World First Live Exhibition of A Snail with "Iron Foot" and A Shrimp with Heat Sensor on Its Back in Japan
The snail’s foot is armored with iron-mineral scales, no other animal is known to use iron sulfides in this way. The shrimp can sense heat radiation from high temperature materials.
These animals are collected from Kairei hydrothermal vent field, some two thousand meters under the Indian ocean. From 30th november 2009, the world first live exhibition is held in ENOSHIMA AQUARIUM (新江ノ島水族館 ) in Kanagawa prefecture, Japan.
The shrimp (Rimicaris kairei) is about 2 cm long. It was found living close to the hydrothermal vents in large number.
The star of the exhibition is the 4 cm long Scaly-foot gastropod (Crysomallon squamiferum ). The snail was discovered in 2001 by American researchers. The snail’s foot is armored with iron-mineral scales. It even responses to magnets. The Aquarium is hoping that low water temperature and low oxygen exhibition tank could keep the creatures alive as long as possible.
Since these creatures in exhibition are out of their natural environment, the exhibition could be very short. If interested, go and visit them as soon as possible.
