Ocean Zones: Daylight Zone - 2016 Turquoise Titanium Coin

The oceanic zone is divided into three sections. The epipelagic zone, which is also known as the Daylight zone and receives enough sunlight to support photosynthesis; the mesopelagic zone, which is also known as the Twilight zone and only has a scarce amount of light; the bathypelagic, or Midnight zone which makes up 90% of the ocean and no light penetrates its boundaries.

The range of animals amongst the three zones is diverse and, especially in the lower zones, quite unusual. There are three coins in the series each representing a different zone and featuring the creatures that live in them.

• The design on this coin features the Daylight Zone which displays a dolphin breaking the surface of the water with a Cod Icefish, a Patagonian Toothfish and some Krill swimming below.

To emphasise the amount of light in each zone and to differentiate the three coins, each coin is being produced in a different shade of blue titanium.
