms.

Green algal balls!!

Does anyone know about green algal balls?

Yesterday jo_bone posted on #iNaturalistNZ photos of what look like balls of yarn, but made of green algae, washed up on a beach north of Dunedin.

An Australian science paper from 2015, about a similar looking balls on a Sydney beach, found only four previous records from Australia of such balls on beaches.

We might need a microscope to identify the algae.

Day 5 #ArtAdventCalendar: What’s inside this cigar box? A black smoker - with giant tube worms (Riftia pachyptila) for #InsertAnInvert2024. I’ve had the idea for this #multimedia in my head for years! Cigar box, collaged papers, gouache, Posca pen, glue, washi tape.

I’ve never had the opportunity to go on a research cruise to a hydrothermal vent, though I have contributed to plans for monitoring 🧵

Three shots of a multimedia artwork: Cigar box, collaged papers, gouache, Posca pen, glue, washi tape. At the top is a shot of the inside of the box with open door. The inside is lined with dark blue washi with edges in gold. There’s cut paper artwork if a black smoker on watercolour paper painted in gouache with smoke from painted Japanese tissue. In front are several clumps of giant tube worms.

Wondering what the Bomb Cyclone on the Pacific Northwest Coast looked like underwater?

A research camera running near Bamfield on the west coast of Vancouver Island caught footage of how a pacific giant octopus rode it out. 🐙

Oceans Network Canada at the University of Victoria shares the video linked in this CBC report.

‘whether it was a positive or negative experience is still open to debate, said Kate Moran, president of Ocean Networks Canada.

"When I first looked at it I thought, 'Wow, this octopus is having a bad day, trying to hold on for dear life,'" she told CBC On the Coast host Gloria Macarenko.

"And then I talked to others on my staff who said 'Oh, maybe the octopus was just trying out this exciting new way the water was moving.' So I think everyone has to look at it themselves to do an interpretation of what was going on."‘

This marine biologist discovered a unique blue whale population in Sri Lanka: Asha de Vos is also dedicated to educating her compatriots about the ocean

"This marine biologist discovered a unique blue whale population in Sri Lanka

Asha de Vos is also dedicated to educating her compatriots about the ocean

De Vos, then a master’s student, recalls being “super excited.” What she witnessed went against prevailing dogma: Her textbooks and professors had taught that blue whales, like other large whales, embark on long-distance migrations between colder feeding areas and warmer breeding and calving areas. But seeing whales pooping in tropical waters meant the behemoths must be feasting locally."

Woods Hole Oceanographic Institution researchers use the sounds of healthy #CoralReefs to encourage growth of a new species of coral larvae
Using successful techniques from an earlier study, #acousticEnrichment continues to show promise

EurekAlert!Woods Hole Oceanographic Institution researchers use the sounds of healthy coral reefs to encourage growth of a new species of coral larvaeHealthy coral reefs echo with a chorus of grunts and purrs from fish feeding, looking for mates, or defending their territories, underscored by the persistent crackling of snapping shrimp. Larval corals use these sounds as cues to decide where to choose a home. The researchers found that now a second species of coral larvae responded to the sounds of a healthy reef played through a speaker, indicating ‘acoustic enrichment’ encourages coral to settle has the potential to be a widely applicable method among coral species for reef restoration. Golfball coral larvae settled at significantly higher rates when exposed to the sounds of a healthy reef during their first 36 hours in the water. After that window, sound had little effect. Coral reefs support more than a quarter of all marine animals, protect coastlines from strong waves and storms, and provide food and tourism opportunities for millions of people around the world. Researchers estimate that 25% of all coral reefs have been lost in the last 30 years.

Under A Tree

This picture is from Lake Bosomtwe near Kumasi in #Ghana. We would love to get in touch with people who have any knowledge of the lake and the surrounding communities, but also anybody with an interest in #permaculture, #reforestation, #marinebiology etc., as the local communities are battling with the effects of overfishing, deforestation and increasing pollution. We have a bunch of ideas and we have connections in the area, but we can’t quite do it alone

Corals are not just found in the tropics. Recently, a team from Memorial University in Newfoundland found an extensive cold-water soft coral garden in an existing Marine Potected Area. These #biodiversity hotspots need protection, so this will definitely reinforce the no bottom-trawling there. 🪸
