Incredible world-first footage shows shape-shifting cuttlefish

An amazing video has, for the first time, captured cuttlefish walking like  hermit crabs to sneak up on their prey.

The intelligent sea creatures, which are closely related to octopuses and squid, raise their front arms while bending their other tentacles to mimic a crab's head and legs.

The fish then move their legs independently while they glide along the floor so they appear to crawl, and certain parts of the body form dark spots.

Volcanic Crystals Give a New View of Magma

 Volcanologists are gaining a new understanding of what's going on inside the magma reservoir that lies below an active volcano and they're finding a colder, more solid place than previously thought, according to new research. It's a new view of how volcanoes work, and could eventually help volcanologists get a better idea of when a volcano poses the most risk, according to Science Daily.

Monkey see, Monkey Do, Depending on Age, Experience and Efficiency

Wild capuchin monkeys readily learn skills from each other -- but that social learning is driven home by the payoff of learning a useful new skill, and could inform whether and how animals can adapt to rapidly changing conditions.

"When animals learn, they can learn very quickly," said Brendan Barrett, a graduate student in animal behavior, who led the study. "What are the psychological mechanisms animals use to learn?"

Budgerigars can identify spoken sounds without prior exposure to human speech

No experience with human speech is necessary for budgerigars to perceive the difference between "d" and "t," according to a study .

The debate over speech perception is unresolved, with some evidence supporting a speech-specific mechanism and other evidence supporting a general auditory mechanism. The latter case holds that, in the absence of extensive experience with speech, there should be no difference between speech and nonspeech perception. To investigate this scenario, Flaherty and colleagues used budgerigars, vocal mimics that are similar to people in their ability to perceive consonant and vowel tokens. The researchers divided 25 budgerigars into groups before hatching, raising some in complete isolation from human speech and others with extensive exposure to human speech.

Cowbird moms choosy when selecting foster parents for their young

Brown-headed cowbirds are unconventional mothers. Rather than building nests and nurturing their chicks, they lay their eggs in the nests of other species, leaving their young ones to compete for resources with the foster parents' own hatchlings. Despite their reputation as uncaring, absentee moms, cowbird mothers are capable of making sophisticated choices among potential nests in order to give their offspring a better chance of thriving, a new study shows. According to Science daily

Brown-headed cowbirds are known to lay their eggs in the nests of more than 200 other bird species of varying sizes, and typically do so after the host bird has laid her own eggs.
