A new inhabitant of the Japanese aquarium Aquamarine Fukushima – a blood-sucking marine isopod parasite from the genus Rocinela – has already become popular. It looks like salmon sushi, Vice writes.
The Japanese aquarium “Aquamarine Fukushima” in the city of Iwaki shared a snapshot of its most unusual inhabitant. It is a marine isopod (or isopod), a deep-sea crustacean that resembles salmon sushi in shape.
Isopods usually feed on dead and decaying animals, but not Rocinela. They tend to be parasites that build cozy homes on the backs or in the viscera of other sea creatures. Most of this genus appear dull and brown, according to Mai Khibino, the aquarium keeper. However, the inhabitant of “Aquamarine Fukushima” differs from its relatives in bright colors.
Earlier, fishermen caught an unusual representative of isopods in a net near the coastal town of Rausu in Hokkaido, the northernmost island of Japan. According to Khibino, the creature lived at a depth of 800 to 1200 meters, and when it was found, it had just eaten – it had a full belly. Unfortunately, it is impossible to know exactly what a 3cm fish ate to get such a bright raw fish color.
To date, more than 10,000 isopod species have been described whose diets, habitats and sizes vary greatly.
