SEA CUCUMBER (ECHINODERMATA: HOLOTHUROIDEA) DATABASE
Last update: Friday - 30th September 2016, 28 Zulhijjah 1437
This website has been launched since 19th April 2010
The Sea Cucumber (Echinodermata: Holothuroidea) Database is part of the outcomes of a national project entitled “Systematics of Sea Cucumbers of the Genus Holothuria (Aspidochirotida: Holothuriidae) and Phylogeography in H. leucospilota” (January 2007 – December 2008) supported by the Fundamental Research Grant Scheme (FRGS) Category A for cycle 01/2006 (FRGS0106-25) through the sponsorship of the Department of Higher Education, Ministry of Higher Education (MOHE), Malaysia. This database has been launched and maintained by the Sea Cucumber (Echinodermata: Holothuroidea) Research Group which was formed under the Institute of Oceanography and Maritime Studies (INOCEM), KOS, IIUM. The database was launched on-line for two times. The first launching was on 1st of January 2009 at http://sea.cucumber.kos.iium.googlepages.com/. After more than a year, the database was launched again on 10th of April 2010 at a new link i.e. http://sites.google.com/site/malaysianseacucumber/ for better site layout and data storage capacity. At the moment, the database has 11 sections: HOME page, Award & Recognition, Contact Us, Copyright & Reference, PADI SCUBA Team, Research & Consultancy, Publications & Research History, Research Student, Research Supervision, Researcher & Collaborator, and Useful Links. This easy-to-access on-line reference has enabled a lot of people around the world including business owners, academics, and researchers to refer to and be up-to-date with available research and information on Malaysia’s sea cucumbers. The database has been recently recognised at the national level as well as at the international level. It is linked to the Malaysia Maritime Database (http://marin-dbase.com/) - a national maritime database in Malaysia which contains various information on the expertise, experts, institutions, and companies pertaining to maritime education and industries. At the international level, the database can be accessed worldwide from the US National Science Foundation (NSF)-sponsored project i.e. the Systema Aspidochirotidae database (http://www.guammarinelab.com/peetcukes/index.html).
SEA CUCUMBERS IN MALAYSIA - GENERAL INTRODUCTION
Sea cucumber (aka sea cuke), holothurian or holothuroid belongs to phylum Echinodermata. This soft-bodied marine-dwelling echinoderm from class Holothuroidea is unique due to the existence of evolved skeleton (i.e. ossicles or spicules) and ancient-looked respiratory system called respiratory tree possessed by a few species.
In Malaysia, sea cucumbers from other than family Stichopodidae e.g. genera of Holothuria, Actinopyga, Pearsonothuria, and Bohadschia are commonly known as bat, balat, and timun laut. They are also sometimes known as brunok, and hoi sum or hai shen by the Chinese community, which means "sea ginseng" - a reference to its healing properties. Stichopus species, frequently used as the main raw material in the traditional medicine (i.e. gamat oil and gamat water/fluid) especially in Peninsular Malaysia, West Malaysia are locally known as gamat. Thelenota species e.g. Thelenota ananas and Thelenota anax, and other species of family Stichopodidae are also called gamat. The same commercial name is used by the Sabah and Sarawak residents in East Malaysia. In fact, there are different definitions of gamat from previous studies in Malaysia (i.e. from 1985 until June 2011), and the most appropriate definition is that gamat is exclusively referred to the sea cucumbers of family Stichopodidae, as mentioned above.

In Sabah, East Malaysia the sea cucumbers inclusive of gamat are commercially marketed as food, and there are minor uses as fishing poison (e.g. holothurins from Holothuria atra) and in the traditional medication. Approximately 155 tonnes of sea cucumbers were landed in 1995 as estimated by the Sabah Fisheries Department. However, the use of sea cucumbers in Sarawak, East Malaysia is not well documented and the information on the species presence and distribution is sparse. It was reported by Hashim (1993) that the Sarawak fishermen used brunok (Acaudina molpadioides (Semper, 1867)) as fishing bait.
Basically, there are 2 main economic practices of sea cucumbers in Malaysia: an important source of traditional medicine (i.e. gamat lipid extracts and gamat water extracts) as well as modern medicine in Peninsular Malaysia, West Malaysia and an important source in the food industry in Sabah, East Malaysia.
Several studies related to sea cucumbers (Echinodermata: Holothuroidea) in Malaysia have been published since 1985. The earliest study documented in Malaysia on the distribution of sea cucumbers using morphological characteristics was conducted by Ridzwan Hashim (Professor of International Islamic University Malaysia) and Che Bashah Che Chat in 1985. In fact, molecular approaches are capable of providing insights into the phylogeny of sea cucumbers and can support the outcomes of traditional morphological approaches, and a number of molecular ecological studies have also been recorded in Malaysia since 1999.
