INOKASHIRA PARK ZOO
For the full size image, click on the painting. (March 4, 2008) SPECIAL REPORT!!The domestic frogs have been already here.
Unfortunately in Tokyo, local amphibians are diminishing. The sewage from the drain contaminates their habitats. Wetlands are disappearing by expanding residential area. The zookeeper, Hiroshi Arai also pointed out another reason of disappearing aquatic creatures. that brooks and streams which connect to wetlands and small ponds are cut off.
“Frog, amphibian and water insect move to another place for mating, laying eggs or looking for more suitable habitat. But it is very hard for them to move from one wetland to another”, said he. Could frog be drowned?
The Wrinkled Frog is easier to rear in a captivity because they don’t take a big jump. The zoo has more than 200 frogs, which have left water to land after growing legs from tadpoles. The Eastern-Japanese Common Toad (Bufo japonicus formosus) is also bred in the zoo. The frog is quite common in this local area, but it is not easy to rear it in captivity. The frog needs both water and land, but young frog could be drowned if you fill water too much. So zookeepers are always careful about the population of frogs and how fast they grow in the tank. Inokashira Zoo breeds and rears the Japanese Fire Belly Newt with corporation by Kasai Rinkai Aquarium. This newt used to be able to be found even in downtown Tokyo, but it is only found in suburb area now. Even though it is not endangered species yet, the zoo wants visitors to discovere the fascinating newt. The hungry frog is the super star.The zoo also displays the Forest Green Tree Frog (Rhacophorus arboreus), The Japanese Tree Frog (Hyla japonica) and others are exhibited. Among them, the American Bullfrog is very popular. His large body catches the visitors’ eyes. He was found in a residence nearby. He had a big boil when he came to the zoo. The boil made him decline his appetite. So, he was treated and very healthy then. He has a hearty appetite and sometimes he eats too much. He eats a whole mouse sometimes otherwise he gets slimmed down. Crayfish is his daily meal in the zoo. If you are lucky, you can see him devouring crayfish with his tongue.
Stop and take a look. They are very rare now!The Aquatic Life House of Inokashira Zoo has more. The Miyatanago (Tanakia tanago) is the national natural treasure. The Musashitomino is the little fish, which is endemic to Kumagaya city in Saitama. Maybe because they are little and hiding behind water plants, people easily pass by the tank. The zookeepers relocate the water plants and stones or change the light effect to get the visitors attention to the very rare fish.
The zookeeper Arai, who has been the specialist of the aquatic animals, said, “I hope that the campaign of 2008 – Year of the Frog would generate the public awareness about the severe environment damage around frog and amphibian.” Inokashira Zoo has held special exhibitions and events related to Year of the Frog in 2008.
