Channeled apple snail (Pomacea canaliculata)

Keong mas or channeled apple snail (Pomacea canaliculata) is a species of animal in the Ampullariidae, freshwater snails, large, round shells with brown or black or yellow or albino colors and highly variable band patterns.

P. canaliculata has a shell with a length of up to 15 cm, the threads have four levels with a pointed tip. Most are brown or yellow and some are black or white.

Keong mas live in clear freshwater habitats including rivers, ponds, swamps and rice fields. The eggs are pink and are laid on grass and other vegetation that grows along bodies of water.

The channeled apple snail is highly polyphagous and feeds on floating and sinking plants, detrital, and animal matter. Diets may vary according to age with younger and smaller individuals eating algae and detritus, while older individuals turning to taller plants.

Six new species forming the Sumbana species group in genus Nemophora Hoffmannsegg 1798 from Indonesia

NEWS - Sumbawa longhorn ( Nemophora sumbana Kozlov, sp. nov.), Timor longhorn ( Nemophora timorella Kozlov, sp. nov.), shining shade longhorn ( Nemophora umbronitidella Kozlov, sp. nov.), Wegner longhorn ( Nemophora wegneri Kozlov, sp. nov.), long brush longhorn ( Nemophora longipeniculella Kozlov, sp. nov.), and short brush longhorn ( Nemophora brevipeniculella Kozlov, sp. nov.) from the Lesser Sunda Islands in Indonesia. The Lesser Sunda Islands consist of two parallel, linear oceanic island chains, including Bali, Lombok, Sumbawa, Flores, Sumba, Sawu, Timor, Alor, and Tanimbar. The oldest of these islands have been continuously occurring for 10–12 million years. This long period of isolation has allowed significant in situ diversification, making the Lesser Sundas home to many endemic species. This island chain may act as a two-way filter for organisms migrating between the world's two great biogeographic regions, Asia and Australia-Papua. The recognition of a striking cli...

Banded dragonfish (Akarotaxis gouldae) diverged from Akarotaxis nudiceps 780,000 years ago

NEWS - A new species of dragonfish, Akarotaxis gouldae or banded dragonfish, off the western Antarctic Peninsula by researchers at the Virginia Institute of Marine Science at Gloucester Point, the University of Oregon at Eugene, and the University of Illinois at Urbana-Champaign, highlights the unknown biodiversity and fragile ecosystems of the Antarctic. A. gouldae was named in honor of the Antarctic Research and Supply Vessel (ARSV) Laurence M. Gould and crew. The larval specimen was collected while trawling for zooplankton and was initially thought to be the closely related Akarotaxis nudiceps hundreds of thousands of years ago. DNA comparisons with A. nudiceps specimens held in collections at the Virginia Institute of Marine Science, Yale University, and the Muséum national d’Histoire naturelle in Paris showed significant variation in mitochondrial genes that suggested the larval sample was a distinct species. Andrew Corso of the Virginia Institute of Marine Science and colle...

Bush sorrel (Hibiscus surattensis)

Bush sorrel ( Hibiscus surattensis ) is a plant species in Malvaceae, annual shrub, crawling on the surface or climbing, up to 3 meters long, thorny stems, green leaves, yellow trumpet flowers, grows wild in forests and canal edges, widely used for vegetables and treatment.
