Not surprised there's so much life below! I went to Antarctica earlier this year. I thought it would be a barren landscape and not much wildlife to see. I'm glad this wasn't the case.
It was more like being on a wildlife safari. I saw several different species of whale. Humpbacks very close to our zodiak. Seals everywhere and different species. At one point, one got right into my face and I could even smell its horrible fish breath as it breathed on me.
Several different species of penguins and birds. It was fantastic and full of wildlife.
I highly recommend going down there if you can. Such a pristine piece of the earth teeming with life.
