Reptiles are considered true land vertebrates because they possess adaptations that enable them to thrive in terrestrial environments. Their waterproof skin, made of scales, reduces water loss, allowing them to live in dry habitats. Additionally, reptiles have evolved amniotic eggs, which provide a protective environment for embryonic development without the need for water. These features distinguish them from amphibians, which typically require moist environments for reproduction and survival.
Reptiles were the first true land vertebrates because they were able to successfully adapt to terrestrial environments with features such as scales to prevent water loss, amniotic eggs for reproduction on land, and efficient respiratory systems for breathing air. These adaptations allowed reptiles to thrive on land, marking a significant evolutionary shift from their amphibian ancestors.
One is that the first reptiles (not dinosaurs!) appeared. The land during this peiod was swamp-forests.
Yes, an emu is a vertebrate as are all other birds. They have an internal skeleton and a backbone which makes them vertebrates. All mammals, reptiles, amphibians and fish (true fish) are also vertebrates.
That is actually not true. The vast majority of animals, including vertebrates and invertebrates, are insects. All insects live on land. As for vertebrates, three of the seven classes are types of fish, and fish species equal the number of terrestrial vertebrate species, at approximately 32,000 types of fish compared with 10,000 reptiles, 10,000 birds, 5,000 mammals, and 7,000 amphibians.
Yes. A good rule of thumb is that only true fish (which includes sharks), birds, mammals, reptiles and amphibians are vertebrates usually. I DONT CARE -__-
No, but it is a vertebrate. ;]A vertebrate is any animal with a spine, - that is, a set of vertebrae - including all fish, birds, reptiles, and mammals.
All land vertebrates (including humans) can trace their origins back to the first fish that began crawling on the land using their strong, jointed fins. Eventually, the fish became more adapted to dry land and became amphibians. However, these amphibians still laid their eggs in water, and their young were tadpoles that spent all their time in water. The first true land vertebrates were reptiles, who were born on land and spent almost all their time on land. A small group of these reptiles became warmblooded and started growing hair, so they became the first mammals. Mammals remained small until the extinction of the dinosaurs, when they were given more room to grow, diversify, and give rise to humans.
true
Birds are more closely related to reptiles than they are to mammals. Birds, reptiles, and mammals all belong to a group of vertebrates called amniotes, which split off from amphibians. Amniotes split into two groups soon after they evolved: true reptiles and synapsids. Mammals are the only living synapsids today. Dinosaurs branched off from the reptiles and birds then evolved from the dinosaurs.
Fish are classified as vertebrates because they have an internal skeleton.
True. All reptiles are cold blooded
All vertebrates belong to the taxonomic domain of Eukarya, members of which are characterised by having cells with nuclei. Vertebrates include birds, mammals, fish, reptiles and amphibians. Eukarya covers all organisms in the Kingdom Animalia, as well as the Kingdoms Plantae, Fungi and Protista.
