Located in one of the country’s poorest economic regions but among the richest in biodiversity, 2,000 species of flowering plants and nearly 300 species of frogs call the mountain’s steep rainforest terrain home. Found! First Known Predator To Lure Prey By Mimicking Flowers. The orchid mantis, which resembles a flower, takes on this appearance in order to lure in prey, researchers say.
In fact, orchid mantises are even better at drawing in insects than some actual blossoms; they not only look like flowers, but they also beat the petally beauties at their own game, scientists added. Nature presents many examples of organisms evolving to mimic other creatures. Baffling Butterfly-Shaped Cloud Turns Out To Be... A Huge Swarm Of Actual Butterflies. Meteorologists in St.
Louis were baffled last week when radar images showed a strange butterfly-shaped cloud passing overhead on its way south. The cloud was shifting its shape dramatically on what otherwise was a “completely clear day,” Laura Kanofsky, a National Weather Service (NWS) meteorologist, told the Washington Post.
Colossal Squid Tests Could Reveal 'Kraken' Clues. Scientists have defrosted a colossal squid in a bid to unlock the mysteries around this rarely seen monster of the deep.
One of the ocean's most elusive species, a forklift truck had to be used to carry the 350kg (770lb) creature, measuring the length of a minibus, to the examination tank. It was hauled up by fishermen from a mile below the surface of Antarctica's remote Ross Sea, and had been frozen for eight months until experts in New Zealand got the opportunity to thaw out the animal and inspect it on Tuesday. The squid is a female, and its eight arms are each well over a metre (3.3ft) long.
It is estimated its two tentacles would have been about double that length, if they had not been damaged. Kat Bolstad, a squid scientist from the Auckland University of Technology who is leading the team examining the creature, described it as "very big, very beautiful". How mosquitoes are drawn to human skin and breath. Female mosquitoes, which can transmit deadly diseases like malaria, dengue fever, West Nile virus and filariasis, are attracted to us by smelling the carbon dioxide we exhale, being capable of tracking us down even from a distance.

Mystery Solved: How Archerfish Shoot Water at Prey With Stunning Precision. Conoce la sorprendente habilidad de camuflaje de los pulpos - Ojo Curioso. Pocas especies marinas resultan tan intrigantes como el pulpo.
Este molusco carnívoro habita en las profundidades del océano y es conocido por su extrema timidez, lo que le hace esconderse entre las grietas durante el día y salir a cazar por la noche. Una mutación natural da a la mosca de la fruta resistencia a compuestos tóxicos. La diversidad genética presente en las poblaciones naturales de moscas de la fruta les permite adaptarse a la presencia de compuestos tóxicos ambientales. / Roberto Torres.
Showing image 1 of 1 Los xenobióticos son compuestos químicos ajenos al organismo, naturales o artificiales como, por ejemplo, insecticidas y otros contaminantes ambientales, que si se acumulan pueden ser tóxicos. Un estudio realizado en la mosca de la fruta Drosophila melanogaster es uno de los primeros en relacionar una mutación natural con un cambio adaptativo al ambiente. El trabajo, liderado por Josefa González, investigadora Ramón y Cajal del Consejo Superior de Investigaciones Científicas (CSIC) en el Instituto de Biología Evolutiva (CSIC-UPF), se publica en la revista PLoS Genetics.
Las moscas que presentan la mutación son resistentes al insecticida carbofurano La mutación descubierta es una inserción en el genoma de un elemento móvil o transposón. Albino dolphin spotted in the Mediterranean could be one of just 20 in the world, say researchers. Marine researchers spotted the incredibly rare dolphin off the coast of ItalyThe mammal, thought to be a male, is good health according to experts There are only believed to be 20 albino dolphins in the wildBottlenose dolphins are normally grey in colour unless there is a mutation By Darren Boyle for MailOnline Published: 19:22 GMT, 27 August 2014 | Updated: 09:47 GMT, 29 August 2014 Marine researchers in Croatia have revealed how they have found a previously unrecorded albino dolphin, one of only 20 in the world.
The rare mammal - named Albus by the research team - was found in the Mediterranean swimming between Croatia and Italy. Three Things You Didn’t Know About the Arachnids That Live on Your Face.

Wolves Cooperate With Each Other, Dogs Form Hierarchies. Hot in the City: Why These Urban Spiders Thrive. Perhaps even creepier than spiders are city spiders. New research has found the humped golden orb-weaving spider grows larger and produces more eight-legged babies in urban areas. This spider (Nephila plumipes) is indigenous to the Australian countryside, but it's also commonly found in and around urban areas, like the city of Sydney, in southeast Australia. And despite the fact that it's not their native landscape, these city-dwelling spiders are thriving, according to the study by researchers at the University of Sydney. In urban environments, orb-weaving spiders grow to be larger than their counterparts in the country, the study found.
These city spiders also have an increased ability to reproduce, something the researchers determined by weighing the female arachnids' ovaries. Jellyfish Sting Under The Microscope In Slow Motion.
