Longer than only 42% of all species in Plethodontidae 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 412 mm. The solid rule is this animal. Every bar is a count of real species, and nothing on this figure is estimated.

Keeping one
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.
