Name the actual study
Starck and colleagues published their paper in PLOS ONE on 15 August 2022. They compared inner-ear anatomy in four spider morph ball pythons with wobble and five wildtype specimens. The work was descriptive and exploratory, not a survey of every pet or a consumer colour-identification test.
Keep the sample limits beside the finding
The spider morph animals had been presented to a clinic for neurological symptoms. The authors discuss possible selection bias and say the small sample prevented statistical analysis. They found anatomical differences associated with the condition in the animals studied. This site does not turn that into a prevalence estimate or a verdict about every morph.
A pattern is not a diagnosis
The paper does not allow a website to determine an individual snake’s inner-ear anatomy, genetics, health or welfare from a name or image. This page offers no morph matching, balance test, movement demonstration, examination or clinical procedure. Do not provoke a response to compare with the research.
No neat appearance gives an all-clear
The absence of an obvious sign in a picture is not a health certificate. Concern about movement, feeding, injury or other change needs prompt advice from a reptile-experienced veterinarian. Do not wait for a matching result or app answer. No purchase, breeding or keeping decision is approved here.
