Heart sea-urchin was collected from Thoothukudi coast of Gulf of Mannar, Southeast coast of India on April 11, 2014. This specimen was classified as Maretia planulata (Lamarck, 1816) belonging to the family Spatangidae. The most speciose echinoid orders, Spatangoida and Clypeasteroida, are abundant in the Indo-West Pacific and Caribbean. This genus and species are newly recorded in two distinct Indo-Pacific marine zones. One specimen was caught at the depth of 310 m as an incidental by-catch. It was found in tropical waters from about 08º 35’ 22.5”N 78º 27’ 40.9 E/310 m from Thoothukudi fishing harbour, southeast coast of India.
