The puffer’s eyes can move independently of each other. But more importantly, it provides sharper vision than most other fish possess-an important survival strategy that allows the puffer to identify potential threats from farther away.

#CUTE PUFFER FISH CRACK#
The pufferfish diet is made up primarily of invertebrates and algae, and larger fish can sometimes be seen using their hard beaks to crack open clams, mussels and other shellfish.Īll puffers have snouts with four large teeth fused into an upper and lower plate, which are used for crushing the shells of crustaceans and mollusks. All puffers have snouts with four large teeth fused into an upper and lower plate, which are used for crushing the shells of crustaceans and mollusks. Some sport bold markings and colors to advertise their toxicity, while others have more muted or cryptic coloring to blend in with their environment. They are scaleless fish and usually have rough to spiky skin. They come in a wide range of sizes, from the dwarf puffer, which is often less than an inch (2.5 cm) in length, to the starry puffer, which grows up to four feet (1.3 meters).
