Watching Wild on Nat Geo yesterday....

and there were a series of episodes about marine life in Australia. There were some really odd ones like the Ras fish that looks like some prehistoric and like it had another fish on top of it with a big hump on it as well, Then there was the Leafy Sea Dragon that was beautiful and would swim in among the sea weed as it's camouflage. The Horse Shoe Crab sure is a homely cuss until that prehistoric shell is taken off. The stone fish is sure a good camouflage. It looks just like a stone and then rustles down in the sand and you wouldn't know it was a fish. But, the one that really struck me was the narwhal which is called the Unicorn of the Artic Sea. Its a whate of about medium size that has this large tusk that is actually a canine tooth. It is actually an elongated upper left canine and has soft enamel on the outside with a lot of nerve endings. This is used as a sensor to detect water pressure, temperature and salinity. It might even detect barometric pressure when it's above the water's surface. I found this fascinating. Had never heard of it before.

I did not know about unicorn fish till I read your post. Its antenna looks awesome and it is interesting to know that these antenna works as sensor and help unicorn fish to detect nature of water. Nature is really great, if we explore we get to know about many animals, which are rare to find or seen in general.

I love to watch and learn too Celtic. Those nature shows are incredible. I certainly wish they had more of them on. No I had never heard of the Unicorn of the Arctic Sea, but is sounds such a regal name indeed. It certainly looks a good tool for the creature in order to gage different elements that will help them survive better.

Yes, and to find out it is a tooth was very interesting. They have these on every week and then you can find marathons like I did. I always venture ahead to see what I will watch and I can schedule it in my DVR and check each day to see what I want to watch and what I will let the DVR tape for another time.
