Species Introduction

Chinese name: Leopard print rays (pinyin: bào wén hóng);

English name: Reticulate whipray;

Scientific name: Himantura uarnak.

Leopard print ray, also known as yellow line narrow tail, has a maximum recording width of 2 meters, a total length of 6 meters, and a weight of 120 kg. It is distributed in the Indo-Western Pacific region, starting from Red Sea and the eastern Mediterranean Sea (via Suez Canal ) in the west to southern Africa, reaching French Polynesia in the east, to Taiwan in the north, and to Australia in the south. Generally, most of them are active in the sandy and mud-bottomed sea areas along the coast, feeding on benthic shrimps and crabs, worms, and jellyfish. Tail spikes have toxic glands and are dangerous marine organisms .

appearance characteristics Description

Leopard print rays with a maximum recording width of 2 meters, a total length of 6 meters, and a weight of 120 kg. The body disk is rhombus, with a slightly concave leading edge, and is 60 degrees from the snout; the body disk width is about 1.1-1.2 times longer than the body disk, and the widest is in the middle of the body disk. The kiss is quite pointed and protruding; the length of the kiss is equal to 1/4 of the length of the body plate, about twice the distance between the eyes. The eyes are quite small and slightly protruding, and the eye diameter is about a little smaller than the water spray hole. The mouth is small, and the length of the kiss in front of the mouth is 2.5-2.7 times larger than the mouth.

333best3, 4-7 mastoids, the left and right of the middle 3 are the most obvious, and the mastoid processes in the center are small or disappear; the two on the outermost side are small but small, while the two on the inner side are small or disappear. The tail is slender, three times the length of the body plate; the skin folds on the dorsal and ventral sides completely disappear; 1 tail spike. There is a small group of conical small spines in the center of the dorsal dorsum from the gill area to the shoulder strap area, with a large line in the center and yellow; the small spines of adult fish are divided and expanded, and even spines are present at the entire tail. The back of the young fish is white and covered with black dots, which gradually turns gray as it grows, but it is still covered with black dots. The adult fish is light brown, and the black dots expand into leopard pattern spots or cloud-like spots; the ventral surface is pale and brown in the border area; the tail has a black and white color ring that extends to the end of the tail. Dasyatis uarnak is the same name of this species.

Ecological habits Ecological Habit

Leopard print ray is a benthic fish and is one of the largest stingray . Generally, most of them are active in the sandy and mud-bottomed waters along the coast, and often enter the estuary area or the shallower lagoon area with orgasm, and can even be found in the sandy and mud-bottoms in the coral reef area. The activity depth is between 5-50 meters. When he lies out at night, he often burys his body in the sand, revealing only his eyes and breathing holes, waiting for an opportunity to prey on small fish, benthic shrimps and crabs, worms and jellyfish. Tail spikes have toxic glands and are dangerous marine organisms.

Growth and Breed

Leopard rays are viviparous and reproduced in summer, producing 3-5 young fish each time, and the gestation period lasts for 1 year.

Geographical distribution Distribution

Leopard print rays are distributed in the Indo-Western Pacific region, starting from the Red Sea and the eastern Mediterranean Sea in the west (via the Suez Canal) to southern Africa, reaching French Polynesia in the east, to Taiwan in the north, and to Australia in the south.
