Biologic evolution

The doubt has come out.

The right is large. its.. scissors of the male of Japanese Freshwater CrabThe left is small.

The picture of figure wrote the place where scissors when the copulation of Sesarmops intermedium was done were placed.

It is a female that the color draws blacking it.

The position at the left of scissors is uncertain because it doesn't observe it still accurately.

I want to observe the copulation of the crab in detail this spring.

疑問が出てきた。


それはサワガニのオスのハサミは右が大きい。左は小さい。

図の絵はベンケイガニの交尾をする際のハサミを挟む所を書きました。

色が黒く描いた方が雌です。

まだ正確に観察をしていないために、はさみの左側の位置が不明です。

今春、蟹の交尾を詳しく観察したいと思っています。
