Sharks are terrible creatures On The best time And whale sharks – despite being harmless to humans – are the largest of all, given that they can grow up to 32 feet. But scientists have revealed a whole new layer of wonder (and possibly terror) about the biggest fish in the ocean.

Their eyes are covered with teeth.

The technical term is “dermal denticles”.

Dermal dentin is essentially small structures that look and feel similar to scales, but are actually teeth. Shark skin is also made of dermal teeth with its rough, sandpaper-like texture. These cutaneous dentures actually help reduce friction in water, enabling sharks to swim faster.

But despite the fact sharks include them on dermal dentistry Literal eyeball Is very unique. Scientists at the Okinawa Churashima Research Center in Japan, who were the authors of the study, say it is “a novel mechanism of eye protection in vertebrates”. The teeth are slightly different from those found on shark’s skin, as they are designed for “abrasion resistance”. Essentially these teeth are designed to help protect the eyeball of whale sharks.

In addition to the whale shark’s entire “teeth apart” teeth, Okinawan researchers have described it as “a strong ability to retract the eyeball into the eyeball”.

When you whale sharks don’t actually have eyelids, both the return strategy and the ‘whole tooth on the eyeball’ make sense. According to the research paper, this adaptation is most unique to whale sharks.

Pretty sure the whale shark has officially become one of the most metal fish in the sea.
