Homotrema rubra explained

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.
