Indian Walkman
Scientific name Synodus indicus
The Indian Walkman — more accurately known as the Indian Lizardfish — is a well-camouflaged ambush predator commonly found resting on sandy seabeds. Its elongated body, large mouth filled with sharp teeth and mottled brown patterning allow it to blend almost perfectly with sand and rubble. Around Koh Tao, they are frequently seen lying motionless on open sand between 5–30 metres, often near reef edges or rubble zones. At first glance, they may look like part of the seabed until they suddenly dart forward to strike prey. Despite the nickname “Walkman,” they don’t actually walk — they rest on their pelvic fins and use short bursts of speed to ambush small fish. They are generally calm around divers and rely heavily on camouflage rather than fleeing.

Divemaster's tip
Scan sandy patches carefully — look for a pair of eyes and a slightly raised head. Approach slowly from the side rather than directly above to avoid startling them.
What do they eat?
Indian Lizardfish feed mainly on small fish and crustaceans. They rely on stillness and lightning-fast lunges to capture prey, playing the role of stealth predator in Koh Tao’s sandy reef habitats.
