\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Jake, the SeaDog\u00a0<\/em><\/span><\/p>\n Is the barreleye fish\u00a0a newly discovered fish?\u00a0 JD: We have known about this fish for many years.\u00a0 However, most of the specimens were caught in trawls which damaged the specimens.\u00a0 The transparent dome on its head is a recent discovery made possible by using cameras and ROVs to observe the animals alive.<\/p>\n Dr. Drazen, what in the heck is going on with the spookfish\u2019s head?<\/strong><\/p>\n JD: The spookfish has a pair of tubular eyes like binoculars.\u00a0 The eyes are pointed upwards because in its deep-sea home, this is where all the light is coming from.\u00a0 The spookfish looks for shadows of things it could eat made against the very dim light coming from the sun above.\u00a0 Its eyes are very light sensitive but because of the tubes there is a very narrow field of view\u00a0 (What does that mean? Try looking through binoculars or even a pair of cardboard tubes from paper towels. Can you see anything off to the side without moving the binoculars? That’s a “narrow field of view.”)<\/p>\n What puzzled scientists for a long time was that the barreleye has a small mouth and its eyes pointed upward.\u00a0\u00a0 How could it get food into its mouth?\u00a0 Then during a dive with a remotely operated vehicle (ROV) Dr. Bruce Robison observed this fish.\u00a0 At first its eyes were turned upwards as we had always seen them before.\u00a0 Then it did something amazing, its eyes pivoted, turning down so that they looked out in front!\u00a0 The big transparent dome allowed the eyes to move around and see at different angles! (How cool is that?)<\/p>\n Since I can see through\u00a0its head, can I see it thinking?<\/strong><\/p>\n JD: The transparent part is actually over the skull itself so nope you can\u2019t easily see the brain.<\/p>\n Transparent head? Is this the weirdest animal in the sea? Are their other transparent animals?<\/strong><\/p>\n JD: There are lots of transparent animals in the ocean.\u00a0 In the open ocean there are no rocks or seaweed to hide behind so being transparent is a great way to hide from predators.\u00a0 Baby fish, shrimp, and many plankton are transparent.\u00a0 Even some squids and, of course, the spookfish are transparent or have transparent parts of their bodies.<\/p>\n Why should it win the ugly-beauty contest?<\/strong><\/p>\n JD: It may appear ugly but\u00a0its beauty is in how well adapted this animal is to its habitat.<\/p>\n Is this a common deep sea fish? Is it threatened or endangered?<\/strong><\/p>\n JD: \u00a0This is not a very abundant fish but it is commonly found throughout the Pacific, Indian and Atlantic oceans.\u00a0 There are several different species.<\/p>\n What is the most amazing thing about barreleye?\u00a0<\/strong><\/p>\n JD: That it evolved a pair of very sensitive eyes and then overcame the narrow field of view by evolving a transparent dome.\u00a0 It can see and operate in extremely dim light \u2013 equivalent to a dark cloud covered night in the country.<\/p>\n How can I help barrel eyes, hagfish, and other deep-sea animals?\u00a0\u00a0<\/strong><\/p>\n JD: You can help barreleyes and hagfish by reading about the them, watching wildlife shows about the deep-sea (like the Blue Planet series), and telling your friends and family about how interesting these animals are.<\/p>\n To learn more about the Barreleye,<\/p>\n Back to WhaleTimes Hagfish Day!<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" Hagfish Day Star Expert Interview Jeffrey Drazen and the Barreleye Fish (aka spookfish) I shared a few questions with Dr. Jeffrey Drazen, a biologist who studies deep-sea fishes.
