ヒロのコンドーの前の岩場で、初めてカニを見たときびっくりしました。日本では見たことがないほど、またちょっと気味が悪いほど黒いではありませんか? よく考えてみると、ハワイ島の海岸は玄武岩で真っ黒な色をしています。また、海岸にはサギやシギがたくさんいます。黒くて目立たないカニだけが生き残リその遺伝子を子孫に伝えてきたのでしょう。そして臆病ですばやいこと。まさにダーウィンの進化論の世界です。
I was very surprised when I saw crabs at rocky lagoon in front of my apartment because they were really black, a little bit sickening color. I never have seen such colored crab in Japan. But consider well, the beach of Big-island is black color by Basalt lava and many herons and snipes are there. So only black and inconspicuous crabs could survive and inherited their gene to descendants. They are also cautious and nimble. This is exactly the world of the Evolution theory of Darwin
