为什么怀特塞德被称为“白边”

怀特塞德，是一种淡水鱼类，因其身体两侧有一条白色的细边而得名。它的学名是Pteronotropis hypselopterus，属于脂鲤科。怀特塞德生活在北美洲的流域中，包括密西西比河、密苏里河、奥黑奇河等地。由于其身上的白边，怀特塞德在民间被称为“白边”。

怀特塞德的生活习性

怀特塞德是一种淡水鱼类，主要生活在水流较缓慢的河流和湖泊中。它们喜欢栖息在水草丛中或者树枝下面，用来躲避天敌和捕食猎物。怀特塞德是一种群居鱼类，它们经常聚集在一起游动，一旦发现食物就会快速地向食物聚集。怀特塞德的食性比较杂，主要以小型无脊椎动物为食，包括昆虫、甲壳类动物、软体动物等。

怀特塞德的数量骤减

在过去几十年中，怀特塞德的数量骤减。这主要是由于人类活动对怀特塞德生存环境的破坏造成的。大量的污染物、工业废水和农业化肥流入河流和湖泊中，破坏了怀特塞德的栖息环境，导致其数量锐减。此外，过度的捕捞也是怀特塞德数量减少的原因之一。怀特塞德是一种很受欢迎的观赏鱼类，而且肉质鲜美，被用来作为食物。大量的捕捞导致怀特塞德数量锐减，有些地区已经濒临灭绝。
