Observed crab behavior towards starfish in tiptoe posture
Compared behavior with responses to a slowly elevated stone tile
Measured number of crabs entering spaces beneath starfish and tile
40% of crabs entered space beneath the stone tile
33% of crabs entered space beneath the starfish
No significant attraction signals were detected from starfish during trials

Gushiken et al. (2026) studied this question.
