Study Notes
Fish Classification Overview
- Three modern fish groups: Osteichthyes (bony fish), Chondrichthyes (cartilaginous fish), and Agnatha (jawless fish).
- Most fish species in Wisconsin belong to Osteichthyes.
Linnaeus's Classification System
- Classification hierarchy from largest to smallest: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.
- Humans and sharks share the following classification categories: Animalia, Chordate, Vertebrata, Gnathostomata.
Characteristics of Chordates
- Four identifying features of chordates: notochord, dorsal hollow nerve cord, pharyngeal slits, and post-anal tail.
Taxonomy and Naming
- Taxonomy is the scientific classification of living organisms.
- Scientific naming rules entail writing the genus first (capitalized) followed by the species (lowercase), e.g., Zion estano.
Distinctions Among Fish Groups
- Osteichthyes have bony skeletons; Chondrichthyes have cartilaginous skeletons.
- Agnatha represents fish with no jaws and a cartilaginous structure.
Evolution of Early Fish
- Early fish lacked paired fins and jaws.
- Significant evolutionary changes from fish to tetrapod included:
- Flattened head shape.
- Transformation of fins into limbs.
- Relocation of eyes to the top of the head.
- Development of neck bones.
- Formation of vertebrae.
Health Issues Linked to Fish Evolution
- Fish evolution has contributed to certain human ailments, such as choking, hiccups, hernias, and knee problems due to anatomical adaptations.
