Leopard Seal (豹海豹)
Australian Antarctic Territory (2001)
15th February, 2009. Casey Station
Leopard Seal is second large seal in Antarctic, just after Southern Elephant Seal (南象海豹). Back colour is dark grey but light greyed abdomen, however it named leopard as its neck with black spots. Killer Whale (虎鯨) is its only natural enemy, smallest marine life like krill to large animal penguin also can become its food.
This set of WWF stamp shown the Leopard Seals playing with Adelie Penguins (阿德利企鵝), actually those penguins look facing danger as sometimes Leopard Seal kills them. When seal wants to catch them, it will lay under the water and wait penguins jump into water.
The cover was sent from Casey Station of AAT, that means I collected two station's postmarks. The postmark features a couple of Australian Sea Lion (澳洲海獅), they look very cute. Also have one signet on the left-bottom of envelope illustrated Adelie Penguins lay on a wooden case, do you think these three penguins look like escape the dangerous ?
