A close-up of Bathynomus raksasa, a new species of "supergiant" isopod Named Bathynomus raksasa, the holotype, or physical specimen that serves as the basis for the description and name of the new species, is a male that was measured to be 36.3 cm (14.3 in) long, which puts it among the largest giant isopods ever found. The second specimen was a female measuring 29.8 cm (11.7 in). Along with being bigger on average, the team noted other differences when compared to the closest known species, Bathynomus giganteus, including smoother “skin” and different body proportions and shapes.
“The identification of this new species is an indication of just how little we know about the oceans,” says Helen Wong, an author of the study. “There is certainly more for us to explore in terms of biodiversity in the deep sea of our region.”
The team says that the discovery is an example of deep-sea gigantism, an observation that some creatures that dwell in the deep tend to grow much bigger than their relatives in shallower waters or on land. Most isopods measure less than 10 mm (0.4 in) in length, but the 20 species in the “supergiant” Bathynomus genus grow to be more than 30 times larger. S JADE 2018

All kinds of fascinating discoveries are likely lying in wait for us in the deep sea. Now scientists have pulled a new monster out of the waters off the coast of Indonesia. The creature is a new species of “supergiant” isopod, a huge marine relative of the common pillbug.
The discovery was made during the South Java Deep Sea Biodiversity Expedition 2018 (SJADES 2018). At depths between 950 and 1,260 m (3,115 and 4,135 ft), the team found two specimens of giant isopods that were soon determined to belong to a new species.

In the past few years we’ve seen many new species reeled in from the deep oceans, including the deepest-dwelling fish in the world, hairy-chested “Hoff” crabs, eye-catching neon fish, and the longest animal ever recorded – a floating zooid colony measuring 47 m (154 ft) long.
The new study was published in the journal ZooKeys.

Remind me never to say “this tastes like sh&%!” around Red Badger! ;)
If something ever moved or propelled itself in any way at some point, then Chinese will eat it.

You can thank me later...
How about that!
We would play with them all the time as a kid. We never hurt them. They were very cool.
A land-based crustacean? Amazing.
And very important to the eco-system, too. They eat nearly anything and help decompose stuff back into the soil....................
