The jellyfish is translucent, usually about 25–40 cm (10–16 in) in diameter, and can be recognized by its four horseshoe-shaped gonads, easily seen through the top of the bell. It feeds by collecting medusae, plankton, and mollusks with its tentacles, and bringing them into its body for digestion. It is capable of only limited motion, and drifts with the current, even when swimming
Medium sized lemur in the Indriidae family found in a variety of habitats and are famous for their "dancing" across open spaces but do also makes huge leaps between trees. This lemur has long, thick, soft hair that is mostly white with a dark brown crown that extends down the back of the neck. It has a dark grey or black face which contrasts with its large, bright, yellow eyes. The fur is thinner on its chest, belly and underarms allowing the grey skin to show through, and male Verreaux's sifakas may also have a faint reddish-brown area on the chest, caused by a gland at the base of the throat.Like other sifakas, its arms are short, and somewhat limited in their movements; however, their hind limbs are large and strong, providing the power for them to leap from tree to tree. The name of the sifaka comes from the sharp, piercing call that this primate makes, which sounds like shi-fahk. This species is currently listed as vulnerable on the IUCN Redlist with habitat destruction being a major threat.
For the developers at New York start-up Networked Organisms, smartphones are the butterfly nets of the 21st Century. Their tool, Project Noah, lets people upload photos of plants and wildlife around them, creating a map of the natural world and contributing to scientific research in the process.
Bespectacled scientists of yore would carry around hefty field guides, made up of hundreds of pages of text and photos. But these days, smartphone owners have a lighter option: an app called Project Noah, which aims to help people identify plants and animals as well as collect data from "citizen scientists" about where certain species are located.
Project Noah enables us to be part of a more focused online community where we can learn more about wildlife around us and contribute to scientific research. It pulls participants into deeper, more meaningful engagement by enabling people to go on “missions” to collectively map changes based on sightings.
A modern invention that may also hold the key to saving species in the future. Project Noah is a global study that encourages nature lovers to document the wildlife they encounter, using a purpose built phone app and web community. In addition to the virtual "collection" of species, Project Noah encourages citizen science by linking up with existing surveys including the International Spider Survey and the Global Coral Reef Monitoring Network.
