What is the function of syndactyly in bandicoot hind digits?

Meticulous grooming, such as removing external pests like ticks.

Syndactyly is a unique physical feature observed in the feet of bandicoots, specifically referring to the condition where two of their hind digits are fused together, emerging as a single toe structure bearing two claws. This structure is not primarily related to locomotion or digging, although the hind legs are powerful for leaping. Instead, this specialized foot anatomy is adapted for very precise and meticulous self-care. The fused digits and associated claws are utilized effectively for grooming activities, which includes the important task of scraping or removing external parasites, such as ticks, from their fur, thereby contributing to their overall health and hygiene.
