It is believed that the coelacanths and lungfish represent a crucial link between other fishes and tetrapods. What is the major feature in these fish in support of this hypothesis? Like amphibians, they are tied to the water for reproduction. Their fins have skeletal and muscular structures similar to amphibian limbs. They have lungs and are able to breathe air when water is scarce. O They have highly evolved nervous and circulatory systems. O They enter a hibernative stage when food is scarce, as many tetrapods do.
