Endoskeleton
All mammals, birds, reptiles, amphibians, and fish (but not all fish) have internal skeleton.
veterbrate. It has an internal skeleton. Invertebrates have no internal skeleton
Yes, Amphibians are Vertebrates which are animals with backbones.
An amphibian's internal skeleton is important to its survival for a couple reasons. It helps some amphibians escape quickly from danger, and it can help them quickly catch their prey for food.
Arthropods use external skeletons (exoskeletons).
endoskeleton
The internal bony structure is called an "endoskeleton", in contrast to a rigid shell on the outside of the animal, normally made of chitin.Animals that possess these structures are known as vertebrate animals.
verbata
No. Amphibians are not invertebrates. They have an internal skeleton including a backbone which makes them vertebrates.The scientific classification of amphibians is:Kingdom: AnimaliaPhylum: ChordataSubphylum: VertebrataClass: AmphibiaThe largest phylum of invertebrates is Arthropoda, which includes insects.
Insects have an 'exo-skeleton' or outer-skeleton - instead of an internal bone structure.
Internal skeletons in animals are called endoskeletons. These structures provide support, protection, and serve as attachment points for muscles. Endoskeletons are found in various animal groups, including mammals, birds, reptiles, amphibians, and fish.
internal skeleton is meaning that the organism have backbone. So that means that insect is not part of it. Also examples such as jellyfish, squid, octopus, etc. does not fall in internal skeleton group.
