The design on the reverse of this coin features a Blue Petrel diving into the Antarctic Ocean in order to catch fish. In the surround you can see two more Blue Petrels ready to join the feast! This coin is issued on behalf of the British Antarctic Territory. The Blue Petrel (Halobaena caerulea) is a small seabird that inhabits southern oceans. They reach about 200 grams in weight and a length of 30 cm. They have a white underside and face with a blueish grey topside. The Blue Petrel has an extraordinary ability to produce foul smelling oil which they store in a special section of their stomach called the Proventriculus; they then eat this oil to feed themselves during long flights! Titanium reacts differently with every strike, so each Titanium Blue Petrel coin is technically different and varies slightly in color. There is also a lined effect that is present on the coins which is unique to this metal. The obverse features the Pobjoy exclusive effigy design of HM Queen Elizabeth II in exceptional detail.
