Alpheus est un genre de crevettes marines de la famille des Alpheidae.
Symbiose avec les gobies Les espèces du genre Alpheus s'associent quelquefois à d'autres organismes, notamment des colonies de corail, ou certaines espèces de gobies.
Par exemple le Gobie de Steinitz ou Gobie commensal (Amblyeleotris steinitzi) s'associe avec la crevette Alpheus djeddensisSealifecenter.com. Le gobie creuse un « terrier » dans le sable que la crevette entretient, et dans lequel la crevette et les gobies vivent. La crevette a mauvaise vue comparativement au gobie, mais si elle le voit ou le sent brutalement rentrer dans le trou, elle le suit. Le gobie et la crevette restent en contact, la crevette utilisant ses antennes et le gobie effleurant la crevette avec sa queue lorsqu'il est alarmé. Chacun des deux gagne de cette relation : la crevette obtient un avertissement à l'approche d'un danger, et le gobie obtient une maison sûre et un endroit dans lequel pondre ses œufs.
Certains aquariophiles reproduisent ce type de symbiose en aquarium.
