求专家鉴定：哪种鳅？ [12P]

<p>3.27下班回后海家路过官园淘的，从没见过的鳅。图片规格：900×506</p><p>&nbsp;</p><p>&nbsp;</p><img src="attachments/dvbbs/2008-3/20083288432793924.jpg" border="0" onclick="zoom(this)" onload="if(this.width>document.body.clientWidth*0.5) {this.resized=true;this.width=document.body.clientWidth*0.5;this.style.cursor='pointer';} else {this.onclick=null}" alt="" /><br/><img src="attachments/dvbbs/2008-3/20083288433462404.jpg" border="0" onclick="zoom(this)" onload="if(this.width>document.body.clientWidth*0.5) {this.resized=true;this.width=document.body.clientWidth*0.5;this.style.cursor='pointer';} else {this.onclick=null}" alt="" /><br/><img src="attachments/dvbbs/2008-3/20083288434258064.jpg" border="0" onclick="zoom(this)" onload="if(this.width>document.body.clientWidth*0.5) {this.resized=true;this.width=document.body.clientWidth*0.5;this.style.cursor='pointer';} else {this.onclick=null}" alt="" /><br/>

楼主是广东的？？？？？

<p>呵呵,我记的楼主是北京的吧...</p><p>北京是没有平头岭鳅的,这一点很重要,排除了这一点,只能是北鳅.</p><p>二者从感官上不好分辨,说实话我也很模糊....二者属不同,可见基因差异比较大,北鳅在北方很常见,我也有饲养过,但平头岭无分布,所以无法说出其具体差异...内部器官构造不详......</p><p>硬要说的话,个人意见二者还是有不同点的,北鳅背鳍的起点于腹鳍正上方稍稍靠后一些,而平头岭则靠后的位置大些,前部侧线鳞明显(个人感觉)..</p><p>等各位大大的高见</p>

我看到了青鳉[em02]
