Body length across Ranidae

Longer than only 22% of all species in Ranidae anyone has measured.

The bar is the rank itself: its length is the share of the family this animal exceeds. The chart below is the family’s real spread, on a logarithmic scale because body length here runs from 20 to 203 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

Keeping one

Land
54 × 27cm
Water, at least 11 cm deep
27 × 27cm

Minimum, and for two animals — which is how the standard states it. Bigger is always better. Around 27 cm tall on average.

The standard gives 10 × 5 body lengths of land and 5 × 5 of water, for two animals.

For each further animal the standard asks for another 11 × 11 cm of land and 11 × 5 cm of water.

Swiss Tierschutzverordnung (TSchV), SR 455.1, Anhang 2, Tabelle 6 — legally binding minimum enclosure sizes for amphibians, given as multiples of total body length and stated for two animals.

From this animal’s own snout-vent length, which for a frog is its body length of 2 in (53.6 mm) — how this is worked out.

These are not gaps in our research. No scientific dataset records them for this species — and saying so is information you cannot get from a reference that simply leaves a field out.
