Bathynomus Raksasa

  • The Bathynomus raksasa is a giant isopod (phylum: Arthropoda) in the genus Bathynomus.
  • It is described as the “cockroach of the sea”. The epithet is the Indonesian word “raksasa” for giant, alluding to its enormous size.
  • The giant isopods are distantly related to crabs, lobsters, and shrimps (which belong to the order of decapods), and are found in the cold depths of the Pacific, Atlantic, and Indian Oceans.
  • It has 14 legs but uses these only to crawl along the bed of oceans in search of food.
  • As a scavenger, Bathynomus raksasa eats the remains of dead marine animals, such as whales and fish, but can also go for long periods without food, a trait that it shares with the cockroach.

Why this cockroach matters?

  • Bathynomus raksasa is the sixth ‘supergiant’ species from the Indo-West Pacific and is one of the largest known members of the genus.
  • The discovery takes the number of known giant isopods to 20.
  • As the Bathynomus raksasa reveals its secrets, it will contribute towards increasing knowledge about the deep.
