The eyes of the nocturnal Vanadis bristle worm are so enormous that they would add an extra 100 kg to the skull of a human if human eyes were that size.
Researchers have recently found that these enormous eyes have a high sensitivity to ultraviolet (UV) light, which means they could be utilized for covert communication in the dark of the ocean.
Their large eyes function similarly to our eyes and are likewise well developed. This type of eye is unique to humans; other animals such as insects, spiders, octopi, and squid do not possess it.
One of the marine biologists who studied the worm’s extraordinary eyes, Michael Bok from Lund University, noted that it is actually rather unusual to be able to see in enough depth and at a high enough frame rate to be able to distinguish certain objects.
