Compared to other colors found in nature, true blues are pretty rare—but the indigo milk cap has just that! Its color comes from a pigment within. You'd think that its blueness is a marker for toxicity, but it's edible & turns gray when cooked. [📸:A.Rockefeller, CC-BY-SA-3.0]

Did you know the plumed basilisk can “walk on water?” By creating small air pockets with its rear toes & moving at a quick pace, it can run across water without sinking! If it does sink, no fret—it’s a good swimmer & can stay underwater for ~30 min.[📸:H.Hillewaert, CC-BY-SA-4.0]

You might be familiar with the Greater Roadrunner's need for speed, but did you know that it also feeds on venomous prey? Pairs have been observed teaming up on a rattlesnake—while one distracts, the other slams the snake's head on the floor! [📸: Dominic Sherony]

Put your hands up for the spotted handfish! The fish’s name nods to the hand-like fins it uses to “crawl” across the seafloor. What’s more, the spotted pattern is unique to each individual. [📸: CSIRO, CC BY 3.0]

You’ve heard of the aardvark, but did you know there’s an aardwolf? It's in the same family as the hyena, but unlike its carnivorous relative, the aardwolf is insectivorous. It’s one of 18 mammal species that feed exclusively on termites. [📸: Derek Keats]

Meet the flower hat jellyfish. Unlike other jellyfish that drift in the open ocean, this one's semi-benthic & spends its time near the sea floor. The tentacles around its bell allow it to catch fish from many directions—& the fluorescent tips may help lure in prey.[📸:mark6mauno]

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 Suriname toad mother carries her young embedded in the skin of her back. After mating, the eggs sink gradually into the female's back, & a skin pad forms over the eggs. The froglets emerge over a period of days, thrusting their head & forelegs out first, then struggling free.

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.
