⁉️ WHAT IS IT WEDNESDAY ⁉️

Last week's mystery was quite a stumper - it appears to be an EEL SKULL, but determining which species is difficult: there are about 1000 species of eels worldwide, with well over 100 living in Mexican waters where this one was found (we don't know exactly where). Eels range in adult size from a few inches (we know it's not this one!) to over eight feet (also not this one!), and have quite a range of skull and jaw shapes, although many different species are also very similar-looking. From the biggest to the smallest, they all start out as tiny, clear, flat-shaped larva called leptocephali.

This one could be one of our favorites here at the ANSC, the American eel! The size of this skull is about the size of our own resident American eel Houdini, but is is broken on both sides and missing the lower jaw. We'll keep investigating, and you can visit Houdini in our Small Wonders building!

This week's mystery is on a new slide loaded onto our microscope in the Naturalist Workshop - so hint: it's really, really tiny! What is it?

⁉️ WHAT IS IT WEDNESDAY ⁉️

We're back! It's been a little while, but take a look back at our last mystery - a gooey, funky-looking jar of SEA CUCUMBERS! While obviously named for their lookalike fruit, these animals are related to starfish, sea urchins, and other ECHINODERMS. But unlike their relatives, sea cucumbers have evolved reduced skeletons (yes, starfish and sea urchins have skeletons!), so they have wobblier, blobbier bodies with only small (microscopic) calcified ossicles making up their bony parts.

They display an incredible amount of beautiful, colorful, otherworldly-looking forms, and are super important to the health of the world's oceans: they act as cleaners of their environments, feeding on waste, decaying carcasses, and other organic matter that needs to be broken down and recycled for healthy oceans. Thanks, sea cucumbers!

Summer crowds are here, and we've been getting lots of fun things from all over the world brought in to our Trade Counter, including today's treasure: what is it?

⁉️ WHAT IS IT WEDNESDAY ⁉️

We're back! Our last beautiful mystery crystal was a DUMORTIERITE QUARTZ! The rare blue dumortierite is a mineral made of aluminum, boron, and silicate elements, with some other minerals that give it different colors from blue to pink and violet. It forms often as inclusions within quartz, such as in our examples, where it gives a light blue tip to the crystals that really shines and "flashes" over a bright flashlight. Under a microscope, we can see that the blue dumortierite is actually fibrous, glassy little blue prisms inside the quartz. Beautiful!

Today we have something beautiful in a different way! What is it?
