AppearanceGuineafowl puffers have heavy rounded bodies that are uniformly black with numerous small white spots, bright yellow spots or a mixture of the two morphologies with bright yellow spots and black patches.
They have large blunt heads with short snouts and are equipped with a set of massive teeth. They have small and similarly shaped anal and dorsal fins that are well back on their body. Their caudal fin base is long and deep and their caudal fin is rounded.
Their body is covered with small denticles that resemble coarse sandpaper. When this fish is scared or frightened in any way, they shrink and make themselves the least noticeable as possible. They often lurk in shadows in order to not be seen.
