For Podacris muralis, their head position significantly correlated with the vertical component and total intensity of the magnetic field. Also, the way the lizards were aligned significantly correlated with the rate of change in geomagnetic values. Yet, there was no correlation between geomagnetic values and the lizards' positions and their head directions weren't correlated to rate of change in geomagnetic values. For Podacris lilfordi, statistically significant findings for body alignment and head direction while basking along with geomagnetic field values were calculated. The rate of change in geomagnetic values correlates with body alignment and head position.
So, these certain lizards align their bodies to orient with respect to the geomagnetic field axis. This doesn't mean that these lizards have awareness of the geomagnetic field, but still proves their ability to use magneto-reception. Other studies should be done to eliminate the possibilities of wavelength detection and also the possible affects of polarity.

Interesting article! What might these magnetoreception abilities allow these lizards to do/
