Of course we have to celebrate #WorldWildlifeDay! From 🦎 to 🪸 to 🦀, collections like ours are invaluable for showing off (and teaching about) the extraordinary wildlife around the world! #worldwildlifeday2025 #alfreddennymuseum #sheffieldmuseums

For #WorldWetlandsDay 🏞, we're thinking about the amazing species that depend on these wet and wild habitats, such as: 1: Platypus (Ornithorhynchus anatinus) 2: Northern lapwing (Vanellus vanellus) 3: Bichir (Polypteridae) 4: Water scorpion (Nepa sp.) #worldwetlandsday2025

Happy Year of the Snake! 🐍 Snakes have enormous cultural significance; in the zodiac they're associated with strategy and intelligence Our collection includes this beautiful Central American coral snake (Micrurus nigrocinctus) #yearofthesnake #Yearofthesnake2025

It's World Snow Day! ❄❄❄ This sculptured mitten lobster (Parribacus antarcticus) wants to remind you to wrap up in the cold! 🧤🧣 (It's a tropical species but it keeps its mittens to hand in case of a marine snow flurry) #worldsnowday #snowday #sheffieldmuseums

Shelly Christmas with Salpa Claus and the Shell-ves, and the rest of the Alfed Denny Museum collection! (Salpa sp.; Conus sp.; Haliotis sp.; Brechites sp.)

For #MonkeyDay we bring you: the siamang gibbon! Gibbons are monkeys, and so are you! We're apes, belonging to the Old World group of monkeys: the Catarrhini🐵🧑 Siamang have an amazing throat pouch to louden their calls, like a frog!🐸📢 (2nd📸Nngowen | Wikipedia, CC licence)

Happy #worldanteaterday! This wonderful skeleton is from a southern tamadua (Tamandua tetradactyla) With a head like a handheld vacuum, it laps up ants with startling speed. It doesn't bother chewing, and doesn't even have teeth! #anteater #tamandua #taxidermy #sheffieldmuseums

Happy #Halloween! 🦴🎃🦴 We have some classic Halloween species in our collection. Some people call them #spooky, but we think they're spellbinding! What do you think? #museumcollections #sheffieldmuseums

It's #internationalslothday! This beautiful skeleton belongs to a three-toed sloth, one of two living groups 🦥 These and the two-toed sloths independently evolved from ground-based ancestors; today's branch-clingers are actually the odd ones on the historical sloth family tree!

To celebrate #internationalsawfishday, here is our extraordinary sawfish rostrum! Sensory organs in the rostrum detect tiny electric currents generated by fish. Then the sawfish swipes its serrated schnoz at its prey to daze them for easy consumption! #sawfish

Been doing some bits recently with @BBCSheffield for their Secret South Yorkshire series. If you like learning about animals by looking at skeletons then I'd recommend a visit to @ADMsheffield. https://t.co/GGa4cfoxv0

Both our recent documentaries have been embedded into the virtual reality museum to give viewers more information about the museum and related collectors. Check out the full VR experience here! https://t.co/04rw0WUxLq

If you've visited us before you'll be aware of our Sorby Slide collection, but who was Sorby? Watch out new documentary to learn more about one of Sheffield's greatest scientific minds. https://t.co/3bIJuXGZ54

It’s #WorldOrangutanDay ! Orangutans are native to the rainforests of Indonesia and Malaysia. They are the most arboreal of the great apes, spending most of their time in trees – hence why their feet and hands are so similar and their fingers and toes much longer than humans.

We've added a new page to our website all about our thylacine skull and how it's been used in student research projects! The now extinct thylacines were marsupial carnivores native to the Australian mainland + the islands of Tasmania and New Guinea. https://t.co/FQI6YtngKh

Happy #WorldElephantDay ! Checkout these massive skulls from an African elephant(left) and Asian Elephant (right). It is rumoured that elephant skulls could have inspired the myth of the cyclops from assumptions that the large central nasal cavity was a large eye socket.

For our final #LoveParksWeek we've got some insects! Cabbage White Butterflies are a common sites in parks and gardens. The females have two brown dots different to the male. Ladybugs are familiar bright beetles with spot-like patterns. They prey on aphids, protecting plants.

In our herbarium we have several specimens collected from parks e.g. Hairy bittercress and Water Avens which highlight the diversity of park plant life, even if from a distance it all appears to be grass. In fact grasses are very diverse, with over 160 UK species #LoveParksWeek

#LoveParksWeek European hedgehogs often venture into parks at night to forage for insects. Another nocturnal park goer you can spot in the evening is the Pipistrelle bat. Rats are a common sight, and while they have a bad reputation, they mostly live in harmony with us!

Today for #LoveParksWeek we’ll be highlighting some birds from our collections. The Eurasian Wren is a familiar site with its small round body and upright tail. A rarer site is the rook, a member of the corvids, these birds tend to forage in more rural open country and farmland.
