Siphusauctum gregarium, a 500-million-year-old filter feeder, was the length of a dinner knife with a bulbous "head" containing a feeding system and a bizarre gut. Instead of filtering water past its feeders externally, S. gregarium appears to have pumped water through its tuliplike head, capturing any food particles that passed through, study researcher Lorna O'Brien of the Royal Ontario Museum in Canada told LiveScience. Scientists aren't sure where this unusual creature fits into the evolutionary tree.
Scientists say the microscopic creature looks like it might come from the genus Vorticella. Its secret talent is coiling and uncoiling its springy stalk at a speed of 3.1 inches (8 centimeters) per second, the equivalent of a human getting across three football fields in that amount of time.
Although other primates (including humans) have been known to practice cannibalism, scientists had never before seen a gray mouse lemur so much as eat another mammal, according to ScienceNow, which reported the creepy meal. Scientists documented the case in the American Journal of Primatology.
Illacme plenipes is the world-record holder for "leggiest creature." It's found, bizarrely, in only a 1.7 square mile (4.5 square kilometer) area in northern California — doubly odd, because the creature's closest living relative calls South Africa home. The millipedes may have spread out across the globe when most of the land on Earth was part of one supercontinent, Pangaea. When the supercontinent broke apart 200 million years ago, the relatives could have been separated, explaining the long-lost connection.
Pliosaurus funkei, as it is now properly known, was 40 feet (12 meters) long with a 6.5-foot (2 m)-long skull."They had teeth that would have made a T. rex whimper," study researcher Patrick Druckenmiller, a paleontologist at the University of Alaska Museum, told LiveScience
Zoo staff had been trying to breed the rare aquatic snake Erpeton tentaculatus for four years before success. These bizarre Southeast Asian serpents are the only snakes with two little tentacles on their snouts. These tentacles act like whiskers to help the snakes sense vibrations from swimming fish.
The species is named Phallostethus cuulong and is one of few fish that fertilizes eggs inside the female's body rather than outside. The nasty-looking hook appendage seems to have evolved to ensure the male's sperm get to the right place.
This truly bizarre creature had never been observed by human eyes before 2000, when a team from the Monterey Bay Research Aquarium Institute in California took a remotely operated submersible into 2-mile (3.5-km)-deep waters off the central California coast. They later captured two specimens of the animal, which is scientifically called Chondrocladia lyra, and took 10 more video observations, reporting their analysis of the new species in October in the journal Invertebrate Biology.
The acids allow the worms to break down and absorb the bone, the researchers explained. But that's just the tip of the weirdness iceberg for these amazingly adapted worms. The females grow about an inch (3 cm) long, but males never grow larger than 1/20th of an inch (1 millimeter). They seem to live in the gelatinous tubes covering the females, serving no purpose but to fertilize her eggs
The turtles excrete urea, the main component of urine, through the gills in their mouths, a talent previously seen only in fish, the scientists reported in October in the Journal of Experimental Biology. This may be an adaption to the turtles' salty environment. Because they can't get enough freshwater to wash urea out through their urine, they transport it through their gills and then rinse their urea-filled mouths out with saltwater. And you thought flossing was bad.
