Great talk by @arielitristao.bsky.social using Nd isotope in cephalopod studies at CIAC2025. with @zoedoubleday.bsky.social

In case you missed it, here’s what to know about the giant cuttlefish mating migration, the risk SA’s algal bloom poses to the population, and what the SA government must consider when investigating safeguards for the species.

@zoedoubleday.bsky.social @aunz.theconversation.com

The giant cuttlefish’s technicolour mating display is globally unique. The SA algal bloom could kill them all

The SA government has convened an emergency meeting today to discuss taking cuttlefish eggs from the wild, due to the impending threat of the algal bloom which could wipe them out forever.

As the SA Government convenes an emergency meeting to discuss the threat of the toxic algal bloom to the Giant Australian Cuttlefish in the Spencer Gulf today, we asked cuttlefish expert @zoedoubleday.bsky.social about the population and why it is so special.

Harmful algal blooms linked to die-off of fur seals in the Bering Sea

Ten fur seals and hundreds of fish washed up dead on a Pribilof beach last year. New research links the die-off to warming oceans.

A harmful algal bloom of Karenia mikimotoi made dozens of surfers sick and killed seadragons, fish and octopuses on two South Australian beaches.

Sea foam is a health hazard. These bacterial smoothies can contain more harmful pathogens than a sewage treatment plant – and you wouldn’t go swimming in sewage.

Dozens of surfers fell ill after swimming in seas that turned into a ‘bacterial smoothie’ of sea foam. What was in it?

"Abortion was made legal underwater nearly 50 years ago in Salmon Roe v. Wave, yet there is still a stigma attached to what is no more serious a procedure than allowing a goby fish to clean the parasites from my gills."

If Females Could Get Pregnant, There’d Be An Abortion Clinic On Every Coral

Despite the tide of aquatic opinion flowing in favor of reproductive rights for all, marine society still gives male seahorses very little say over what happens to their own bodies. Instead, we are treated as passive baby-making machines. Meanwhile, if it were the female seahorses who could get pregnant, there’d probably be an abortion clinic […]

4. Our mission at MARIS is to ensure science is not hidden behind closed doors but rather communicated to the media and public. We not only undertake research on how to boost the readability and readership of what scientists write, we also do alot of sci comm! elifesciences.org/articles/60080

Meta-Research: The growth of acronyms in the scientific literature

A study of 24 million articles has revealed that scientists have created more than 1 million acronyms since 1950, most of which have been used fewer than 10 times.

I'm loving my new @bsky.app community, so here's a little about me: science, history, culture, and travel feed my curiosity; nature and gardening give me peace; and effective writing and communication always keeps me thinking.

I run a marine science lab in Australia and this is what we do:

I'll go back to the early 1990's to a paper that showed that a small species of Australian shark fertilize their eggs and then pause embryonic development for 7+ months. The picture is a section through the resting blastodisc stage embryo. First time every reported in a shark doi.org/10.1071/MF99...

This is a histological section through a preserved egg of an Australian sharpnose shark. The granular material at the bottom of the picture is yolk. The plain material at the top is the egg case and egg membrane. And sandwiched between the two is the embryo at the blastodisc stage. It is shaped like a section through a shallow bowl. The embryo stays at this stage for 7.5 months.
