Thai and Malaysian post jointly issued a set of stamps featuring Marine Creatures to create awareness among the people for conserving marine life and resources as they are rapidly declining around the world.
Marine creatures are very useful as they help to clean the ocean and provide oxygen. They are useful from the medicinal point of view also.The stamp issued are in conjunction with this year’s World Oceans Day celebration.
The stamps features the white spotted jellyfish (Phyllorhiza punctate) and sea slug or nudibranch (Hypselodoris bullockii) chosen by Malaysia, and the coral guard crab (Trapezia areolata) and harlequin shrimp (Hymenocera picta) selected by Thailand.
Phyllorhiza punctata is a species of jellyfish, also known as the floating bell, Australian spotted jellyfish or the white-spotted jellyfish. It is native to the warm, tropical waters of the western Pacific Ocean, from Oceania through East Asia, but has been introduced widely elsewhere. It feeds primarily on zooplankton. P. punctata average 45–50 centimetres (18–20 in).
White-spotted jellies have very mild venom and do not pose a threat to human beings. In fact, these jellies do not generally use their venom to capture food at all. Instead, white-spotted jellies are filter feeders, like oysters or sponges. They can filter more than 50 cubic meters (1,766 cubic feet) of seawater every day!
Hypselodoris bullockii is a species of colorful sea slug or dorid nudibranch, a marine gastropod mollusk in the family Chromodorididae. Hypselodoris bullockii is quite variable in color.
Coral reefs face a plethora of threats, from ocean acidification to coastal development to climate change. But at least when it comes to direct assaults, some corals have well-armed defenders: coral guard-crabs. Looking between the branches of Pocillopora stony coral of the Indo-Pacific and you may find tiny crabs from the genus Trapezia, the largest of which measure only a few centimeters.
These buff little crustaceans take up residence within pocilloporid corals—the ones that look a bit like cauliflower or loose brains. In exchange for shelter and nutrients, the crabs ferociously defend their hosts from hungry enemies, such as snails and crown-of-thorns sea stars.
Hymenocera picta, commonly known as the harlequin shrimp, is a species of saltwater shrimp found at coral reefs in the tropical Indian and Pacific oceans.
It is usually considered the only species in the genus Hymenocera,but some split it into two species: H. picta from the central and east Pacific where the spots are deep pinkish-purple with a yellow edge, and H. elegans from the Indian Ocean and west Pacific where the spots are more brownish and have a blue edge.
