Bizarre New Species of Crabs and a Giant Sea Cockroach Discovered in Waters Off Indonesia

A crab with green googly eyes, another with "ears" resembling peanuts, and a species of giant sea cockroach are among the dozen new kinds of crustaceans discovered by scientists in the waters off Indonesia, Channel News Asia reports.

These finds are the result of a two-week expedition by Indonesian and Singaporean scientists with the South Java Deep Sea Biodiversity Expedition (SJADES 2018), which involved exploring deep waters in the Sunda Strait (the waterway separating the islands of Sumatra and Java in Southeast Asia) and the Indian Ocean. Using trawls, dredges, and other tools, researchers brought a huge variety of deep-sea life to the surface—some species for the very first time.

"The world down there is an alien world," Peter Ng, chief scientist of the expedition, told Channel News Asia. "You have waters that go down more than 2000 to 3000 meters [9800 feet], and we do not know … the animal life that's at the bottom."

The giant sea cockroach—technically a giant isopod, also nicknamed a Darth Vader isopod—is a new species in the genus Bathynomus, measuring almost a foot long and found more than 4000 feet deep. The isopods are occasionally seen on the ocean floor, where they scuttle around scavenging for dead fish and other animals. This marked the first time the genus has ever been recorded in Indonesia.

Another find is a spider crab nicknamed Big Ears, though it doesn't actually have ears—its peanut-shaped plates are used to protect the crab's eyes.

More than 800 species were collected during the expedition, accounting for 12,000 individual animals. Researchers say it will take up to two years to study all of them. In addition to the 12 species that are completely new to science, 40 were seen for the first time in Indonesia. Creatures that the scientists dubbed a chain-saw lobster, an ice cream cone worm, and a cock-eyed squid were among some of the rarer finds.

Nicknamed the "Chain-Saw Lobster," this creature is a rare blind lobster, found only in the deep seas.

Researchers took to the giant sea cockroach quickly, with some of the crew members reportedly calling it “cute” and cradling it like a baby. Check out Channel News Asia Insider's video below for more insight into their creepy finds.

Scientists Find Fossil of 150-Million-Year-Old Flesh-Eating Fish—Plus a Few of Its Prey

A fossil of an unusual piranha-like fish from the Late Jurassic period has been unearthed by scientists in southern Germany, Australian news outlet the ABC reports. Even more remarkable than the fossil’s age—150 million years old—is the fact that the limestone deposit also contains some of the fish’s victims.

Fish with chunks missing from their fins were found near the predator fish, which has been named Piranhamesodon pinnatomus. Aside from the predator’s razor-sharp teeth, though, it doesn’t look like your usual flesh-eating fish. It belonged to an extinct order of bony fish that lived at the time of the dinosaurs, and until now, scientists didn’t realize there was a species of bony fish that tore into its prey in such a way. This makes it the first flesh-eating bony fish on record, long predating the piranha. 

“Fish as we know them, bony fishes, just did not bite flesh of other fishes at that time,” Dr. Martina Kölbl-Ebert, the paleontologist who found the fish with her husband, Martin Ebert, said in a statement. “Sharks have been able to bite out chunks of flesh, but throughout history bony fishes have either fed on invertebrates or largely swallowed their prey whole. Biting chunks of flesh or fins was something that came much later."

Kölbl-Ebert, the director of the Jura Museum in Eichstätt, Germany, says she was stunned to see the bony fish’s sharp teeth, comparing it to “finding a sheep with a snarl like a wolf.” This cunning disguise made the fish a fearful predator, and scientists believe the fish may have “exploited aggressive mimicry” to ambush unsuspecting fish.

The fossil was discovered in 2016 in southern Germany, but the find has only recently been described in the journal Current Biology. It was found at a quarry where other fossils, like those of the Archaeopteryx dinosaur, have been unearthed in the past.

These Are America's 50 Most Rat-Infested Cities

New York City, home to the subway pizza rat, is surprisingly not America’s most rodent-infested city. That dubious honor goes to Chicago, according to a new analysis spotted by Thrillist.

A breakdown of the “50 Rattiest Cities” in the U.S. has been compiled by Orkin, a pest control service with locations across the country. The company tallied up the number of commercial and residential rodent treatments it carried out in each city over a period of 12 months (September 15, 2017 to September 15, 2018) and then ranked them. While the evidence is anecdotal, as it comes from just one company, it does reveal the areas where rat exterminators are in high demand.

This is the fourth year in a row that Chicago has been named the country’s rattiest city. Orkin isn’t the first to notice the city’s rodent problem, either. In July, Chicago was reportedly dubbed the “rat capital of the U.S.” by apartment search service RentHop. It reportedly received more rat complaints than any other city last year—nearly 51,000 total. According to RentHop’s analysis, New York City came in second place, followed by Washington, D.C. and Boston.

That isn’t too far off from Orkin’s latest analysis. New York comes in at third place, just after Los Angeles, and Washington, D.C. is fourth. The biggest boom in rat populations was seen in Portland, Maine, which jumped 19 spots from last year. Chance Strandell, residential service manager for Maine Pest Solutions, told New England Cable News that milder winters may be extending the rats’ breeding period. However, it’s unclear why rats seem to be multiplying in Maine in particular.

One pregnant rat can birth up to 12 babies in a single litter, and those pups can begin reproducing at just two months old. “So after a year, a busy pair of rat parents can have 15,000 descendants,” reports KATU in Portland, Oregon (number 24 on Orkin’s list).

Charleston, West Virginia, has also been teeming with rodents, having risen 17 spots from last year. Check out the full list of the 50 most rat-ridden cities below—and if you have musophobia (a fear of rats or mice), you may want to plot your move to one of the cities toward the bottom of the list.
