Highly cephalized well developed sense organs and brain endoskeleton an animal with back bone... birds, squirrel, dogs, cats, etc.
Sexual reproduction is the primary characteristic used to classify the types of animal-like protists. However, determining if the protist is multi-cellular is also another primary characteristic.?æ
You can classify different species of animals based on their common characteristics, such as physical features or behaviors.
Scientists use common features such as body structure, genetic makeup, reproductive methods, and behavioral patterns to classify organisms into different groups or taxa. These features help to understand the relationships among different species and their evolutionary history.
Homologous structures are features that originated in a shared ancestor, such as the bones in the limbs of vertebrates. These features may have different functions in modern organisms but have similar underlying structures due to their common ancestry.
Scientists now use DNA to classify organisms because it provides more accurate and reliable information about the evolutionary relationships between different species. DNA analysis allows for a more precise classification based on genetic similarities, which can be more informative than physical characteristics. Additionally, DNA analysis is less subjective compared to evaluating external features, making it a more standardized approach to classification.
scientists classify organisms into groups based on internal and external features.
A horseshoe crab is an invertebrate. It lacks a backbone or spine, which are characteristic features of vertebrates.
Because some animals have features of different groups of vertebrate. For example the duck built platypus is classified as a mammal but has some bird (a beak) and it lays eggs which a mammal doesn't do.

They have a spine.

Reptiles classify as animals because they meet key characteristics of the animal kingdom. They are multicellular, eukaryotic organisms that consume organic material for energy. Reptiles are vertebrates, breathe oxygen, and reproduce sexually or asexually. Unique to reptiles, they have scales, lay amniotic eggs, and are ectothermic (cold-blooded) creatures. visit our website: www. ieqsgroup .com/services-eddy-current-testing/
A characteristic typically shared by all organisms in a group is known as a synapomorphy, which is a derived trait that reflects a common ancestry. These homologous structures can include specific anatomical features, genetic sequences, or developmental patterns that have evolved over time. For example, the presence of vertebrae in all vertebrates is a synapomorphic trait that unites this diverse group of animals. Such shared characteristics help scientists classify and understand evolutionary relationships among different organisms.
Black widows external features are, they are black with a red hour glass on its back.

First, our spines make us vertebrates. Giving live birth, and female milk glands are two features that make us mammals.
