100 Years – 100 Objects: Specimens of the Dooley-Selden Expedition

The Houston Museum of Natural Science was founded in 1909 – meaning that the curators of the Houston Museum of Natural Science have been collecting and preserving natural and cultural treasures for a hundred years now. For this yearlong series, our current curators have chosen one hundred exceptional objects from the Museum’s immense storehouse of specimens and artifacts—one for each year of our history. Check back here frequently to learn more about this diverse selection of behind-the-scenes curiosities—we will post the image and description of a new object every few days.

This description is from Dan, the museum’s curator of vertebrate zoology. He’s chosen a selection of objects that represent the most fascinating animals in the Museum’s collections, that we’ll be sharing here – and at 100.hmns.org- throughout the year.

The Dooley-Selden team led the first HMNS mounted expedition. In 1959, HMNS’ first Curator, Tom Dooley, was invited by Board Member Selden to collect specimens in the northern (Saharan) region of what was then Tanganyika (today Tanzania). The objective of the expedition was to collect specimens for exhibition at the museum. Nearly 100 specimens were collected, including a vast array of birds and ungulates (hoofed mammals), as well as a few carnivores and small mammals.

CHI_5405 resizeThis is one of a handful of Okapis (Okapia johnstoni) exhibited in a U.S. museum, and this particular specimen was donated by Chicago’s Brookfield Zoo.

The Congo Basin of Africa, which is the region Okapis are restricted to, is characterized by civil unrest and political instability, with rural people often unsure of what tomorrow will bring, let alone where their next meal will come from.  Consequently, wildlife of this region is highly threatened due to the bush meat trade, where wildlife is harvested unsustainably for European markets in order to make ends meet in an otherwise destitute economy.

Sharks are our friends!

When I was in fifth grade, I was all about sharks. My favorite book was about sharks; my father even woke me up on school nights to see the shark specials on TV. I didn’t realize then that my 10 year old peers did not share my love or fascination with these creatures of the deep. Now, however, I do see that people are unnecessarily afraid of sharks. I think it’s about time a few more people disregard the scary myths, and start learning how awesomely-cool they are!

*Sharks have been around since before the dinosaurs, more that 300 million years. They have changed little over time and are sometimes called living fossils.

*Sharks’ skin was used to polish wood before the invention of sandpaper. It is covered in teeth-like projections called denticles. Most sharks’ dermal denticles point uniformly towards their tail. The exception to this is the Basking shark, whose denticles point every which-way! Some Norwegians line the bottoms of their boots with Basking shark skin to help with traction on slippery, wet surfaces.

*The extinct Megalodonwas the largest shark to ever exist. It had teeth the size of a human hand. As a sidebar here, I was out at a conference touting the wonders of the Museum and showing off some impressive fossils, one of which being a shark’s tooth – not a megalodon, but still impressive. I was holding it for a teacher to see its serrated edge and it actually cut open my finger. Who else can say they were bitten by a million’s-of-years-old shark?!

*Great white sharks live about 25 years. They do not start reproducing until they are around 20, and only have around 2 litters of 6-7 pups in their lifetime. Some scientists believe there are only around 10,000 in the world. As an apex predator, they are at the tops of the food chain and are needed to maintain balance in their respective ecosystems.

*Some sharks only grow to be 8 inches long!

*The largest shark today is the Whale Shark, which can grow up to 50 or 60 feet long. Don’t worry, though, they’re filter feeders that eat plankton!

*More than 375 species of shark have been discovered so far; less than a dozen of these are dangerous to humans. Also, 90% of all shark attacks, of which there are around 100 per year, end in the victim’s survival. This is because humans are not sharks intended prey. They take a taste – the sharks’ equivalent of sampling the menu - and spit out what turned out not to be a fish or a seal.

As you can see, sharks are not the vicious predators driven by blood lust that popular culture has made them out to be. Just respect them, and try not to dress up like a seal when you go swimming off the coast of South Africa. (Just kidding.) Have no fear of our finned friends!

egyptian-goose-gosling-mount-resizeThis is the oldest mount in the Vertebrate Zoology Collection that is currently on display.  It was part of the large Westheimer donation, purchased from H. P. Attwater in the early 1920’s.  The specimen is currently featured in Phase II of the Frensley-Graham Hall of African Wildlife

Phase II depicts many of the species in family or social groups, including mother-offspring associations such as the Egyptian Geese (Alopochen aegyptiacus) on display.
