All right folks, I have an exciting line up of Wild Facts for you this week. Each day this week will be a fact about bizarre and interesting animals on this planet.\u00a0 You may have heard of some of these animals but they are not common.\u00a0 So make sure you check out Wild Facts each day this week to get the scoop on some very unusual animals.<\/p>\n

I wanted to start the week off strong so I am going to give you the down low on an animal that has a transparent head.\u00a0 I told you this was going to be an unusual week! The barreleye fish is a deep sea fish that is usually under 20 cm long (although some species can be larger).\u00a0 They live in the deep ocean depths where the sunlight can’t reach.\u00a0 This type of environment often causes some unique adaptations.<\/p>\n

Obviously, a transparent head can be deemed as an unique adaptation.\u00a0 So what is the purpose of having a transparent head?\u00a0 Come on, it is awesome, isn’t that enough for you?? Well, I failed to mention another interesting adaptation that the barreleye fish has and as the name suggests it has to do with their eyes.\u00a0 You see, the barreleye fish has tubular eyes that protrude from their skull but are enclosed in their transparent dome.\u00a0 These type of eyes are very good at collecting any little bit of light that may be finding its way to the deep ocean depths.\u00a0 The eyes of the barreleye fish generally look up so they are able to detect slight movements in their prey directly above them. For awhile, scientists believed that the eyes could only look up but recent studies have indicated that the barreleye fish is able to direct their unique eyes forward to see what they are eating. These astonishing adaptations just go to show how incredible evolution can be and that there are no limits to an animals survival in this harsh world.<\/p>\n

Make sure you check out the video post below to see more on the barreleye fish.<\/p>\n

Before you go to the video, I want you to look at the picture above again.\u00a0 Notice the large green things in the head.\u00a0 Well that is the barrelfish eyes (acutally, it is their lens but for our purposes it is the same).\u00a0 The typcial eyes on the front of the face are actually the nostrils of the barreleye fish.\u00a0 Pretty cool, eh?<\/p>\n
