Homotrema rubrum is a colonial foraminifer. It was originally discovered by Jean-Baptiste Lamarck. It is a strong red in colour.[1] It grows on coral rubble found on the reef crest in tropical waters.[2] Ground by the surf into sand-sized pieces, it is what gives Bermuda beaches a pink tint.[3][4]
The name Homotrema rubra, which is sometimes used for this species, is not accepted.[5] The original name given by Lamarck was Millepora rubra, and the accepted name is Homotrema rubrum.[5]
