The marine iguana is in truth only to be found thriving within the Galapagos Islands that is why its existence in the island has branded the reptile the name “Galapagos marine iguana”. The natural habitat of the marine iguana is on the rocky shores of the Galapagos Island but they can likewise be seen in the mangrove and marshes beaches.

Charles Darwin described the marine iguana as the black lizards thriving on the sea. But the truth is that the marine iguanas are not usually black in color. The younger marine iguanas take the dorsal stripe color whereas the adult ones are grayish. Their color may be really dull but there is a reason behind this. Such color allows them to easily absorb heat right after they emerge out of the water. The salt contained in their bodies makes their faces appear whiter.

More so, the matured male marine iguanas have a varying color—all of which depend on the existing season. During the breeding seasons, the adult male marine iguanas become teal-green or reddish in colors. Those thriving in Santa Cruz appear in black and red brick while those found in Fernandina come in dull green and brick red colors. Their sizes likewise differ which depends on the island that they live in. Those found in the whole of Isabela and Fernandina are the largest marine iguanas in the entire island of Galapagos. Meanwhile, the smallest marine iguanas are to be found in Genovesa.

To date, the government of Ecuador has set up laws that aim to protect the existence of marine iguanas. There are artificial nestling sites which had been made in the smaller islands so that there will be lesser predators that can harm them.

These are beautiful reptiles and should be saved - if nothing but to preserve history….

Though my question would be, what is the significance of “naturally selecting” the color pink in the species?

I can’t think of many animals out there that are that particular color, other than the Pink Panther, that is.
