日本のトビハゼ(ムツゴロー)は埋立てと環境汚染の影響で準絶滅危惧種。トビハゼはアジア、アフリカ、豪州の熱帯・亜熱帯の干潟に生息。鰓呼吸と皮膚呼吸ができるので波打ち際で陸上生活。ケアンズは干潟やマングローブ林が多いのでトビハゼの仲間が数種類います。大型種は体長が30cm以上もあります。オスはメスよりも背ビレが大きく派手で、求婚のダンスを踊ってメスを巣穴に誘います。マングローブ林の木道から生態が観察できます。

Mudskipper
Tue. September 15 : fine
Mudskippers in Japan are designated as the sub-endangered species due to the influence of landfill and environmental pollution. Skippers live in the tropical and subtropical tidal wetland in Asia, Africa and Australia. Using both their gill respiration and skin respiration they have land life on the surfside. As there are a lot of tidal wetland and mangrove forests in Cairns you can see several different species of mudskippers. The biggest kind is more than 30cm long. The male has larger and showier back fins than female and it dances to invite a female into his nest. You can observe it from the wooden path in the mangrove forest.

There is a huge mudskipper at the children’s park on the City coast. I will write about great Ichiro tomorrow.
