Threshold Creatures - Between Land & Sea

I am beginning to feel that the Platypus is the Australian Otter - I adore both of these threshold animals that can survive just as well in the water as on land. The Celts had such reverence for animals who guarded the thresholds. Otter is an ancestral totem for me and I am only just discovering and learning more about the platypus.

Here is the platypus pool at the Southern Ash Wildlife Shelter - looks like heaven to me.
