Potamotrygon castexi
Jaguar Stingray
豹魟
Otorongo Ray (also known as "Jaguar" Ray, P25, P26, P28 or P35): This popular variant has a covering of light-coloured spots that are quite widely spaced around the edges of the disc, becoming less well-defined and much closer together towards the centre. In some specimens they appear as a single mass in the centre of the fish. 
Tigrinus Ray (also known as "Tigrillo" Ray, P30, P31 or P32, ): This one looks quite similar to the Otorongo variant but the spots towards the centre of the disc are fused together, resulting in a lattice-like pattern. 
Motelo Ray (also know as "Tortoise" Ray or P36): Again similar to the Otorongo fish, but so named because the spots on the disc are arranged in small groups, resulting in a pattern not unlike that seen on the shell of a tortoise. 
Estrella Ray (also known as "Star" Ray, P33 or P34): Here the spots are much less in number, giving an appearance reminiscent of a starry night sky (you might need to squint a bit!). In the centre of the disc the spots may appear in small clusters. 
Carpet Ray or P54: This form has a dense patterning of small spots and broken circles. 
豹魟属于大型的南美魟鱼,在纹路、色彩表现上有相当大的变化,产地的变异个体繁多,在市场上很受欢迎,如绿豆魟、金点豹魟、金玉满堂、满天星、龟甲满天星。等都是属豹魟因色彩斑纹差异而命的俗名。豹魟的分布广泛,在整个亚马逊和流域都可以发现它的踪迹,不同的环境下,很容易产生色彩纹路的变异,加上个体间的杂交,因此难以用花色区别分类。基本上豹魟身上的斑纹多为大小不一的金色远点、不规则的小斑点、龟甲般的纹路、等,今年来东南亚地区运用人工配种繁殖方式培育出许多纹路特殊少见的新品系,以满足玩家们的需求。
豹魟的个性活泼好动,体格强健,具侵略性,常会欺负其他混养的鱼类。对水质适应力强,对食物不挑剔,小鱼、虾、泥鳅、红虫都可以接受。
