Scientists from Indonesia and Singapore have discovered not less than 12 species of hermit crabs, shrimp, lobsters and crabs which are recent to science in deep waters off the coast of West and South Java.
The South Java Deep Sea Biodiversity Expedition 2018 (SJADES 2018), the primary expedition of its kind jointly organized by the 2 countries, also yielded over 40 species, a brand new record for Indonesia.
The numbers often is the tip of the iceberg, as researchers are currently analyzing 12,000 specimens collected in the course of the 14-day expedition. On March 23, thirty-one scientists and a 25-person support crew sailed from Jakarta on the Indonesian research vessel Baruna Jaya VIII. They swam counterclockwise towards Cilacap in South Java and back, collecting samples at depths averaging between 800 m and a pair of,100 m.
About 800 species have been discovered and a few of those collected include sponges, jellyfish, starfish, sea urchins, worms, crabs and fish.
This study also identified 12 recent species.
Two years later, the team confirmed that the expedition had identified one other recent species.
Yes, it’s that cockroach-like creature.
This supergiant isopod has now been given a scientific name Bathynotic mercuryIN. For most individuals, it is a nightmare – an enormous crustacean pulled from the depths of the ocean that has rightly earned the nickname “the deep-sea cockroach.”
The enormous creature, which the team also named Darth Vader’s isopod, is just one among countless unusual species found during an expedition off the coast of an Indonesian island. Scientists also discovered a brand new kind of hermit crab, a shrimp with shiny eyes and a crab with fluffy spines.
In an Instagram post, researchers involved within the mission wrote that staff “couldn’t contain their excitement once they finally saw one,” referring to the deep-sea cockroach.
Scientists from the National University of Singapore (NUS) and the Indonesian Institute of Science (LIPI) led the expedition lasting 14 days from March to early April.
The area covered included an extended stretch of the Indian Ocean off the southern coast of Java, in addition to the Sunda Strait separating the island from Sumatra.
But the invention of species completely recent to science “tells us that there are things occurring on this a part of Indonesia that we do not learn about,” said Ng, who co-led the expedition.
During the cruise from Jakarta to the town of Cilacap in southern Java and back, researchers examined 63 sites.
Scientists said in an announcement that three recent species of spider crabs were discovered in the course of the expedition.
One of them had a watch protection plate that resembled large ears, while one other was light orange in color.
According to Indonesian scientist Dwi Listyo Rahayu, also a crab expert and co-chair of the expedition, one other discovery was a brand new species of hermit crab with vibrant green eyes.
Scientists say one among the brand new shrimp species had shiny eyes that reflected light.
scientists will conduct detailed studies of over 12,000 creatures from 800 species that they caught in the course of the expedition.
This huge discovery will probably pave the best way for a few years of research.
The team plans to publish their findings in 2020.
