This symbiotic anemones prawn has a transparent body with purple spots on the carapace. The V-shaped patch is quite characteristic of the genre Periclimenes. The legs are thin, long and white with bright blue stripes. Has two pairs of tongs, the second pair is greater than the first.
Adults have five longitudinal ridges on a whole body, a low caudal fin over almost half the animal length, and a pattern of dark spots on a pale background. Young zebra sharks under 50–90 cm have a completely different pattern, consisting of light vertical stripes on a brown background, and lack the ridges. They grow to the lenght about 2.5 m
Found this one in shallow water at 2-3 meters deep. It was half buried in the sand. This is normal behavior of this species. It is active in the night. When we approached it acted in typical defense behavior. A ray thretened on the tail will propel itself upward into a loop; if it has not escaped after the maneuver, the ray will curl into a ring with the belly facing outward, so as to present the area of its body with the highest electric field gradient towards the threat; these behaviors are accompanied by short, strong electric shocks up to 90 volts.
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.
