Komodo dragons have teeth capped with a layer of iron

The Facts
Scientists have found a "striking" and "predatory adaptation" in the Komodo dragon: a layer of iron coating on its teeth, keeping its "serrated edges razor sharp."
According to a paper published Wednesday in Nature Ecology & Evolution, iron in the cutting edge and tips of the world's largest lizard species' teeth stain them orange.
The Spin
Narrative A
The Komodo dragon faces a grim future due to climate change and human activity. With just over 1.3K mature dragons left, their Indonesian habitat is shrinking rapidly due to rising sea levels and agricultural expansion. Decision-making is urgently needed to preserve this iconic species.
Narrative B
The Komodo dragon has survived for millions of years because it requires little energy and can tolerate harsh environments. Therefore, the reptile’s endangered status — based on habitat loss due to rising temperatures and sea levels associated with climate change — should be reassessed.
