Bassariscus astutus

We have a taxidermied ringtail (Bassariscus astutus) in the Visitor Center at the Park. I’d sure love to see a live one.

Ringtails are members of the raccoon family. They are found in many areas of California, but they are rarely seen. They have large eyes and upright ears, which assist them to navigate and hunt by night. Their long tail helps them to balance while climbing in trees and rocky places.
Ringtails eat rodents, birds, rabbits, reptiles, frogs, fruit and berries. They prefer a solitary existence though they may occasionally share a den. They are preyed upon by foxes, coyotes, raccoons, bobcats, hawks, and owls.

Smaller than a house cat, its body measures 30–42 cm (12–16.5 in) and its tail averages 31–44 cm (12–17 in) from its base. Ringtails are said to be easily tamed, and can make an affectionate pet and effective mouser. They are the state mammal of Arizona.

Chlaenius aestivus

We had fun drawing a ground beetle with Trisha this past week, especially as the specimen had mysterious additional mouthparts that our entomologist had never seen before. I didn’t do a great job depicting the metallic red/green head and pronotum. I’d like to get myself some metallic watercolours for times like these.

Lybia edmondsoni

OK, this is the cutest thing I’ve learned about all week. Tiny, pugnacious pom-pom crabs have very thin shells, and so they use anemones to defend themselves, waving them around vigorously like boxing gloves. I wondered if they put them down to eat, but it seems that the anemones collect food as they are being swished through the water, and the crabs just nibble it off them. Kind of like licking your swiffer I suppose (ugh, gross).

The crab/anemone relationship is symbiotic, though it seems that the crab gets the better end of the deal. If one of its pom poms gets lost, the crab will just tear the other one in half. Each half will grow into a complete organism. Isn’t nature amazing?
