O. richmondia has never received an official IUCN classification (Collins & Morris, 1985), however Sands & Scott (1997) regarded it to satisfy the "vulnerable" category because of habitat loss across its former range.
The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
Ornithoptera is a genus of birdwing butterflies found in the northern portion of the Australasian realm, east of Weber's line; the Moluccas, New Guinea, the Solomon Islands, and northeastern Australia; except for Ornithoptera richmondia, which may be found in far northeastern New South Wales, Australia, therefore the southernmost distribution of birdwings.
Ornithoptera, or the genus of birdwing butterflies, usually reproduce sexually and are oviparous. [9] In butterflies sex is determined by a WW/WZ system , with a heterogametic female, reverse of that found in mammals and many other insects, which have a heterogametic male. [ 10 ]
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
The ocean is separated into layers with the surface layer (or sunlight zone) reaching down to 660 feet. Beyond the sunlight zone lives the Pacific Viperfish. This is known as the twilight zone ...
The birdwings genus Ornithoptera comprises some of the largest and most beautiful butterflies in the World. The genus is distributed over southern parts of Asia to Australia.
Open ocean habitats are found in the deep ocean beyond the edge of the continental shelf. Alternatively, marine habitats can be divided into pelagic and demersal zones . Pelagic habitats are found near the surface or in the open water column , away from the bottom of the ocean.
