Pitcairn Islands – White-spotted Jellyfish – $2 – 2010 – Proof Silver Crown -COA – Phyllorhiza punctata is a species of jellyfish, also known as the Australian spotted jellyfish or the White-spotted jellyfish. It is native to the southwestern Pacific, where it feeds primarily on various snail species. Phyllorhiza punctata average 16 to 20 inches bell diameter. They have only a mild venom and are not considered a threat to humans. However, their ability to consume plankton and the eggs and larvae of important fish species is cause for concern. Each jellyfish can filter as much as 13,200 gallons of sea water per day. While doing that, it ingests the plankton that native species need. This Two Dollar legal tender proof silver crown was authorized by the Government of the Pitcairn Islands and the total mintage worldwide was limited to 1,000 coins. It comes with an individually numbered Certificate of Authenticity.
