The Wavy Grubfish (Parapercis haackei) belongs to the Grubfishes family Pinguipedidae. Grubfishes are long elongate species with long dorsal and anal fins and large bulging eyes placed high on head. They are usually found resting on the substrate perched up with their very strong pectoral fins. They can be a curious fish species and will often investigate divers if they stir the bottom. There are about 20 species found in Australian waters with the majority of species being found in the warmer tropical waters.
The Wavy Grubfish can be identified by the dusky/brown band that runs from behind the eye along the entire length of the body to the base of the caudal fin. This band can become quite wavy in the adults and this is where (Parapercis haackei) got its common name from. This species can be found in shallow coastal estuaries and bays and can be common underneath jetties where it moves about the rubble. This species grows to a maximum length of approximately 15cm.
