As part of the continuing NYC Climate Week the American Museum of Natural History had another event. Multiple NGOs & agencies had information tables, there was a music act & NYC’s DEP climate leader spoke. I learned NYC is a world leader in climate policy. Thank you @amnh.org #AMNH #climateweek

🌍 We offer a special thanks to the @amnh.org for inviting us to participate in "Climate Resilience in Action," a #ClimateWeekNYC evening program highlighting on-the-ground work by local organizations across the boroughs to advance #climate and #sustainability goals. 💙

How does the gharial's snout help make it a powerful underwater predator? It’s lined with sensory cells that detect vibrations underwater. And when a fish swims into range, it can quickly whip its head sideways, meeting minimum resistance in water! Photo: George Lin, CC BY-NC 4.0, iNaturalist

Meet the coconut crab. It can span ~3 ft (1 m) long from leg tip to leg tip & weigh ~8 lbs (4 kg)! It inhabits coasts off of the Indo-Pacific Ocean. Scientists have compared its pinching power to a lion’s bite force! 🥥🦀 Photo: luca63, CC BY-NC 4.0, iNaturalist

We know that many animals are in danger due to human-caused climate change impacting their habitats. This #ClimateWeekNYC, Columbia University and Richard Gilder Graduate School Graduate Fellow Ellie Gamett explains what we can learn from the resilience of blue dasher dragonflies.

Black in Natural History Museums in now open! See it on Floor 3 in the Museum's Gilder Center. Details: bit.ly/3KfbzTS

I went to a panel discussion at the American Museum of Natural History today. The topic was effective climate communication & how US public opinion is much more concerned & open to action about climate change than is generally accepted. Thanks @amnh.org for an illuminating talk #AMNH #climatescience

🍁It’s the first day of fall, and few things make it feel more like autumn than the foliage of the red maple tree (Acer rubrum). Did you know? The deciduous tree sports something red all year round... Photo: Ashley M Bradford, CC BY-NC 4.0, iNaturalist

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
