Amblyopsidae (1077 words) |
 | One of the facts that has been very controversial about the phylogeny of this order is that they show primitive conditions such as the presence of an adipose fin, which suggests character reversal in their evolutionary history. |
| The Amblyopsidae is a freshwater family distributed in the southern and eastern (unglaciated) United States (Figure 1). |
| They are characterized by having a large, flattened head, oblique mouth, strongly protruding lower jaw, large branchial cavity (probably for oral incubation), a jugular vent (anus), and small embedded cycloid scales, except in the head which is naked. |
