This Climate Week, join Museum scientists Nathalie Goodkin and Nikita Kaushal as they journey deep into a cave to sample stalagmites & discover what their layers can tell us about past climate in this region. Learn more ⬇️ bit.ly/4nCGDuW

Stop by the Museum from Friday, September 19, through Monday, September 29, to see how eight dioramas have been transformed. Explore our full slate of Climate Week NYC programs which are supported by Wellcome Trust, bringing health to the heart of #ClimateWeekNYC.

was v excited to see work by @danmil.bsky.social (+ many others!) featured at the @amnh.org today !!

Come one come all! Our new #BINHM exhibit is up at the #AMNH! @blackinnhms.bsky.social www.amnh.org/exhibitions/...

#DYK? The hairy frogfish can swallow prey nearly twice its own size! The “hairs” on this species' body, which resemble floating worms, draw curious prey closer… allowing the anglerfish to gulp down its next meal. Photo: khaichuinsim, CC BY-NC 4.0, iNautralist

#DYK? The short beaked echidna is one of the few mammals that lays eggs instead of bearing live young. This species is also unusually long-lived, with individuals surviving up to 50 years in captivity. This spiky critter can weigh ~15.4 lbs (7 kg). Photo: Michael Hains, CC BY-NC 4.0, iNaturalist

🚨News! Observations of a brown dwarf nicknamed The Accident have found a cloud-forming molecule that hasn’t been seen on any solar system object—helping scientists understand Jupiter, Saturn, & possibly other gas giant worlds. Learn more: amnh.link/4nA9gZZ

Mark your calendars: From Friday, 9/19, through Monday, 9/29, join us at the Museum during #ClimateWeekNYC! Details: bit.ly/4nf1sgn 🖼️Throughout the week, eight Museum dioramas are being transformed to highlight the effects of climate change on our planet. Photos: Alvaro Keding & Daniel Kim/© AMNH

Growing ~1.9 in (5 cm) long, the armored bush cricket uses powerful jaws to feed on a diet that includes leaves, other crickets, & even nestling birds. When threatened, it's able to squirt a distasteful liquid called hemolymph at foes. Photo: Nyiko Gift Mutileni, CC BY-NC 4.0, iNaturalist

Sleepovers at the Museum are back! Discover the Museum after dark before drifting off to sleep underneath the Blue Whale or surrounded by other beloved Museum exhibits. From flashlight tours of our iconic halls to scavenger hunts, & more, this unforgettable program is designed to spark wonder.

Meet Bock’s pygmy octopus! Growing ~0.98 in (2.5 cm) long, excluding tentacles, this species can be found near coral reefs in parts of the Central Pacific. It uses camouflage to avoid predators & can release a cloud of ink to distract foes. Photo: smithsonian_marinegeo, CC BY-NC-SA 4.0, iNaturalist

Behold the burrowing toad! It seldom emerges from its underground home, surfacing only a few times a year during heavy rains to breed. This rotund amphibian uses its snout to access the underground tunnels and nests of its prey, including termites & ants. Photo: arbore, CC BY-NC-SA 4.0, iNaturalist

Meet the ground pangolin! It spends most of its time on the ground, creating underground burrows to snooze in during the day. At night, it uses its long tongue to slurp up insects. To protect its sofy body from predators, it can roll up into a ball. Photo: David Brossard, CC BY-SA 2.0, flickr

Rock on💎🤘🪨

OTD in 1936, the last known thylacine—a wolf-like marsupial known as the Tasmanian tiger—died at the Hobart Zoo in Tasmania. The animal’s passing marked the extinction of its species & underscores the need to protect our planet’s wildlife. Photo: Tasmanian Archives, PD, Wikimedia Commons

Smile like Smilodon because it’s #FossilFriday! Scientists estimate that its signature teeth grew at the rapid speed of .24 in (0.6 cm) per month—double the growth rate of an African lion’s teeth. Smilodon could open its jaws twice as wide as today’s big cats.

🍎 School is back in session, and we’re ready for your next visit! Each year, the Museum welcomes around five million visitors from New York City & from around the globe, including hundreds of thousands of K–12 students and their teachers.

Behold the Cuban Tody! This quick-flying bird is an enthusiastic eater, spending most of the day searching for food like insects, fruits, & small lizards. It nests in elaborate burrows, complete with twists & turns, to discourage potential foes. Photo: Cheryl Rosenfeld, CC BY-NC 4.0, iNaturalist

Ever seen a tadpole shrimp? Members of the genus Triops, these small crustaceans grow ~1.5 in (4 cm) long. These critters have three eyes—including a primitive light-sensing organ—and also use long antennae to find food in their muddy habitats. Photo: petersturner, CC BY-NC 4.0, iNaturalist

The little pygmy possum is the smallest possum in the world! Weighing ~0.4 oz (10 g), it's about the weight of 10 almonds. This omnivore has a taste for the nectar & pollen of flowering plants: It can consume up to 7% of its body weight in a single day! Photo: Tom Hunt, CC BY-NC 4.0, iNaturalist

Meet the chocolate chip sea cucumber. It has no true brain. Instead, a complex system of neurons helps it interact with its environment through touch & the ability to feel the presence of light. DYK? There are 1,000+ species of sea cucumbers! Photo: Matteo Cassella, CC BY-NC 4.0, iNaturalist

Party like a ground sloth this #FossilFriday! During the Pleistocene, a wide array of ground sloths lumbered across North & South America. Some, like the mighty Megatherium, could have weighed ~4,000 kg—the size of an elephant!

Throwback Thursday! Do you remember the 1970s? 💃🕺Saturday Night Fever was playing at the theaters and disco was pumping at Studio 54. What was happening at the Museum? We were opening a Gems and Minerals Hall, complete with carpet, a sunken pit, and cave-like lighting.

Meet a fish with “human” teeth: the sheepshead! It can grow ~30 in (0.8 m) long & weigh 22 lbs (10 kg). Inside its mouth, you'll find molars, incisors, & grinding teeth. Specialized chompers help it feed on crabs, clams, small fish, & plants. Photo: Adam Reeder, CC BY-NC 2.0, flickr

Meet the aardwolf! It’s an insectivorous mammal that’s in the same family as the hyena. Unlike its carnivorous relatives, it’s one of a few mammals that feed exclusively on termites. In summertime, it can gobble up ~200,000 termites for its midnight meal! Photo: Josh More, CC BY-NC-ND 2.0, flickr

It's Trilobite Tuesday! Pictured is a 7-in- (17.8-cm-) long Isotelus found near Dixon, Illinois. In size and shape, this specimen bears a resemblance to trilobite fossils unearthed in upstate New York. However, its dolomite-encrusted preservation provides it with a strikingly different appearance.

Meet the giant rain frog! To survive the summer heat, this amphibian burrows underground. At about 1.8 in (4.5cm) long, it’s the largest of all rain frogs. When threatened, it can blow up like a balloon, intimidating foes with sudden roundness. Photo: Marius Burger, CC0 1.0, iNaturalist

Meet the Hercules beetle! Growing ~7 in (17 cm) long, it’s one of the world’s largest beetles & was named after the Greek hero for its ability to carry many times its own body mass. Males use their horns to grapple with and topple over opponents.

This August, over 500 high school students presented their research to more than 1,500 attendees at the NYC Science Research Mentoring Consortium Symposium. The Museum leads the Consortium, a network of 30 programs that provide mentored high school research experiences for NYC teens. 📸:D. Kim/©AMNH

It’s Fossil Friday, so let’s get a leg up on the weekend with these colossal limbs! Snapped ~1899, this archival photo from the Museum’s digital collections depicts a Museum preparator standing beside the fossilized limbs of dinosaurs discovered in Wyoming.

Not all Jays are blue—meet the Green Jay! It’s native to parts of Central & South America, with a small population in southern Texas. In the tropics, this bird can be found in humid forests, where its plumage provides camouflage among the trees. Photo: Bridget Spencer, CC BY-NC 4.0, iNaturalist

Save the date for ClimateFest at the Museum! Ahead of #ClimateWeekNYC, join us on Saturday, September 20, for a full-day celebration of science, sustainability, and community. Tickets are free for Members or with Museum admission. Details.👇

We’re so proud of our incredible interns and company partners who joined the NYC Science Research Mentoring Consortium’s Annual Student Research Symposium at the American Museum of Natural History last week! Huge congratulations to all the students and partners for this amazing achievement 🧪 🔬

Last week, our high school SUN interns presented their research at the @amnh.org as part of the NYCSRM Consortium's research symposium. Over 500 students from 25 programs participated from across the city! Our interns shared how they employed inquiry-based methods to assess urban forest health.

On 9/16, join Associate Curator of Astrophysics Jackie Faherty for a look at the dawn of a new era in astronomy. As the Vera C. Rubin Observatory (@vrubinobs.bsky.social) sends its first images back to Earth, Faherty will guide us through what makes this observatory so revolutionary. Get tickets.👇

It's Trilobite Tuesday! Look closely at this Lower Cambrian Elliptocephala. This specimen—with a chunk missing from its thorax—reveals evidence of a predatory attack. Signs of healing along edges of the bite indicate that this trilobite might have survived its brush with death.

Meet one of the smallest deer in the world: the pudú. Weighing ~30 lbs (13.5 kg), it's smaller than many domestic dog breeds. This mostly solitary herbivore builds small tunnels or burrows in the underbrush to hide from predators like pumas. Photo: Bryan Caro San Martin, CC BY-NC 4.0 iNaturalist

It's #FossilFriday! This archival image, snapped sometime before 1960, depicts duck-billed dinosaurs on display at the Museum. Also known as hadrosaurs, these massive herbivores were the dominant plant-eaters during the Late Cretaceous ~85 million years ago.

could there be any grander setting for a poster session than under the blue whale @amnh.org?? don't think so. congrats to our high school intern Rewan Youssef and her Lai lab mentor @neuro-david.bsky.social. she presented her research alongside 500 other NYC students. they will keep science strong!

Update: This Saturday, August 16, the Museum will be located at 159th St between Broadway and Amsterdam. We hope to see you at Summer Streets! 😎

☄️ New exhibition, opening at the Museum on Nov. 17! Impact: The End of the Age of Dinosaurs will explore how an asteroid impact 66 million years ago changed life on Earth forever, leading to the extinction of non-bird dinosaurs & the majority of animal and plant species.

Went and wandered around the natch (american museum of natural history) for a while today. This is an #amethyst geode on display.

Ariel Barrera’s path to a Ph.D. in paleoanthropology at @thegraduatecenter.bsky.social began with a childhood visit to @amnh.org. Now, she’s conducting fossil research in Spain and shaping our understanding of human origins.

Have you ever wanted to be an intern at the Museum? Now’s your chance: Our Museum Education Experience Program (MEEP) is looking for fall interns! Applications are open through August 24. Details: bit.ly/3Jc5XJv Photos: A. Keding/ © AMNH

Happy Trilobite Tuesday! Pictured is an enrolled cheirurid from the Ordovician of Wisconsin which could exceed 6 in (15 cm) if outstretched! The distance between its genal (or cheek) spines spans over 3.1 in (8 cm) across. For reference, a dime has been placed between its pygidial spines.

How do scientists name a newly described species? Museum Postdoctoral Researcher Russell Bicknell, who recently had a trilobite named after himself, explains!

I’m celebrating #WorldLionDay at @amnh.org 🦁

Hey, New York! This month, the Museum is participating in Manhattan’s Summer Streets. Here’s where you can find us: 🌞 Saturday, August 9: 144th St between Broadway and Amsterdam 🌞 Saturday, August 16: 180th St between Broadway and Wadsworth We hope to see you there! Photos: A. Keding/© AMNH

How does a meerkat (Suricata suricatta) keep the Sun’s glare at bay? The black rings around its eyes act like built-in sunglasses, helping to reduce the harsh sunlight in its African habitat.😎 Photo: burakdogansoysal, CC BY-NC 4.0, iNaturalist

Meet the blue tree monitor (Varanus macraei)! Growing up to 3.6 ft (1.1 m) long, it can be found only on the Indonesian island of Batanta. This arboreal reptile uses its prehensile tail—which is nearly twice the length of its body—to assist with climbing. Photo: Josh More, CC BY-NC-ND 2.0, flickr
