Newly Discovered “Hybrid” Eye Cell Challenges 150 Years of Biology

A newly discovered visual cell in deep-sea fish larvae is reshaping long-held assumptions about how vertebrates see the world. Down in the ocean’s “twilight zone,” sunlight fades fast. Colors disappear, shadows soften, and even small improvements in sensitivity can mean the difference between finding food and going hungry. Now, researchers say deep-sea fish larvae have [...]

How does the new hybrid eye cell change vision science?

A hybrid photoreceptor upends a century‑old idea about vertebrate sight Scientists have identified a previously unknown type of visual cell in the larvae of deep‑sea fish that blends features long associated with two distinct photoreceptor classes. That finding matters because it challenges the…
