Crab: armed and dangerous

Don’t mess with this Gangster Crab: It’s time these crustaceans fought back against the cruel process of boiling them alive. But what are those kitten noises?

The Sluggard

’Tis the voice of the Sluggard: I heard him complain, ‘You have waked me too soon! I must slumber again!’ —Isaac Watts (1715) h/t: Matthew Cobb  

Friday moggie: Simon’s Cat gets scientific

An old favorite, Simon’s Cat (website here), has added some Science to the cartoons, combining the usual amusing animations (in this case, one called “Let me in”) with an expert’s explanation of cat behavior (the expert here is Nicky Trevorrow). Apparently “Simon’s Cat Logic” will be a continuing series. Note that throughout this video, Simon […]

“Frog saves fishes” life? Not really

A reader sent me this recently-published YouTube video titled, “Frog saves fishes life.” (It’s in Spanish, but you can see what’s going on.) The reader asked a reasonable question: why would a frog do this for fish, since they’re unrelated, unless it wanted to eat the fish later? Well, as you can see, they’re not […]

Snowy owl protects her young

This new clip from the BBC show Super Powered Owls shows a snowy owl, Bubo scandiacus, defending its young against hungry skuas and wolves. Because these owls breed north of the Arctic Circle, they don’t nest in trees: there aren’t any up there. To get a good view of the surroundings, though, they nest on top […]

Let sleeping tigers lie!

This video of one tiger waking up another, with a reaction by foreign visitors, was taken at the Dublin Zoo and posted on YouTube April 9. It already has nearly a million views. Listen to those roars!

The report, taken from a paper by Jesús Peneda et al. in PeerJ (free link) was based on observations from a […]

Fathered by the mailman? Well, not the mailman—it was the PM’s private secretary

by Greg Mayer A lot of work in behavioral and evolutionary biology concerns the evolution of mating systems—polyandry, polygyny, monogamy, promiscuity, and the like—and elucidating the factors that lead to the evolution of one or another. Mating systems can be variable within a species, and human societies exhibit a range of mating systems, with monogamy […]

Altruism or accident? You be the judge

A tw**t called to my attention by Matthew Cobb: If the turtles are related, it might even represent kin selection at work.

A new mutualism: mongooses clean warthogs

How could you resist a headline like this? (Click on it to go to the Inkfish site.) And even better, Preston calls attention to an article in this newsletter (free download from DropBox; I love these specialized newsletters):   Which contains this tersely but accurately titled article: And, to save you the trouble, here’s that […]
