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.
During an expedition, there are some animals which you find unexpectedly, while there are others that you hope to find. One of the animal that we hoped to find was a deep sea cockroach affectionately known as Darth Vader Isopod. The staff on our expedition team could not contain their excitement when they finally saw one, holding it triumphantly in the air! #SJADES2018
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.
