cirrus

The most likely explanation is the presence of thick but uneven water ice clouds, similar to cirrus clouds high in Earth's atmosphere -- an unexpected complication.

Wind shear can occur in wispy cirrus clouds or even in clear air near thunderstorms, as differences in temperature and pressure create powerful currents of fast-moving air.

The remaining, thinner cirrus clouds would allow more long-wave radiation emanating from Earth to escape to space.

In very young specimens, the cirri are only barred with purple.

Of two specimens in another and older set in the British Museum, from an unknown locality, both had shields on the segments of the cirri, but only one had the large plate on the prosoma.

Finally, I may remark that the whole of the body and the cirri are capable of many diversified movements.

This species agrees with P. elegans, in the presence of the singular elbowed teeth, on some of the spines in the first three pairs of cirri.
