Body length across Cycloramphidae

Longer than only 17% of all species in Cycloramphidae 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 27 to 102.1 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

Keeping one

Cycloramphus organensis is assessed as Vulnerable on the IUCN Red List. Species at risk in the wild are often covered by CITES and by national law, which decide what may be bought, sold, moved across a border or kept at all — and captive-bred and wild-caught animals are usually treated differently. Check the rules where you are before acquiring one. Nothing below is a judgement about keeping this species; it is what a published welfare standard says about space, and what the animal itself was measured doing.

No enclosure size is given here

Swiss law sets amphibian enclosure sizes family by family, and this family is not among the ones its table names. No figure is given rather than one borrowed from a different kind of animal.

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.

What nobody knows

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.
