The beautiful first day cover of Alderney has sealed with the WWF stamps issued on November 2, 1993. The local FDC has post mark of WWF logo. The issue stamps are depicts 4 (four) species of sea life , Spiny Lobster (Palinurus elephas ), Plumose Anemone (Metridium senile), Seven-Armed Starfish (Lucida ciliaris), and Green Urchin ( Psammechinus milliaris).
Plumose Anemone, sea anemones found mostly in the cooler waters of the northern Pacific and Atlantic oceans. They are characterized by their numerous threadlike tentacles extending from atop a smooth cylindrical column, and can vary from a few centimeters in height up to one meter or more. In larger specimens, the oral disk becomes densely curved and frilly.
Seven-Armed Starfish or Luidia ciliaris is a species of starfish in the family Luidiidae that occurs on the seabed in the eastern Atlantic Ocean from Norway and the Faroe Islands southwards to Cape Verde and the Azores and in the Mediterranean Sea. Luidia ciliaris is an orangeish-brown colour and has seven long arms radiating from a small disk. This species is large but fragile starfish, growing to forty centimetres across, and easily losing its arms (which afterwards regenerate).
Green Urchin or Psammechinus miliaris is a species of sea urchin in the family Parechinidae. It is sometimes known as the green sea urchin or shore sea urchin. It is found in shallow areas of the eastern Atlantic Ocean and the North Sea.The green sea urchin prefers to eat seaweeds but will eat other organisms that float by or even catch small fish. The Psammechinus miliaris are eaten by a variety of predators, including sea stars, crabs, large fish, mammals, birds, and humans. It is found on rocky substratum in the intertidal and up to depths of 1,150 meters
Spiny Lobster have typically a slightly compressed carapace, lacking any lateral ridges. Their antennae lack a scaphocerite, the flattened exopod of the antenna. Spiny lobsters are found in almost all warm seas, including the Caribbean and the Mediterranean Sea,
