Difference between Catfish and Clade

Catfish vs. Clade

Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. In biological phylogenetics, a clade, also known as a monophyletic group or natural group, is a grouping of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree.

Basal (phylogenetics)

In phylogenetics, basal is the direction of the base (or root) of a rooted phylogenetic tree or cladogram.

Cladistics

Cladistics is an approach to biological classification in which organisms are categorized in groups ("clades") based on hypotheses of most recent common ancestry.

Extinction

Extinction is the termination of a taxon by the death of its last member.

Lineage (evolution)

An evolutionary lineage is a temporal series of populations, organisms, cells, or genes connected by a continuous line of descent from ancestor to descendant.

Monophyly

In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of taxa which meets these criteria.

Morphology (biology)

Morphology in biology is the study of the form and structure of organisms and their specific structural features.

Neontology

Neontology is a part of biology that, in contrast to paleontology, deals with living (or, more generally, recent) organisms.

Sister group

In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree.

Taxonomy (biology)

In biology, taxonomy is the scientific study of naming, defining (circumscribing) and classifying groups of biological organisms based on shared characteristics.

Vertebrate

Vertebrates are deuterostomal animals with bony or cartilaginous axial endoskeleton — known as the vertebral column, spine or backbone — around and along the spinal cord, including all fish, amphibians, reptiles, birds and mammals.
