Today’s post will introduce two very strange aquatic creatures found at one of Canberra’s nature reserves — the first, one very odd looking duck, and the second, quite duck-like.
Australia’s musk duck looks half-fish, half duck. It must be the oddest looking duck I’ve ever come across. It is so named because it is very smelly, emitting a musky smell from scent glands on its rump. Musk ducks spend most of their time in the water. They even sleep on the water. They can fly, but launching from the water or ground is hard work, so they do so infrequently. When fleeing predators, they choose a watery escape rather than take to the wing.
Solitary birds, they will defend their territory from other musk ducks. Males exude machismo. They have a pendulous lobe on their neck which they puff out to impress the ladies. My youngest son was only three years old when he saw his first musk duck, but he vividly recalls being rushed by an amorous specimen intent on protecting his lady. The male’s protective attitude is, however, merely pretence. Once the lady musk duck is inseminated, the male dumps her and moves on. There is no mating for life or assistance with raising offspring. Still, I can’t help admire their self-confidence and grace in the water.
Is it a fish?
How is this for handsome?
I was fascinated with how the water beads on the feathers.
If you think the musk duck is strange, then the platypus is even stranger. The platypus is a monotreme, a mammal that lays eggs but suckles its young, excreting milk through the pores of its skin. Males are about 50cm in length, and females slightly smaller. Researchers have found that the platypus has 10 sex chromosomes, unlike other mammals which have two (XY), and it has genes in common with birds and reptiles (read all about it on Wikipedia. It is totally fascinating). And what a funny looking creature it is. It has a bill like a duck, a tail like a beaver and webbed feet like an otter. Male platypus are also one of the few venomous mammals. They have a spur on their back leg that can inject poison. Like the musk duck, platypus are polygamous and the male may have several ladies across his range. Males play no role in raising young.
The platypus needs to eat about 20% of its body weight each day to survive, so it spends about 12 hours each day in the water feeding off the river bed and the bottom of dams/lakes. Maintaining the health of waterways is vitally important. (Australians will know that recent low-levels of oxygen due to temperature fluctuations and low water flows, killed off massive numbers of fish and crustaceans at Menindee. Be wary when vested interests lobby for extracting “under-utilised” water from elsewhere and piping it inland.)
The platypus swims completely blind, closing its rather inefficient eyes in the water, and uses its bill to sense food through tiny electro-receptors. Platypus eyes contain double-cones, which most mammals do not have. Double-coned eyes are found more commonly in fish, reptiles and birds. So you get the idea; the platypus is truly remarkable.
Fish, bird or reptile? No, just a very unusual mammal.
Eyes closed.
Eyes open.
Neither of these critters spend long on the water’s surface. They can travel a considerable distance under water, so getting a good photo before they dive again* involves more luck than good planning. My thanks goes to my true love for taking the platypus photos. I could manage only a few weeds. I did, however, have much better luck at photographing the musk duck. Perhaps he was trying to impress me?
Kind Regards
Tracy

Their toxin load is greatest in the breeding season, so they must use their spur to fight off other males.

I loved this post! I had never heard of the musk duck, and did not know much about the platypus, other than the mammal/egg/milk facts. I agree with you that it is totally fascinating that they have common genes with birds and reptiles, and the 10-sex-chromosome fact is just mind blowing. Thank you for all the information and the great photos, Tracy!

You’re welcome, Irene. I didn’t know much about the platypus either. I’ve not really kept up on platypus science since I was a kid. What the scientists are revealing is truly astonishing.

A beautiful post Tracy, I’d never seen a musk duck before and there’s something very prehistoric about their appearance. What a treat to see these creatures with your own eyes! Thank you so much for sharing 🙂💖 xxx

You’re welcome, Xenia. I was completely transfixed by the musk duck. The platypus was often just a dark shape in the water to me, popping up momentarily before diving again.

So if you’re a visitor and visit this reserve, what would the chances be that you’d actually SEE a platypus?

A very good chance, Liz. We would have not been able to see details like the eyes without the camera though. We find many people are not patient enough, and in galloping along, they miss a lot.

So enjoyed getting to know the musk duck and platypus in Canberra, Tracy. Wonderful shots too, great timing capturing them dipping their heads into the water. That’s amazing to hear the musk duck can sleep on water. Sound like it’s a bird of many talents along and that might explain their self-confidence. Interesting to read the platypus swims completely blind. That is amazing it swims and still has a sense of direction. I’ve seen platypuses here in Melbourne, but not sure if I’ve seen musk ducks around here 🙂

Hello Mabel, thanks very much for visiting and your kind comments. The musk duck is listed as vulnerable in Victoria so I imagine it is quite rare. Best wishes. Tracy.
