Hippocampus belongs to which group?

Concept

Taxonomic classification places organisms in nested groups according to shared characteristics.

A genus belongs to the broader class and animal group shown by the defining features of its member species.

Application

In this item, Hippocampus refers to the seahorse genus in the family Syngnathidae. Its members are vertebrates with gills, fins, and a bony internal skeleton, placing them among ray-finned fishes.

Contrast

• Mammals have hair and mammary glands; these are not the defining features of Hippocampus.

• Coelenterates, now called cnidarians, are radially symmetrical invertebrates with stinging cells, unlike seahorses.

• Protochordates such as tunicates and lancelets are non-vertebrate chordates, whereas Hippocampus has a vertebral skeleton.

Cross-check

FishBase classifies the genus Hippocampus in the class Teleostei, order Syngnathiformes, and family Syngnathidae, confirming the fish classification.

Therefore, Hippocampus is a fish.
