With its gaping mouth, needle-sharp teeth, and slightly startled expression, the black sea devil anglerfish seems tailor-made for the spotlight.
And in fact, one particular female got her close-up on November 17 when researchers got footage of this rare anglerfish—the first time this species has been filmed alive and in its natural habitat—off of central California
MSU scientists have made a number of improvements on the fish, including the ability to glide long distances, which is the most important change to date. The fish now has the ability to glide through the water practically indefinitely, using little to no energy, while gathering valuable data that can aid in the cleaning of our lakes and rivers.
Soares and her colleagues used high-speed cameras to film a group of nine male guppies from the island of Trinidad. Their research, published online April 16 in the journal PLOS ONE, suggests wild guppies use their curious jumping ability as a way to spread the species away from an original habitat, to a new place with fewer predators. In other words, jumping likely serves a crucial evolutionary function for guppies.
