Distribution

This species was described from Honolulu, Oahu, Sandwich Islands. It has been reported widely in the Indo-Central Pacific and from the Pacific coast of Mexico and the Canary Islands. This wide distribution suggests that it is probably a species complex, but it has been considered to be an invasive species.^[5]

Description

The maximum recorded body length is 50 mm^[6] or up to 120 mm.^{[citation needed]}

Ecology

Minimum recorded depth is 0.5 m.^[6] Maximum recorded depth is 63 m.^[6]

Tayuva lilacina feeds on Haliclona caerulea according to the in situ observations on the Pacific coast of Mexico.^[7] It is probably highly specialized on this sponge.^[7]
