Magical invisible animal

  We all know that squid and octopus can use pigment cells to integrate themselves into the surrounding environment, but what if they become completely invisible? Transparency is a very cunning skill, and some animals do this.
  Animals living close to the sea will use the bioluminescence effect to display dazzling color effects when hiding, making predators lying below mistakenly believe it is the ripples produced when the sun shines on the water surface. Animals living in the middle layer of the pelagic zone do not have these two options, and there is also the place where the most invisible animals live.
  Perhaps the easiest way to become invisible is to become transparent so that light can pass through the body completely.
  Glass octopus
  glass octopus named because their body is almost completely transparent. This gelatinous octopus can grow up to 45 cm long-if you count the tentacles. They are distributed in tropical and subtropical waters and move at depths between 300 meters and 1,000 meters. With the exception of the digestive system, optic nerve and eyes visible, the glass octopus is almost completely invisible to predators.
  Salps
  Salps is almost completely transparent, barrel-shaped creatures, its gelatinous body, they can while swimming and feeding by suction and discharge waters. Salps rely on the plankton in the seawater to be filtered for their livelihoods. Although they look a bit like jellyfish, they are actually more complex and more closely related to fish and vertebrates. They also have a heart and gills and can reproduce sexually.
  Glass squid
  squid also has a lot of transparent members, mainly belonging to the head squid families, with about 60 species, almost all can see through. These squids live in various open ocean regions of the world, with a depth of 200 meters to 1,000 meters. Although the body is completely transparent, their large eyes are not transparent, and predators swimming below can easily spot the shadows cast by their eyes. However, the glass squid has a clever way of disguising. They can use the luminous body under the eyes to create the effect of “luminescence and shadow elimination”. This is a bit like the situation where the sun shines through a filter, so that the squid can hide in the background and not be spotted by predators below.
   Researchers from the University of Pennsylvania found that the luminous bodies of these squids can adjust the light emitted to offset the light in other directions, thereby forming a certain all-round invisible effect.

  When it was cold, the ants retracted into the ant nest, and the small groups of worker ants on the side of the road disappeared. But this can’t affect the ants. They still search the ground or tree trunks every day. When they find that the ant nest sticks out an incredible pink tongue, it sweeps away the ants in the nest.
  An ant bounces and walks on the ground. People who are not familiar with birds may think of it as a “larger” sparrow-the feathers are dark brown, the back of the occiput has black diamond-shaped patches, and the abdomen is covered with horizontal spots and mottled. Messy, the body color pattern is just like a section of old tree bark, not much bigger than a sparrow. But ants and sparrows are biologically separated by tens of thousands of miles. They are a kind of woodpecker, although they do not pecker at all.
  Ants have sharp claws, sharp beaks, and extra-long tongues that circle the skull. They also build nests in tree holes, but when climbing on a tree trunk, they never hit the tree trunk. They just clasp the bark with their claws and head down. , Closed his eyes, standing like a small withered branch. The invisibility techniques are so superb that it is difficult for people to find them.
  This kind of bird is lonely, and its individual combat effectiveness is very weak. When confronted with threats, the stealth camouflage has no effect. They take out another camouflage-quickly twisting their necks 180 degrees, imitating snakes, twisting their bodies, and even spit out Long tongue, pretending to be a snake with super attack power, to scare off threats. Therefore, ants are often called crooked-necked birds and snake-necked birds in folk.
  Most of the time, the ants simply stand still and pretend to be dead as soon as they close their eyes, trying to hide their whereabouts as much as possible.
