#DYK ? The bull shark is one of the few sharks able to survive in freshwater & saltwater. Some scientists think this ability gives the species an edge—because it allows moms to give birth in freshwater, where their newborns generally face fewer threats #SharkWeek  📸: Albert Kok

Elephants shape the landscapes they inhabit, dispersing seeds, making paths for other animals, & creating clearings for trees & other plants to regenerate. It’s important to protect elephants & their habitats to ensure their future for generations to come. #WorldElephantDay 🐘

Meet the Cattle Egret! It's named for its association with grazing animals: It tracks large mammals to find its own prey, like insects or frogs, which are disturbed by the foraging. Depending on its locale, it hangs out around other grazers like rhinos & sheep! [📸: Fstern]

#DYK ? Sharks have cartilaginous skeletons coated with hard calcium minerals. It's just one of many special traits that give sharks an edge in the ocean. Cartilage has several advantages over true bone: it’s tougher, lighter, and more flexible #SharkWeek  🦈

The external, private event at which the current President of Brazil is to be honored was booked at the Museum before the honoree was secured. We are deeply concerned, and we are exploring our options.

Next time you eat guacamole, thank a giant ground sloth: the Lestodon! These 15-ft animals ate avocado whole, traveled, and then pooped, depositing the pits in new places. Most mammals couldn't handle large seeds, so it was up to megafauna to disperse (and fertilize!) avocados.

A wombat’s main defense is a tough backside: its rump is mostly cartilage, resistant to bites. A group of #wombats  is called a wisdom.

It's #ManateeAppreciationDay ! Did you know manatees are natural lawn mowers that help maintain healthy marine ecosystems by keeping aquatic vegetation in check? Sometimes referred to as “sea cows,” they are actually more closely related to elephants. #Respect  the manatee!

Jackal food is a parasitic plant native to Africa that siphons off nutrients from other plants' roots. Its flowers surface after heavy rainfall & emit a carrion-like stench to attract pollinators. Its fruit is similar to a potato & attracts animals like jackals. [📸: E. Black]

Behold the rainbow eucalyptus! What gives it such a spectrum of color? Bark starts out in shades of green, but changes to a range of purple, red, & orange as it peels and ages. Variety of color may help the tree absorb a wider range of light to aid in photosynthesis.
