If you're interested in fish who are scary-looking, poisonous and chock-full of elaborate defense mechanisms, look no further than the stonefish, a genus of fish that populate coastal waters of the Indo-Pacific region.As if their deadly venom and spiny exteriors weren't enough, scientists at the University of Kansas have found that stonefish also have a hidden switchblade on their face that they can flick out whenever they feel like they're in danger.Scientists call the bony, blade-like protrusion a "lachrymal saber," because it is located on a bone under the fish's eyes. Also, "lachrymal saber" is just a really metal-sounding name.William Leo Smith, associate curator and associate professor of ecology & evolutionary biology at KU, first started to understand how the lachrymal saber worked 15 years ago, when he was dissecting a stonefish he kept as a pet.This is a game-changerHe tells CNN the mechanism isn't just a cool new discovery (although it's that, too). It also changes the scientific understandings and classifications of this particular type of fish."It opens up these ideas of ecological questions. Muscular systems, bone systems, nervous systems all came together to form this. What led to its evolution or use?In other words, he says, "Why do we see this accumulation of so many horrible things on one fish?"The lachrymal saber is housed inside the fish's head, and they use their cheek muscles to deploy it. Though some stonefish are venomous, the saber is not.It could be a sex thing, tooSmith says he and his fellow researchers have reason to believe the saber isn't just for warding off predators: It could be a sex thing, too."There is evidence pushing towards that," he says. "They may use this in battles with other members of their species, like ram horns. It may also be involved in courtship behaviors."Oh, and the sabers glow."It's fluorescent green," Smith says. Since stonefish rely on camouflage for both protection and hunting prey, Smith doesn't think the fluorescence has a defensive purpose like, say, warning off predators.There are 134 described species of stonefish, and by Smith's observation, all of them have some form of lachrymal saber.  2202

IMPERIAL BEACH, Calif. (KGTV) - An Imperial Beach family made a chilling discovery at home: a circular piece of glass cut perfectly from the window of a toddler's nursery while he and his mother were inside.Along Emory Street, something peculiar happened last Monday. Vanya found some needed extra gravel on his property, courtesy of some nearby construction workers."They told me the homeowner had given them permission," said Vanya. The problem? Vanya owns the home and never gave permission. Vanya believes the imposter came back two days later, while his wife and one-year-old son were home around noon.RELATED: MMA fighter takes down suspected home burglar"The way she describes it, it sounded just like glass being popped in," said Vanya.Vanya's wife raced up stairs. She thought her son had broken something, but he was asleep in the master bedroom. Meanwhile, the blinds in the nursery were closed, and she thought the sound may have come from a neighbor's home. Then on Sunday, with the blinds open, the family found it: a 5-inch-diameter perfect circle cut out from the nursery window. Inside, the window lock had been snapped off.RELATED: Couple wakes up to burglary, guns drawn    "Assuming they reached in and tried to get at that," said Vanya.Vanya is grateful the intruder didn't get in. Perhaps his wife unknowingly scared the person off. Vanya remains worried about the intruder's methods.    The burglar likely used a ladder to scale the 10-foot-tall roof, before pulling out a glass cutter. The roof tiles were found damaged.RELATED: Burglars steals family heirlooms, hurts family dog"Very calculated. It scared me. Intuitively, we know they've done this before and will do it again. What happens when they encounter someone's loved one? Would they run off or commit violence against them?" said Vanya.Vanya says the man who posed as the homeowner was in his white, in his 40s or 50s, balding and wearing an orange shirt. If you have any information on the case, you're urged to call the Imperial Beach Sheriff's station at 619-498-2400. 2099
