In this article I will answer if Lizards have bones, if they are vertebrates or not and reveal other interesting related biological facts. I was tempted to research this article after seeing some confusion and interest into lizards bone structure and to clarify even if they had bones.<\/p>\n
Do lizards have bones? Yes, they have bones. They are vertebrates and have a backbone along with a collection of other bones. They also have Kinetic skulls that have moving parts. The exact bone structure varies from specie to specie.<\/strong><\/p>\n Now that you understand that lizards have bones lets delve a bit deeper and understand a bit more detail about these lizards, in particular their bones and general anatomy.<\/p>\n As briefly discussed earlier. Lizards do have a backbone. This is the same as humans and they are commonly referred to as vertebrates.<\/p>\n A vertebrate is basically any animal that has a backbone. This includes us humans, reptiles, etc. The opposite of this is invertebrates, who do not have a back bone. Invertebrates have soft bodies without a backbone. An example of this would be jellyfish or a the common garden worm.<\/p>\n Lizards typically have a Kinetic skull meaning that it has moveable joints. The term for this movement is typically referred to as\u00a0Cranial kinesis<\/a>.<\/p>\n It basically means that apart from the normal upper and low jaw movement there is movement in other skull bones. Humans do not have such skull movement, and are commonly referred to as having akinetic skulls, the opposite to kinetic.<\/p>\n Yes, lizards do shed their skin. It is a natural part of being a lizard in fact. For example Iguanas are known to shed their skin every 4-6 weeks. Younger lizards are even known to shed their skin even more frequent.<\/p>\n You usually get some clear signs when your lizard is about to or just starting to shed its skin. Such as the following:<\/p>\n The shedding can take up to three weeks to complete. However this varies quite a bit. For example an Alligator lizard can literally shed its entire skin in hours. This is mainly due to the fact that it does this in one go and sheds its whole skin in one session.<\/p>\n There are problems that can occur during this process. If the shed does not occur correctly this is called\u00a0dysecdysis<\/em>. This can be caused by a poor diet, but in other cases thier could be other reasons that could make this happen.<\/p>\n Don’t be surprised if find your lizard eating its own skin after its shedded. I know, this may sound unpleasant, but this is actually a healthy and natural thing for lizards.<\/p>\n They benefit from the minerals in the skin and eating the skin helps them re-generate a new skin faster.<\/p>\n The parietal eye is commonly referred to as the the “third eye”. It is also sometimes called the Pineal eye. Lizards have this Parietal eye. It is particular useful to them to detect and decipher light levels.<\/p>\n When I say light levels, I mean working out when it is light and day. The eye will detect changes in the time of day based on colour changes of daylight.<\/p>\n Do Lizards Have Red Blood?<\/strong> Before we answer this question, first let’s understand what actually makes blood red. The hemoglobin in . the oxygen is what gives blood the red colour. Which is present in human blood. This is the same for lizards, but not for all species.<\/p>\n Some species, in particular in New Guinea, there is a type of Skink Lizard that has green blood. Not just blood is green, also the muscles, bones and organs have this green colouration.<\/p>\n But why is its blood green? The reason is this lizard does not have the hemoglobin that we talked about earlier, meaning they do not have the same red colour we have.<\/p>\n Do lizards have teeth?<\/strong> Yes, lizard do have teeth, but they are different to our teeth. Depending on which specie of lizard you look at some have teeth that look more like little pegs.<\/p>\n However, a Komodo Dragon for example, has sharp serrated teeth that can injure animals that they wish to eat. Then on the other end of the scale you have the Mollusk that has blunt teeth.<\/p>\n Do Geckos have bones?<\/strong> Yes, they do have bones and what has been discussed earlier actually address this. All lizards have bones and are vertebrates.<\/p>\n What is Bipedal running and which Lizards can do this?<\/strong>\u00a0This is basically running on two legs. Essentially this is what we do as humans. Obviously Lizards have four legs, so this is more of an interesting thing to see for them.<\/p>\n The Basilisk lizard can do this. It uses its two legs and uses its tail as a balance for their weight. AN interesting fact about these Basilisk lizards<\/a> is they can actually run across water for short distances.<\/p>\nDoes a lizard have a backbone?<\/h2>\n
