This is a rather nice video with a home-made feel to it. It presents a quick view of the American Museum of Natural History in New York, starting on the subway platform (filled with lots of beautiful tile art, all of which I've photographed and shared on my blog). (I noticed that they seem to have finished refurbishing their Indians of the Pacific Northwet exhibit).
The AMNH is a scientific…

Despite being the largest fish species in the world, measuring over 40 feet in length and 35 tons in weight, whale sharks are quite mysterious. We know they are plankton filter feeders, and we recently…

Years ago, when Zoologist Mike Dickison was in the early stages of his PhD, he gave a joke presentation at a graduate student conference on the taxonomy and evolution of a giant flightless bird. It was the sort of thing you'd see at any conference on avian evolution: a Latin name, reconstructed skeleton, possible place on the great evolutionary tree of birds. The tone…

Only thirty years ago, tens of millions of White-rumped Vultures, Gyps bengalensis,
were flying the skies of Asia. They are now classified as Critically Endangered.

This video tells the story of speciation in Central Africa's roiling, rapid Lower Congo River. This river is home to an extraordinary assortment of fish -- many truly bizarre. This new video by Science Bulletins, the American Museum of Natural History's current-science video program, features Museum scientists on a quest to understand why so many species have evolved here.

This video is the first of a new series of behind-the-scenes looks at the collections at the American Museum of Natural History. In this video, Melanie Stiassny, Axelrod Research Curator in the Department of Ichthyology, takes us through the Museum's vast collection of fishes.
The Department of Ichthyology, one of the four departments within the Museum's Division of Vertebrate Zoology, houses a collection that comprises more…

I'm happy: another book review of mine was just published, this time, by Science magazine. This book, Here Be Dragons: How the Study of Animal and Plant Distributions Revolutionized Our Views of Life and Earth (Oxford University Press: Oxford; 2009), is by Dennis McCarthy, a researcher at the Buffalo Museum of Science in Buffalo, New York. In short, I liked the book and I thought it was generally well-…

Bird watchers (especially those who do most of their birding by ear) will particularly enjoy this video: Peter Tyack of Woods Hole talks about a hidden wonder of the sea: underwater sound. Onstage at Mission Blue, he explains the amazing ways whales use sound and song to communicate across hundreds of miles of ocean.

This fascinating video shows that Calvin Klein's "Obsession for Men" is NOT just for men! This is a great example of how careful observation of captive animals' behavior is directly impacting research with wild animals. When biologists at the Bronx Zoo started spritzing "Obsession for Men" cologne near heat-and-motion-sensitive cameras, the tigers, snow leopards, jaguars and cheetahs…

sciencepunk | May 31, 2010Treehugger reports on the work of marine scientists at Brazil's Guaruja Aquarium, who have added a plastic window onto a shark egg so they can watch the fish develop.
In the photo above you can see the fetal bamboo shark attached to a large yolk sac. The video below gives a better view.
After noting that the unborn shark was unaffected by the window on its neonatal world, researchers removed the entire animal from its purse and allowed it to grow inside a perspex container. The work will help shed more light on how young sharks develop, an understanding of which is crucial to the…

An Australian Aboriginal rock art may depict a giant bird that is thought to have become extinct some 40,000 years ago, thereby making it the oldest rock painting on the island continent. The red ochre drawing was first discovered two years ago, but archaeologists were only…

Perhaps you'd like to see what some of those creatures are that are being endangered by the oil spill in the Gulf of Mexico? This lovely video provides a glimpse of the "gelata": siphonophores, jellies and other soft, gelatinous marine animals that lack bones and brains, but nonetheless, comprise much of marine life. They are otherworldly creatures that glow in the dark…

This fascinating video captures a glimpse of the weird and wonderful animals that live in the aphotic zone. The aphotic zone (aphotic from Greek prefix á¼- + Ïá¿¶Ï "without light") is the portion of a lake or ocean where there is little or no sunlight. It is formally defined as the depths beyond which less than 1% of sunlight penetrates. Consequently, bioluminescence is essentially the only light found in this zone. Most food comes from dead organisms sinking to…

Douglas Adams was the best-selling British author and satirist who created The Hitchhiker's Guide to the Galaxy [DVD]. In this talk at UCSB recorded shortly before his tragic and untimely death, Adams shares hilarious accounts of some of the apparently absurd lifestyles of the world's creatures, and gleans from them extraordinary perceptions about the future of humanity.
