Originally posted by mroeder75 I believe our opossums are ominverous. I have never seen one in a tree but their are photos galore of them climbing trees. When very frightened they play dead, or just can't move.
OK, they're omnivores, so they possibly have a similar niche to the Brushtail Possum. I'm familiar with the expression "playing possum" although ironically it's not a defence mechanism used by Australian possums.
I don't think there's anything in North America which is in quite the same niche as the Echidna (since the Echidna is an ant and termite specialist), but perhaps the Armadillo is close.

Originally posted by Bob Harris the feathers remind me of the quills of the porcupine Robb.
They are similar in that they're both made of the same material as fingernails, but while the Porcupine quills break off, Echidna spines don't. I once lifted an Echidna using a blanket for padding to move it off a highway, and no harm was done to the animal. When threatened, the Echidna will dig into the ground to protect its head and belly while exposing the spines.
