🇦🇺🎉 We’re excited to be launching the #GreatEggcaseHunt in Australia! In partnership with @CSIRO, we're calling on citizen scientists to find & record eggcases (#mermaidspurses) washed ashore or those seen by divers. 🔎Find out more at - sharktrust.org/news/great-egg… 📷CSIRO

#GreatEggcaseHunt has reached Australia! Some eggcases have a smooth appearance. Others have ridges or keels. Some have curled tendrils to anchor to kelp/coral. Some are even corkscrew-shaped! Check out the diversity of species in our NEW ID guides sharktrust.org/geh-id @CSIRO

So many amazing critters being caught for study on the #RVInvestigator in the Gascoyne Marine park, including this #Gigantactis species that uses its lure, complete with mimic eyeball (!) 👁️ to attract prey. 👏nature. @CSIRO @wamuseum @ausmarineparks

@zoologymolly @SharkAdvocates @sharkshareGL @StellenboschUni @IUCNShark @MNetSharkTank @SharksInt2018 @SharkSpotters @2OceansAquarium @SharkWeek awesome find! what was the location of this?

Collecting #eDNA from the intertidal zone and finding lots of cool stuff, like this chimaera egg case 🐠 🦈 #zoology #environmentalDNA #SAeDNA

7 species of #Manta and devil rays occur in #Indonesian waters. They are mostly caught as #bycatch but are sometimes targeted. Populations are decreasing with all species listed as #endangered or #vulnerable (#iucnredlist). How well do u know your rays? fishIDER.org

@leplumba @realDonaldTrump As a Brit I can say: “No. BY A LOT”

I WON THIS ELECTION, BY A LOT!

While many a specimen are attributed to Wallace, it is unlikely that he accomplished this alone. @JackDAshby tells how we can celebrate the enormous contributions made by #PeopleofColour to science in the stories we tell 🐦📖 #DiversityInSTEM #Decolonise ow.ly/iT6q50C3FE4

@simondema @jmhuiee I second Morphosource! 😁

@jmhuiee I’ll look into that, thank you.

After nearly 35 years of preparing shark specimens, I have finally managed to acquire two beautiful whole Frilled sharks ( Chlamydoselachus anguineus) to prepare as skeletons. These specimens will be CT scanned first then prepared. The Holy Grail of sharks

@AmandaHay13 @WillWhitesharks @CSIRO Sure! I'll send you a copy. :)

@thegingerfish_ @WillWhitesharks @CSIRO Nice one! Can I get a copy please?

New (and my first!) paper with @WillWhitesharks & Chris Avila describing the #eggcase and juvenile of 2 #catshark species and showing how egg case morphology can distinguish between species! doi.org/10.1111/jfb.14… #GreatEggcaseHunt #eggcase #FishSci #JFB

#Serranidae are a large & diverse group of fish. They are commercially important, commonly appearing in Indonesian fish markets. See them on #fishIDER - fishIDER.org - an online #fish identification #taxonomy tool improving #fisheries #sustainability & #foodsecurity.

@BritFinucci @ElasmoBro He looks sad because he’s so weird x

The mighty Prickly Dogfish (Oxynotus bruniensis). This #deepsea #shark was named for its enlarged denticles which give it a prickly-like appearance. Enjoys feeding on the eggs of other sharks. It is the #bestshark #sharksnearme #StayHome #SelfIsolation #remotelearning

Now live: The NEW and IMPROVED #fishIDER!🥳 fishIDER.org: improving #Fisheries sustainability and ultimately #foodsecurity in #Indonesia🐟🇮🇩🐠 @ACIARAustralia @CSIRO @kkpgoid #CSIROcollections

What’s great about working at the CSIRO Australian National Fish Collection? The weird looking #fish, of course! #CSIROCollections facebook.com/142468583842/p…

@fishoscience @MotherOfRays @simondema 🤮

@thegingerfish_ @MotherOfRays @simondema Thank god we don't get them, i cant imagine that in my mouth 🤮

Copepods inside the lower jaw of a Mako shark

@fishoscience @MotherOfRays @simondema Meant to add - they go right down to the jaw bone. 😳😢

@fishoscience @MotherOfRays @simondema I’ve also seen them on makos.. total filth

@simondema Learning can happen from anyone 😉 btw, your cartilage articulations and jaws are awesome! Some real inspiration there!

@thegingerfish_ Glad to be a non-scientist and still wow! people like you. I’m humbled 😁

Rabbit holes: how a casual 1 minute conversation about #remoras over morning tea can turn into an hour+ in the lab identifying preserved specimens in the Fish Collection. Would have been easier if they were bigger! Cute little flipflop heads <3 #taxonomy at #CSIROcollections

@simondema Well I hadn’t heard of it but apparently it’s true! It is referred to in an article here: #metadata_info_tab_contents" target="_blank" rel="nofollow noopener">jstor.org/stable/2456185… thanks for sharing, you learn something new everyday!

@thegingerfish_ I once read the remoras (larger specimens) were used by fishermen in certain parts of Africa to catch other large fish and turtles. They tied a string to the remora and dropped it over the side, where it would attach itself to another fish or turtle. Myth?
