The species has only been recorded to live in coral reef habitats off the coast of Moorea, Society Islands, French Polynesia. [2] Unlike other species within the genus, M. mcphersonae is associated exclusively with marine coral reef habitat. [2]
The tiger pistol shrimp lives in burrows in symbiosis with certain goby species such as Cryptocentrus cinctus, Amblyeleotris guttata or Stonogobiops yasha. The shrimp digs and maintains the burrows which are the dens for both animals, while the goby acts as a watchman, warning of danger the shrimp cannot see due to poor eyesight. [8]

In the narrower sense, Synalpheus occur in the eastern Pacific where they are most plentiful and probably originated, and to a lesser extent in the Atlantic and the Indian Ocean; the species placed in Zuzalpheus occur mainly in the western Atlantic where their lineage probably originated, and to a lesser extent in the eastern Atlantic and Indian Ocean, and the eastern Pacific.

[2] [1] The average size can range depending on the population, with the smallest collected from Fakaofo being 12 mm long and largest known specimen being collected from Jaluit Atoll at 17 mm long.
