サバクゴファーガメ – Desert Tortoise


先週は記念すべき週となりました。初めてサバクゴファーガメに遭遇することができたからです。しかも、青年カメと子供カメ。場所は Red Cliffs Desert ReserveChuckwalla trail です。 – It was a memorable week last week.  It’s because I met Desert Tortoises, a young adult as well as a yearling on Chuckwalla trail in the Red Cliffs Desert Reserve.

子供と青年の違いがよくわかる所は甲羅と足の爪です。甲羅のそれぞれの模様の中にできる輪の数で年齢を図ることもできると言われています。輪の数の半分が年齢なので青年は6-7歳ぐらい、子供は1-2歳。方法はあくまでも目安なので正確とは言えないとも言われています。 – I noticed that two major parts of their body show differences between an adult and a child.  One is its shell.  The number of rings inside the patterns divided by two is the age.  For the case of these tortoises the ages, based on my counts, are 6-7 years old for the young adult, and 1-2 years old for the young one.

もう一つは足の爪。青年の方はすでに黒くなっていますが、子供はまだ透明感があります。 – Another difference is the nails on their toes.  The nails of the young adult are already black but the child’s nails are still transparent.

それぞれの大きさは、青年が 30cm ぐらいで、子供は 10cm ぐらいだったでしょうか。50-60 年、生きると言われています。また、成長しきるには 15-20 年かかります。医療の発達が今ほどなかった頃の人間の寿命に似てますね。- The length was about 30cm for the young adult, and 10cm for the yearling.  Their life span is about 50-60 years, and to reach maturity, it takes 15-20 years.  It’s similar to a human life span before all the medical technology came in.

最後に、1分のビデオを作って見たので見てください。- Lastly, I want to share a one minute video with you about them.
