Critical Thinking - Question 1
Hagfishes and lampreys are the only living representatives of a very ancient group. Why do you suppose there are still some of these jawless fishes around?
I suppose hagfishes and lampreys (jawless fishes) are still living today because of the simplicity of their way of life. Hagfishes feed mostly on dead or dying fishes while lampreys attach to other fishes and suck their blood or feed on bottom invertebrates. Both jawless fishes do not require much effort for survival.
