The body is in shape, longer than most other triggers with long narrow hind legs. Its maximum size is 50 cm in length.


Abalistes stellatus live mainly in clay and mud. However, sloping areas often have distances above the surface.  Usually found in domestic banks. Adults can be found in estuaries, and young species protect the lives of their parents. Through these diverse habitats, adults reach a depth of 7 to 350.


Abalistes stellatus is about 60 cm long. It has 25-27 spines (including spikes) and 24-25 rays of the anus. His body is dark gray, turned into olives, and covered with small white spots


Most are lonely, but they do mate when they multiply. Females lay their eggs on the ground. These products include crustaceans, mollusks, and echinoderms.


This is oviparous species lay an egg then male species produce sperm to water. In these fishes, external fertilization is found. Ejaculation of sperm fertilizes the egg.[1]A new triggerfish of the genus Abalistes (Tetraodontiformes: Balistidae) from the western Pacific – The Australian Museum[2]Tan2019Singap._Biodivers._Rec.pdf ([3]Abalistes stellatus – Wikipedia
