What are 2 main types of animals?
The two main types of animals are vertebrates, and invertebrates. This is classified as animals with a back bone (vertebrates), and animals without a back bone (invertebrates).
Why are the fossils of vertebrates similar to the bones of living vertebrates?
Fossils of vertebrates are similar to the bones of living vertebrates because they were once part of living organisms that shared similar anatomical structures and functions. Over time, the bones of vertebrates have undergone evolutionary changes, but many core features have been conserved due to their essential functions. This similarity allows paleontologists to make informed comparisons and infer the evolutionary relationships between ancient and modern vertebrates.
Is a horseshoe crab a vertebrate or invertebrate?
A horseshoe crab is an invertebrate. It lacks a backbone or spine, which are characteristic features of vertebrates.
What is the main function of a notochord?
The main function of a notochord is to provide structural support and flexibility to the body of an organism, particularly during development in vertebrates. It also serves as a basis for the development of the spinal column in vertebrates.
Why is the cephalochordates regarded as closely related to the vertebrates?
Cephalochordates, because of their remarkable morphology, they have proved crucial in understanding the morphology and evolution of chordates in general -- including vertebrates.Cephalochordates have all the typical chordate features. The dorsal nerve cord is supported by a muscularized rod, or notochord. The pharynx is perforated by over 100 pharyngeal slits or "gill slits", which are used to strain food particles out of the water. The musculature of the body is divided up into V-shaped blocks, or myomeres, and there is a post-anal tail. All of these features are shared with vertebrates. On the other hand, cephalochordates lack features found in most or all true vertebrates: the brain is very small and poorly developed, sense organs are also poorly developed, and there are no true vertebrae.
What are the main features of reptiles?
