This ancestor was probably a predatory marine fish with good eyesight, jaws and teeth, and a lateral line system for detecting water movements, visible as a stripe along the flank of most current fish such as sharks that have such a sixth sense.

这种祖先很可能是一种捕食性海洋鱼类,拥有出众的视力、双颚和牙齿。其用于感知水流变化的侧线系统看起来就是体侧的一条纹路,如今包括鲨鱼在内的大多鱼类都有,起到第六感的功能。 |
