The opossum gestation period is only 11-13 days.
When they are born, the babies are the size of a lima bean!
We've discovered a snail never before found in L.A.! A few weeks ago, I was wandering through the North Campus and happened upon a tiny gastropod snailing along the Living Wall! Most snails don't catch my attention as they are usually of the common garden variety, aka Brown Garden snails, Helix aspersa.

We have another new sighting for the North Campus. A California ground squirrel has been spotted using the opossum den located underneath one of our Museum sheds. So far it seems that both the opossums and the squirrels are sharing the space!
This is what Jim Dines, our Mammalogy Collections Manager, has to say about them:

On Sunday, February 26, Museum Educator Anna Holden, and myself took some families out to the North Campus to collect spiders! The spiders were collected so they can be identified and preserved as part of our ongoing L.A. Spider Survey. They will also be added to our ever-growing North Campus species list.
All told, we collected 17 spiders (not bad for a newly planted habitat) many of which were very small and non-descript – think tiny brown specks almost indistinguishable from a piece of dirt (did I mention these children have amazing eyesight?). However, there was one...
