Anglerfish (5)

Sample: the big ones can reach 1-1.5 meters. There are three kinds in our country, - a kind of yellow monkfish, another kind of black monkfish, and a newly discovered kind of monkfish called sun monkfish. Big mouth with two rows of hard teeth, very ugly appearance, general body length 40 ~ 60 cm, weight 300 ~ 800 grams. The former has more than 2 rows of teeth in the lower jaw. Inside the mouth is white, with skin folds sticking out in front, and 8-11 brachial fins; the latter has 3 rows of mandibular teeth, black and white rounded spots inside the mouth, and 6-7 brachial fins. The monkfish is good at camouflage and hard to detect, and its body is thinly pointed backward to become a columnar shape. The head is large, and when viewed from above, the body is soft and scaleless, with a brownish dorsal surface that resembles a handled skillet. The anterior most spines of the dorsal fin are elongated like a fishing rod, with skin folds sticking out of the front end, which looks very much like a lure. The head is particularly large and flat, with a wide mouth, a short ventral fin, and a rounded, truncated caudal fin. The anglerfish has two dorsal fins, the first of which is different from that of ordinary fish, and is composed of five to six independently detached fin spines. The anglerfish uses this bait-like shape to wiggle and lure its prey before swallowing it in one big gulp. The pectoral fins are so developed that they can move across the seafloor like feet. [2]?
