簡介

把自己當成沙灘毯，鰭一揮就蓋上一層沙，連潛水員來掀沙都只是微微不爽。

Treats the seabed as a beach blanket: one flap of the fins and it's covered in sand, and even a diver wafting it away only mildly annoys it.

小知識

盤寬可達 1 公尺以上，一胎 2–8 隻，初生就約 18 公分寬。尾巴有帶毒腺的小刺。因拖網混獲，中國大陸沿岸部分族群已減少多達 95%，被列為易危。日本千葉和伊豆潛點相對常見。

Disc over 1 m wide; 2–8 pups per litter, each about 18 cm across. Its small tail spine has venom glands. Bycatch has cut some mainland Asian populations by up to 95%, so it is listed Vulnerable. Fairly common at Chiba and Izu dive sites.
