The cactus wren is about eight inches (21 cm) long. It has a white belly with brown spots, and speckled brown, black and white feathers on its back, wings and head. It has black feathers on its throat and a long stripe of white feathers that looks like eyebrows. It has long legs and a long pointed bill.
The Northern Quoll is listed as Endangered on the IUCN redlist. The Northern Quoll is a small marsupial - the smallest of the four species of Quolls. Females have eight teats in a pouch, but apparently give birth to more than eight young which must wriggle their way to the pouch and compete for a teat to survive - Wiki A remarkable feature of this species is that the males show complete die-off after mating, leaving the females to raise the young alone. - Wiki The Northern Quoll’s short life-span and annual male ‘die-off’ makes populations vulnerable to extinction from high-impact threats such as those posed by the initial invasion of large numbers of cane toads into an area. Nevertheless, some populations – such as that on Brooklyn - have persisted for decades after invasion by cane toads. It is possible that surviving quolls may have learnt not to eat toads. - AWC (http://www.australianwildlife.org/wildli...) Cane toads have already reached Gibb River Station which is to the east of Bell Gorge where this little one was spotted during the day.
Crinoids are marine animals that make up the class Crinoidea of the echinoderms (phylum Echinodermata). Crinoidea comes from the Greek word krinon, "a lily", and eidos, "form". They live both in shallow water and in depths as great as 6,000 metres (20,000 ft). Sea lilies refer to the crinoids which, in their adult form, are attached to the sea bottom by a stalk. Feather stars or comatulids refer to the unstalked forms. Crinoids are characterised by a mouth on the top surface that is surrounded by feeding arms. They have a U-shaped gut, and their anus is located next to the mouth. Although the basic echinoderm pattern of fivefold symmetry can be recognised, most crinoids have many more than five arms. Crinoids usually have a stem used to attach themselves to a substrate, but many live attached only as juveniles and become free-swimming as adults. There are only about 600 extant crinoid species, but they were much more abundant and diverse in the past. Some thick limestone beds dating to the mid- to late-Paleozoic are almost entirely made up of disarticulated crinoid fragments.
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.
