New Fish Species 'Rogadius Azizahae' Discovered In Malaysian Waters
Subscribe to our FREE We have a new fish species in the waters of the South China Sea! The ''Rogadius azizahae' fish was discovered by Dr Tun Nurul Aimi Mat Jaafar of Universiti Malaysia Terengganu's (UMT) Faculty of Fisheries and Aquaculture Sciences. It was found off the coasts of Terengganu and Johor during a scientific expedition on demersal fisheries resources in the east coast exclusive economic zone on 5 and 30 June 2016. Three specimens of the fish were discovered at depths between 53 and 58 metres.

Zootaxa validated the species' name prior to its publication in the Rogadius azizahae, or its local name Baji Azizah, is a small-sized fish measuring between 10 and 11 cm long. It's a bottom-dwelling fish. Coupled with its flat body shape and brownish colouration with translucent white centre, the fish is adept at camouflage, skillfully blending with the deep-sea sand. The scientific name ''azizahae'' was chosen as a tribute to Prof Dr Siti Azizah Mohd Nor, UMT's Senior Research Fellow, in recognition of her significant contributions to the field of molecular ecology and the conservation of fish biodiversity in Malaysia. Nurul Aimi shared that the discovery is evidence that Malaysian waters, especially the South China Sea, is rich in untapped biodiversity still waiting to be explored. The discovery additionally opens up opportunities to study benthic fish community in Malaysian waters, which remains largely unexplored. It also provides the university a platform to strengthen marine conservation efforts, deepen understanding of marine ecosystems, and support the enhancement of national fisheries resource management policies.

A demersal fish is also known as a groundfish and they live and feed on or near the bottom of seas or lakes (the demersal zone). Demersal fish is divided into two main types: the benthic and the benthopelagic fish. Benthic fish can rest on the sea floor while benthopelagic fish can float in the water column just above the sea floor. In terms of buoyancy, benthic fish is denser which makes it easier for these fish to lie on the sea floor without any efoort. Meanwhile, benthopelagic fish have neutral buoyancy which gives them an ability to float at depth without much effort. Examples of benthic fish include halibut, flounder, turbot, sole, and plaice.

'Rogadius azizahae': UMT researcher discovers new fish species in Malaysian waters
KUALA NERUS: A researcher from Universiti Malaysia Terengganu (UMT) has discovered a new fish species, 'Rogadius azizahae', in the waters of the South China Sea, marking a significant addition to Malaysia's rich marine biodiversity. Dr Tun Nurul Aimi Mat Jaafar, from UMT's Faculty of Fisheries and Aquaculture Sciences, said that the unique species was discovered on June 5 and 30, 2016, off the coasts of Terengganu and Johor, during a scientific expedition on demersal fisheries resources in the east coast exclusive economic zone, conducted in collaboration with the Fisheries Department. She said that the fish species, which belongs to the flathead family, has been officially recognised by Zootaxa, an international taxonomic authority, which validated the species' name prior to its publication in the Journal of Fish Biology on Aug 4, 2025. "These three specimens were discovered at depths of between 53 and 58 metres, during a scientific expedition involving UMT researchers, officers from the Fisheries Department, and students," she added. "Rogadius azizahae, or its local name Baji Azizah, is a small-sized fish measuring between 10 and 11 centimetres in length. "It features a fine dark pattern on its pelvic fins and a translucent white centre," she said at a press conference at UMT yesterday today. She said that Baji Azizah is a species of bottom-dwelling fish, which is difficult to detect due to its flat body shape and brownish colouration, which closely resembles the seabed. These features make the species highly adept at natural camouflage, allowing it to blend seamlessly into the deep-sea sand. She said the discovery is proof that Malaysian waters, particularly the South China Sea, remain rich in untapped biodiversity, with many marine treasures still waiting to be explored for the benefit of humanity. "This opens up vast opportunities for further research into the benthic fish community in Malaysian waters, which remains largely unexplored. "In fact, it also provides a platform for UMT to strengthen marine conservation efforts, deepen understanding of marine ecosystems, and support the enhancement of national fisheries resource management policies. She said that the scientific name 'azizahae' was chosen as a tribute to Prof Dr Siti Azizah Mohd Nor, UMT's Senior Research Fellow, in recognition of her significant contributions to the field of molecular ecology and the conservation of fish biodiversity in Malaysia. Meanwhile, Siti Azizah, who was also present at the press conference, said that further research would be conducted to better understand the characteristics and ecological significance of the newly discovered species. "We still don't know the full details about this fish, but it is important to conserve all aquatic species to protect the richness of marine biodiversity. "A higher level of biodiversity in an ecosystem increases its resilience, which is especially crucial in the face of global climate change, as it affects both marine life and humans," she said. – Bernama

New fish species named Rogadius Azizahae after Professor Dr Siti Azizah
A TEAM from Universiti Malaysia Terengganu (UMT) has identified a new species of fish, Rogadius azizahae, found in the South China Sea, marking a significant milestone in marine biodiversity research. Dr Tun Nurul Aimi Mat Jaafar, from UMT's Faculty of Fisheries and Aquaculture Sciences, shared that the discovery took place during a scientific expedition in June 2016, conducted in collaboration with the Department of Fisheries Malaysia. The team collected specimens off the coasts of Terengganu and Johor as part of the Demersal Fisheries Resources Scientific Expedition within Malaysia's Eastern Exclusive Economic Zone. The newly discovered species, which belongs to the flathead family, was later formally recognised by Zootaxa, an international authority on taxonomy. It was officially documented in the Journal of Fish Biology on 4 August 2025. 'These three specimens were found at depths between 53 and 58 metres during the scientific expedition involving UMT researchers, Department of Fisheries officers, and students,' Dr Tun Nurul Aimi said during a press briefing at UMT. Commonly referred to as Baji Azizah, the fish is relatively small—only about 10 to 11 centimetres in length—and features distinctive dark markings on its pelvic fins, with a semi-translucent white midsection. According to Dr Tun, the fish's flat body and brownish hue enable it to blend seamlessly with the ocean floor, making it extremely challenging to spot. 'These traits allow the species to camouflage naturally by blending into the deep-sea sand,' she explained. She added that this find underscores the untapped biodiversity within Malaysian waters, particularly in the South China Sea. 'This opens vast opportunities for further research into deep-sea fish communities in Malaysian waters that have yet to be fully explored,' she said. 'In fact, it also paves the way for UMT to strengthen conservation efforts, enhance understanding of marine ecosystems, and reinforce national fisheries resource management policies.' The species name azizahae was chosen in honour of UMT's senior research fellow, Professor Dr Siti Azizah Mohd Nor, who has made impactful contributions to molecular ecology and fish biodiversity conservation in Malaysia. Prof Siti Azizah, who was also present at the press conference, noted that more in-depth studies are planned to better understand the ecological role and characteristics of the species. 'We still don't know the detailed traits of this fish, but every species and marine life must be protected to ensure the richness of marine biodiversity,' she said. 'A higher biodiversity within an ecosystem is better as it increases resilience, especially in facing global climate change issues that affect both wildlife and humanity,' she added. —Aug 6, 2025 Main image: Bernama
