Mouse Opossum

Marmosa sp


Tiny brown and beige opossum with babies. The eyepatches sloping down towards the end of the nose are dark black.


Common in the lowland rain forests of Southeastern Ecuador. Can be found on the ground scrounging for insects or in the trees.


I can't get a handle on the difference between Marmosa lepida and Marmosa murina so just left it sp.

No... not snake food! I buy pinkie rats for my snake - granted you don't have that source. Glad you let the little guys go

Opossums were brought by for snake food. After the people left, I always took pictures and let them go again. Very cool.

Thanks Forestdragon. I was going to do that, but then thought if people see it is identified, they might not check it out. We have so many small opossums here and they are so similar. Thanks for the help.

Nice series! If you are unsure of the species but are confident with the genus you can put the genus as the scientific name (e.g. Marmosa sp.) and call it Mouse Opossum as the common name. Thank you for sharing all of your wonderful images and experiences!
