Final answer:

The mite known as "walking dandruff" is the cheyletiella mite, a parasitic mite that causes cheyletiellosis. Unlike the common dust mite, cheyletiella mites are larger and can be seen moving on the skin, which resembles moving dandruff flakes.

Explanation:

The mite commonly known as "walking dandruff" refers to cheyletiella mites, which are superficial parasitic mites often found on pets like dogs, cats, and rabbits but can also infest humans. These mites can cause a condition known as cheyletiellosis or walking dandruff, where it appears that dandruff is moving on the host's skin due to the movement of these tiny mites. These mites are part of the larger ecosystem of microorganisms and arthropods like the dust mite and demodex species that inhabit environments shared with humans.
