Lack of shell and have eight arms. They are marine and carnivorous animals.
The eight arms of the octopus equipped with sticky suckers and converge on the body of the animal; at their point of convergence present oral peak provided with a horn. Eyes in the head, highly developed brains and three hearts, two pump blood to both gills and the third to the body are housed. In the rest of the mantle organs are located, as the ink they use to escape predators; also have a siphon, which unlike the squid, can change direction with which ejects a large amount of water, thus promoting a high speed.
Each of their arms is connected with a small brain that depends on principal, which he uses to control his arms.
Carecen de concha y poseen ocho brazos. Son animales marinos y carnívoros. Los ocho brazos de los pulpos cuentan con ventosas pegajosas y convergen en el cuerpo del animal; en su punto de convergencia presentan la boca provista de un pico córneo. En la cabeza se alojan los ojos, muy desarrollados, el cerebro y tres corazones, dos de ellos bombean sangre a las dos branquias y el tercero al resto del cuerpo. En el manto se ubican el resto de vísceras, como el depósito de tinta que emplean para escapar de sus depredadores; también cuentan con un sifón, el cual a diferencia de los calamares, puede cambiar de dirección, con el que expulsa una gran cantidad de agua, impulsándose así a gran velocidad. Cada uno de sus brazos se conecta con un cerebro pequeño que depende del principal, los cuales usa para controlar sus brazos.
The painted wood turtle or ornate wood turtle (Rhinoclemmys pulcherrima) is a turtle species of the genus Rhinoclemmys in the family Geoemydidae. It is found in Mexico from Sonora southwards, and Central America down to Costa Rica. There are four recognized subspecies. It is a terrestrial lowland species, primarily an inhabitant of scrub lands and moist woodlands, but also occurs in gallery forest close to streams.
Rhinoclemmys pulcherrima is an attractive species with thin red lines on the face and extensive areas of red and black vermiculations on the limbs, thighs, and tail as well as on the ventral parts of the marginal scutes and near the midline of the plastron. It has a small head with finely serrated jaw edges. It is omnivorous, feeding on wildflowers, grasses, fruit, insects, worms, and fish. Because it is so attractive, it is often exploited for the pet trade. Unfortunately this species seldom does well in captivity and usually dies within the first year. In Mexico is currently under special protection (NOM 59).
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.
