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]
