Silver Tripodfish

Interesting Info

• The Silver Tripodfish is a rare shallow-water tripodfish from the Indo-West Pacific, recognised for its gleaming silvery body and sharp spines.
• It belongs to the family Triacanthidae, the true tripodfishes, which are different from the deep-sea “tripod spiderfishes” that balance on extra-long fin rays.
• In Australia, the Silver Tripodfish lives off the northwest coast between Broome Western Australia and the Northern Territory.
• Its body is oval and laterally compressed, covered with smooth silvery scales that reflect light, making it appear bright underwater.
• The dorsal fin carries two strong spines, while the pelvic fins form a stout spine that acts like a prop, helping the fish steady itself on sandy bottoms.
• This “tripod” stance is how the group earned its name, as the fish can brace itself on the seabed using its fin spines.
• The Silver Tripodfish feeds on worms, small molluscs, and crustaceans that it digs out of soft sediment with its small mouth.
• It inhabits shallow sandy or muddy areas near reefs, lagoons, and coastal bays, usually at depths of 10–50 m (33–165 ft) but up to 200 m.
• Juveniles often appear in lagoons or estuaries, where they take shelter among algae, rubble, or seagrass beds.
• This species is sometimes confused with the Shortnose Tripodfish, but it is slimmer and more silvery in colour, with a less blunt snout.
• It is sometimes caught as bycatch in small-scale coastal fisheries, but has no commercial importance.
• The flesh is edible, but because it is small and bony, it is not a valued food fish.
• The scientific name nieuhofi honours Dutch naturalist Jacob Nieuhof, who travelled widely in the East Indies during the 1600s.
