I don't think I'd ever seen the Christmas Island crab babies before. I had no idea how adorable they are!

There are so many that they form the base of a lot of food webs, including filter-feeding whale sharks who swallow them by the thousands.

Those that survive a few months will return to forage in the forests until they're about 3 yrs old & reach sexual maturity, ready to join Crab Spring Break.

Every year around Thanksgiving, I see tons of grad students post heartbreaking messages on social media about how their loved ones don’t understand or support their decision to study what seems like something pointless or silly.

Perhaps my American Scientist essay can help!

“Why Are We Funding This?”
Long-standing myths about “silly science” have contributed to the reckless slashing of government-supported research.
