Glowing Cockroach Mimics Toxic Beetle. The cockroach species Luchihormetica luckae emits a green glow. A glowing green cockroach would seem much easier to kill than our more familiar kitchen pests, but this particular insect evolved its own set of lights to avoid exactly such predatory attention, according to a new study.Luchihormetica luckae glows to mimic the bioluminescent click beetle, whose glow warns predators of its toxicity.Found in rain forests around an active volcano in Ecuador, the inch-long (2.5-centimeter-long) cockroach is unique for a few reasons, scientists say. For one thing, while many life-forms have evolved their own flashiness, most are found in the deep-sea—making bioluminescence a relatively rare trait on land. But L. luckae is particularly rare, in that it glows to mimic another insect. Other uses of bioluminescence in the insect world, as in the case of the common firefly, are more attuned to attracting mates—lighting up to find love in the dark simply saves time. Unfortunately, it also makes one much more visible to predators. “Bioluminescence is like any evolutionary tool—there is no single use for it. It can attract, deter, or even be used as an invisibility cloak of sorts,” said Olivia Judson, an evolutionary biologist and author of Dr. Tatiana’s Sex Advice to All Creation.
This phenomenon in nature is called bioluminescence and is a trait possesed only by a small group of creatures. This is a bioluminescent form of fungi.
Other bioluminescent organisms include the firefly, the fungus gnat, deep sea flashlight fish, female anglerfish, Cookiecutter sharks, and squid.
Black Panther – a typical melanistic color of any species of big cats.
In Latin America, a Black Panther is just a melanistic jaguar; in Asia and Africa it’s a black leopard, and in North America it may be black jaguars or pumas. By the way, it has been proven that black cats have a more balanced nervous system and faster response than other colors of cats.
Vampire Squid’s Surprising Diet Revealed despite its ghoulish name and looks, the vampire squid (pictured, an individual in 2004) isn’t a bloodthirsty terror of the deep after all, a new study says.Instead, the nightmarishly named species browses on “marine snow”—dead plankton, algae, fecal matter, goo, shells shed by tiny crustaceans, and other detritus.The squid gather the food particles using two long, hair-lined filaments before wrapping the bits into meal-size mucus balls, according to undersea video footage, live lab observations of captive vampire squid, autopsies, and examination via electron microscope.”Because of its fearsome appearance, and because all other cephalopods living today are predators, it was thought that [vampire squid], too, were hunting for living prey,” said study co-author Henk-Jan Hoving of the Monterey Bay Aquarium Research Institute (MBARI) in California.”We have now found the opposite.”
