Aspects Of Taxonomy And Population Parameters Of Holothuroid (Aspidochirotida: Holothuroidea) In Pulau Kapas, Terengganu, Malaysia

This study aimed to investigate some aspects of the taxonomy of holothurian species and population parameters of the dominant species found in Pulau Kapas. Observations by SCUBA on the density and abundance of holothurians were carried out using transect lines in five stations once a month for 1...
