This large weed whiting is common in seagrass meadows, where it is often found in large groups. Females are a patchy green colour, often with a dark mid-body stripe, while males are a blueish green. Both sexes often have a white dorsal stripe. They can be easily confused with the Little Weed Whiting (Neoodax balteatus), particularly females, but they can be distinguished by their larger size and longer snout.
