Study Notes
Ichthyology, Fish Species Classification, and Fish Anatomy
Ichthyology
Ichthyology is the branch of zoology concerned with the study of fish. While it is not a separate field, it is a specialized area of study within zoology that focuses on the biology, behavior, and ecology of fish. Ichthyology involves the classification, evolution, and anatomy of fish. Scientists who specialize in ichthyology are called ichthyologists.
Fish Species Classification
Fish species are classified using a hierarchical system called taxonomic classification. This system is organized from the largest and most general to the smallest and most specific: kingdom, phylum, class, order, family, genus, and species. Fish belong to the kingdom Animalia, the phylum Chordata, and from there are grouped more specifically into several classes, orders, families, and thousands of genus and species. For example, the largemouth bass, Micropterus salmoides, is classified as follows:
Taxon Latin Name
--------------------------------------------------------
Kingdom Animalia
Phylum Chordata
Class Osteichthyes
Order Perciformes
Family Centrarchidae
Genus Micropterus
Species Salmoides
Fish Anatomy
The anatomy of fish is diverse and adaptive, allowing them to inhabit a wide range of aquatic environments. Some common external anatomy features of fish include:
- Dorsal fin
- Anal fin
- Caudal fin
- Pectoral fins
- Ventral fins
- Gills
- Lateral line
- Nares
- Mouth
- Scales
- Teeth (in some species)
Fish species also exhibit variation in their anatomy based on their ecological adaptations. For example, a fish with a superior mouth (i.e., a mouth located at the top of the body) may indicate that the fish feeds near the surface, while a fish with a protractile mouth may suggest it feeds on the bottom. Similarly, a fish with a sharp, forked tail like that of a tuna implies a fast swimmer, whereas a rounded tail like that of a blackfish indicates the fish is good at turning.
