Simple strokes of pufferfish pictures
Pufferfish, commonly known as "pufferfish", is the collective name for fish in the family Pufferidae, a bony fish.
The body of pufferfish is cylindrical and has air bags. It will inhale and expand when it encounters danger. The body length is generally about 100 to 300mm, and the large ones can reach more than 630mm. The upper and lower jaw bones and teeth fuse together to form four large dental plates, with a body length of up to 1.1M. 1 dorsal fin, no pelvic fin. Scaleless or with small spines. Overall oval shape, bluntly rounded at the front and tapering at the tail. The snout is short, round and blunt; the mouth is small, terminal, and transversely cleft. There are two plate-shaped incisors in the upper and lower jaws respectively, with an obvious middle suture. The lips are well developed, with both ends of the lower lip curving upward on the outside of the upper lip. The eyes are small, the gill opening is small, and it is an arc-shaped slit in front of the pectoral fins. The body surface is densely covered with small spines. The dorsal fin is located very far back, opposite to the anal fin; there is no pelvic fin; the rear end of the caudal fin is truncated. The back of the body is grey-brown, the sides are slightly yellowish-brown, and the belly is white; the markings on the back and sides of the body vary with the species. There are many species, most of which live in the sea, but they can also be found in fresh water and the confluence of sea and fresh water. They blow water and air through the water, causing the sand to fly up, and then prey on creatures hiding in the sand. The teeth and jaws are very strong and can crush extremely hard shells.
