Learn With Cool Ichthyology Terms Flashcards

Ichthyology Terms flashcards are a set of study tools designed to help students learn key vocabulary related to the study of fish. These flashcards typically include terms like gills, scales, dorsal fin, and more.

The subject of Ichthyology is the branch of zoology focused on the study of fish. It involves understanding the anatomy, physiology, behavior, and classification of fish species. Ichthyologists often conduct research to learn more about fish habitats and populations.

quick facts

Ichthyology is the scientific study of fish, including their classification, anatomy, physiology, behavior, and distribution.
Oviparous is a term used to describe fish that lay eggs which hatch outside of the mother’s body.
Viviparous refers to fish that give birth to live young, rather than laying eggs.
Lateral line is a sensory organ found in most fish that allows them to detect changes in water pressure and vibrations in the surrounding environment.
Gill slits are openings on the side of a fish’s head that allow water to pass over the gills, where oxygen is extracted and carbon dioxide is released.
