The water-to-land transition occurred independently several times in the protostomes. What is not an example of an adaptation for terrestrial living that may have arisen by convergent evolution?

Decreased surface to volume ratios to increase the efficiency of the gas exchange in air

Explanation:

The protostomes are coelomate invertebrates in which the mouth is been formed firstly from an opening called the blastopore. They are arthropods, mollusks, and annelids.The important difference between protostomes and deuterostomes is between the point of the blastopore. In protostomes, the blastopore is been developed into the mouth, and the opposite cavity develops into the anus. While In deuterostomes (the group that includes echinoderms and vertebrates ), the blastopore in been developed into the anus.
