An inhabitant of coral reefs and sea grass beds, this species is relatively common and is typically found in sparse density throughout its range.

Blue stars live subtidally, or sometimes intertidally, on fine (sand) or hard substrata and move relatively slowly (mean locomotion rate of 8.1 cm/min).

[1] The genus Linckia, as is true of other species of starfish, is recognized by scientists as being possessed of remarkable regenerative capabilities, and endowed with powers of defensive autotomy against predators:[citation needed] Although not yet documented, L. laevigata may be able to reproduce asexually, as does the related species Linckia multifora (another denizen of tropical seas, but of differing coloration, i.e., pink or reddish mottled with white and yellow, which has been observed reproducing asexually in captivity).

[citation needed] This sea star is fairly popular with marine aquarium hobbyists, where it requires a proper, slow acclimatization before entering the tank system, and an adequate food source similar to that found in its natural habitat.

It's a worthy pest control depending on how abundant the food source is, as well as such factors as the conditions of shipping, acclimatization, and water quality, this species has been kept in captivity with variable success.
