General Description

Body robust, somewhat oval, brown to greyish on top, white below, covered in long white to yellow spines and 3-4 dark vertical bands or blotches on sides. The spines usually lay flat against the body. When threatened, globefish rapidly inflate themselves with water or air, causing the spines to stand erect. To 30 cm, although most grow to about 15 cm.

Biology

When threatened, Globefish greatly inflate their bodies causing their spines to stand erect from the body and becoming spiny "globes".
