Scientists from the National University of Singapore and the Indonesian Institute of Sciences revealed their findings on the brand new large isopod species (each female and male specimens) that had been initially collected off the southern coast of West Java in Indonesia throughout a joint deep-sea biodiversity expedition in 2018.

“Throughout an expedition, there are some animals which you discover unexpectedly, whereas there are others that you simply hope to seek out,” Lee Kong Chian Natural History Museum posted on Instagram. “One of many animals that we hoped to seek out was a deep-sea cockroach affectionately generally known as Darth Vader Isopod.
