We Still Don't Know Why These Lizards Have Lime-Green Blood

The prehensile tailed skink from the highlands of New Papua New Guinea has green blood due to high concentrations of the green bile pigment biliverdin. The green bile pigment in the blood overwhelms the intense crimson color of red blood cells resulting

"In addition to having the highest concentration of biliverdin recorded for any animal, these lizards have somehow evolved a resistance to bile pigment toxicity", Zachary Rodriguez, a biologist from Louisiana State University (LSU), said in a statement. You might have heard of the substance, as it's present in our organism as bile pigment.

The lizards are skinks, members of the very diverse Scincadae family. It turned out that numerous species with green blood aren't closely related to one another, and have more in common phylogenetically with red-blooded skinks. A new investigation, published online today (May 16) in the journal Science Advances, finds that skinks likely evolved to have green blood a total of four different times throughout history, suggesting that this trait is evolutionarily advantageous.

There are several lizard species in New Guinea with green blood, instead of the usual red.

High levels of biliverdin cause jaundice in most animals, but these lizards thrive despite biliverdin levels many times greater than the lethal concentration in people.

So Austin, Perkins, and their colleague Zachary Rodriguez made a decision to create a kind of lizard family tree by studying the DNA of 51 Australasian skink species, including six species that have green blood.

Why do the odd lizards have green blood? The excess of green bile pigment essentially eclipses the normal ruddy hue of their red blood cells. "Ongoing work with the Austin lab examines the potential effect of the green blood pigment on malaria and other parasites that infect these lizards", said co-author Susan Perkins, curator and professor at the Sackler Institute for Comparative Genomics and the Division of Invertebrate Zoology, American Museum of Natural History.

"Our next goal is to identify the genes responsible for green blood", Rodriguez said. Now, a genomic analysis of the lizards reveals this remarkable physiology may have arisen in the group four separate times in their evolutionary history. "The problem is that there's green-blooded lizards that aren't green, and there's red-blooded lizards that are green", he explains. Slightly elevated levels of bile pigments in other animals, including insects, fish and frogs, have played potentially positive roles in these animals. Multiple origins of green blood in New Guinea lizards. This suggests that green blood might have been an adaptive reaction, but researchers can not tell why the process had occurred.
