ウナギのウロコ

_8

ドジョウのウロコは思った程難しくなく
意外とあっさり見ることができたことを記憶しています。

ところが、ウナギのウロコはいろいろあって10年近くになるでしょうか?
ずっとできずじまいでした。

ところが、以前出版されていた『科学の実験』という雑誌の臨時増刊号に見事なウナギのウロコの写真が載っていました。皮膚に埋め込まれていて容易に撮影できないとのこと。
そこでは、皮をとってから水酸化ナトリウムで溶かした上で、筋肉をグリセリンで透明にしてウロコがきれいに配列したまま撮影する手法が書かれていました。

まずは、水酸化ナトリウムに入れてほとんどどろっと溶けてしまった方の底に残ったものを見てみました。
おそらくこれがウナギのウロコだと思われます。

うなぎにウロコがあるのは、わかりますが、ウサギにウロコ?

皮をはがれてウロコを採取されたのですか?傷は治るのでしょうか?

書き込みありがとうございました。
一瞬、どこかでウサギと書いたのだろうかと探したのですが。・・・・・ありませんでした。
