Identifying features

​Globefish have an oval shaped body covered in spines that usually lie flat except near the tail. They are a greenish blue colour on the back and white underneath with yellow to green fins. They will inflate themselves with air or water on capture causing the spines to stand out from the body as a defensive weapon against predators.


Globefish are normally solitary in Tasmania, preferring shallow seagrass beds and sandy bottom down to 50 metres. They will occasionally venture out over reefs in search of food.

Fishing information

These fish are poisonous. They are not targeted by recreational fishers, rather usually an unwanted bycatch that take baits and lures destined for other species. If small hooks are used, it is likely any catching of a globefish will result in gut hooking. Being larger than other toad fish, they will tend to give an indication of a slow bite on rod and line though often after they have consumed your bait and hook.


There should be no reason to retain this fish at all because it is poisonous to eat and covered with sharp pointed spines. If their spines are inflated, handle very carefully or preferably not at all.


Poisonous. Do not eat.
