The phylogenetic classification of marine life organizes organisms based on their evolutionary relationships, showing which groups share a common ancestor. Rather than relying solely on appearance, this approach uses genetics and evolution to group living beings into clades, or branches of the tree of life. This helps to better understand how marine biodiversity has developed and how different ocean animals and plants are connected through evolution.

Among marine organisms are seaweeds and marine plants, invertebrates such as sponges, corals, mollusks, and crustaceans, and marine vertebrates like fish, dolphins, seabirds and marine reptiles. This classification provides insight into the diversity of species and the specific adaptations they have developed to survive in the ocean, whether for swimming, feeding or breathing.

Find all data related to our sea plants as well as our sea animals listed according to the phylogenetic tree, with the name of the phylum to which they belong, the class, the order, the family, the common name and to finish the scientific name itself made by the genus name followed by the specie name !

In opposite to common names, the scientific name is unique and same whatever the language. Thus it provides a unique name to make sure people are referring to the same marine specie. This is not the case with common names.
