Mudskipper (certain introduction)
Mudskipper is a small, warm-temperature fish along the coast. Fish, they will use their pelvic fins to crawl and jump on the beach or soil, but after being slightly startled by a sound, they will jump back into the water or drill into a hole. Mudskippers like to live alone. They can rely on their skin and tail to help them breathe, so they can stay on the shore longer.
The mudskipper has an extended body, flat sides, and a large, nearly cylindrical head. Generally, the body length is 10 to 20 meters and the body weight is 20 to 50 grams. The eyes are set high, close to each other and above the top of the head, and the lower eyelids are well developed. The mouth is roughly slanted, and the two jaws are equal in length. Each jaw has 1 row of teeth. The maxillary teeth are cone-shaped, and the 3 teeth on each side of the front line are canine-shaped; the mandibular teeth are slanted outward and almost recumbent. The body is covered with small round scales and no lateral lines. The base of the pectoral fin is extended, the muscular stalk is developed, and the pelvic fin heals into a sucker. The body is dark brown, with small blue dots on the dorsal and caudal fins. The back of the body is dark brown. Abdomen gray. There are 6 black strips on the back, irregular green-brown freckles all over the body, and two dorsal fins. The first dorsal fin is very small. There are only 5 fin spines, and the fin spines end up extending in filaments, of which the third spine is the longest; the second dorsal fin and anal fin are both longer, and their length is about 10%. The caudal fin is wedge-shaped and round, the second dorsal fin has three regular gray-white horizontal lines, and the pectoral fin has a yellow-green insect pattern, which is particularly beautiful.
