FAQ

Why can a reptile's physiological indicators not be read the way a dog's or cat's are?

Reptiles and amphibians are ectotherms and do not hold a constant body temperature as mammals do, so their normal physiological indicators carry a different meaning from those of dogs and cats and must be read together with ambient temperature and humidity. This is also why the husbandry environment column for each group is deliberately written at greater length than the others — husbandry error is the most central premise behind disease in these animals.

なぜ爬虫類の生理指標を犬猫と同じように読んではいけないのですか。 — 爬虫類と両生類はいずれも変温動物で、哺乳類のような一定の体温を持たないため、正常な生理指標の読み方は犬猫とは異なり、環境の温度と湿度と合わせて解釈する必要があります。各グループの飼育環境の欄を意図的に他より厚く書いているのもこのためで、飼育環境の誤りはこの種の動物の疾病における最も中心的な前提です。

What should I be prepared for before keeping a sulcata tortoise?

Its adult size is routinely and seriously underestimated, which is exactly why these animals are given up; tortoises are herbivorous and need large space. On lifespan, three professional zoo sources give figures that do not agree (80 to 100 years, 70 to 150 years, and 50 years or more), the methodological differences are unclear, and they should not be averaged into a single figure. Some tortoise species may outlive the keeper.

ケヅメリクガメを飼うにはどんな心構えが必要ですか。 — 成体のサイズが著しく過小評価されがちで、それがまさに飼育放棄の主な原因です。リクガメは植物食で広い空間を必要とします。寿命については、専門的な動物園 3 か所の出典が示す数値が一致しておらず（80〜100 年、70〜150 年、50 年以上）、方法論の違いも不明なため、1 つの数値に折衷すべきではありません。一部のリクガメは飼い主の一生を超えることがあります。

What matters most when keeping frogs and salamanders?

A frog's skin is highly permeable, so water quality and chemical residues on human hands are the central risks. As for salamanders, the axolotl stays aquatic for life and does not metamorphose, and some salamanders have toxic skin secretions. For both groups the authoritative sources hold little on precise lifespan year counts, and there is no single figure to quote.

カエルとサンショウウオを飼ううえで最も注意すべきことは何ですか。 — カエルは皮膚の透過性が高く、水質と人の手に残る化学物質が中心的なリスクです。サンショウウオについては、ウーパールーパーは生涯水生で変態せず、一部の種の皮膚には毒性の分泌物があります。この 2 グループは権威ある出典における正確な寿命年数の資料が乏しく、引用できる単一の数値はありません。
