Longray Weed Whiting

Interesting Info

• The Longray Weed Whiting is a slender seagrass-dwelling fish found only in southern Australia, from Perth in Western Australia across South Australia and Victoria, and around Tasmania.
• It belongs to the odacid family, a small group of fishes unique to southern Australia and New Zealand that live closely tied to seagrass meadows and algal beds.
• The name “Longray” comes from its extended fin rays, which trail behind the dorsal and anal fins, giving it a distinctive outline.
• Its body is narrow and pencil-like, coloured brownish to olive green with faint striping, blending perfectly among seagrass blades.
• Juveniles are tiny and even more translucent, making them almost invisible among shallow weed beds close to shore.
• Longray Weed Whitings live in shallow coastal waters from the surface down to 20 m (65 ft), usually sticking close to seagrass and algal cover.
• They feed on small crustaceans, worms, and bits of algae, which they pick delicately from seagrass blades with their pointed snouts.
• Predators include larger reef fish, squid, and wading birds that forage in seagrass meadows.
• Spawning is thought to occur in warmer months, with eggs released into the water column to drift until hatching.
• The lifespan is not precisely known but is likely 5–6 years, similar to related weed whiting species.
• They play an important ecological role as grazers and prey, linking seagrass invertebrates to larger predators higher in the food chain.
