Anny Scoones: A salute to marine mothers, from lobsters to octopus

What makes the she lobster so contemporary is that she goes looking for her mate by tapping and poking the tips of her claws into the male abode, and if she finds the lucky catch, she enters, whereupon the male taps his claws as a welcoming gesture (she hopes). This behaviour is known as “boxing.” It is thought the future husband actually taps her to get a sense of the hardness of her shell and when she may molt, because when she does, the matrimonial action occurs! She will then lie on her back while the male performs his magnificent gesture.

Supermoms and Slacker Moms of the National Parks

camera icon Supermom: Grizzly Bear Grizzlies and brown bears are fierce defenders of their cubs, chasing away predators including male grizzlies, who are known to kill babies in order to mate with mama (not smooth, fellas). Their protective nature stems from having the lowest reproduction rate among all mammals in North America; grizzlies typically birth two or three cubs every five years. Brown bears, many of which are a heftier version of the same species, can be found in many of Alaska’s national parks, but in the Lower 48, grizzly bears are currently only found in Glacier, Grand Teton and Yellowstone, with a handful or fewer remaining in North Cascades.
