Round-spotted transparent lionfish
A biologist recently led a team to discover a transparent fish while exploring the waters of Alaska . This is a rare round-spotted transparent lionfish, also known as crystal fish. Its scientific name is Crystallichthys cyclospilus. It is a deep sea-dwelling fish and is carnivorous.
Sarah Friedman, a fish biologist with the National Oceanic and Atmospheric Administration (NOAA), wrote on Twitter: "I've wanted to see this crystal fish in person for a long time.
Sarah told the American Internet news blog Mashable: "We have found four or five within a few weeks of traveling," and her team encountered them during a routine annual survey of the Aleutian Islands near Alaska (Alaskan). Here comes the fish.
But that doesn't mean they are common. "Crystal fish are found from depths of 100 to 200 meters. So I would say the average person would never come across these fish," she explained.
Crystal fish is transparent, light red, and very beautiful. The reason why it looks like this is not unreasonable. This is the result of adapting to the deep sea environment. Red light has the shortest wavelength, so it cannot reach the deeper parts of the ocean. The light red body is not easily visible to predators due to the lack of red light scattering.
Sarah said that another cool feature of the crystal fish is that it has suction cups on the bottom of its body. It can be firmly attached to rocks and will not be washed away by rapids. Several other fish species also have this function, such as squid.
Sarah also tweeted about some other interesting species seen during the expedition, including the deep-sea anglerfish, also known as lanternfish or monkfish , which lives at a depth of at least 2,000 meters in the complete absence of light. Living everywhere, there is a rod on its forehead, which contains millions of luminous bacteria , which will sparkle. This is to lure prey out of the dark depths of the ocean.
