True facts about the Sand Bubbler Crab

Reader Vampyricon called my attention to this video about a crab unknown to me: the sand bubbler crab. It eats sand, extracts the organic material, and then spits out the sand in a series of little balls. Moreover, as Wikipedia notes, In each burrow, the crab waits out the high tide in a bubble of […]

Readers’ wildlife photos

Today we have several photos of a rodential nature, and from two readers, whose comments are indented. As lagniappe, there’s a crustacean and a bird. The first batch comes from Gary Womble: Only whole grains for this little guy: I would not want to get between him/her and those nuggets: And finally, the kill! A […]

Giant isopods on the sea floor rip apart an alligator carcass!

Reader J. J. sent me a link to the fascinating video below along with the commentary below, which, along with the video, tells you all you need to know. I’ll add, though, that this euthanized gator was placed ten miles off the coast of Louisiana and 1.25 miles down on the sea bed. And I […]

Readers’ wildlife photos

I’m scheduled to go to Antarctica in the fall of next year, lecturing on evolution on two separate cruises to Patagonia, Antarctica, and the Falklands, so I was excited when reader Daniel Shoskes sent me some photos of a trip he took recently to Antarctica and Chile. I present his photos (bonus Darwiniana!), with Daniel’s […]

The remarkable sand bubbler crab

Should I have called this “You won’t believe this amazing crab?”. Or maybe “Samantha Bee throws shade on haters of bubbler crabs”? Regardless, you need to know about—and see—this remarkable animal. I knew nothing about it before I came upon this video, taken from BBC’s “Blue Planet” series. Sand bubbler crabs comprise a variety of […]

Readers’ wildlife photographs

This is the second installment (first here) of photos taken by Jeffrey Lewis on Bonaire. His notes are indented, and I repeat part of the introduction to the last batch. There will be one more installment: These were all taken on a family vacation to Bonaire, an island in the Caribbean just off the coast of […]

The mighty pinch of the coconut crab

The coconut crab, or “robber crab” (Birgus latro), is the largest terrestrial arthropod in the world, with individuals weighing up to four kg (about 9 pounds).  They have a wide range: But because of their size and the fact that they’re tasty, they’ve been largely driven extinct by humans on populated islands. Here’s how big they are: They […]

Readers’ wildlife photos

Reader Robert Lang made a trip to Costa Rica earlier this year, and sent some photos of arthropods. His captions are indented: We saw fewer arthropods (other than butterflies) than I expected in the various wet forest environments, but the ones we did see were quite spectacular. The Blue Land Crab (Cardisoma guanhumi) was shot […]
