The word "acanthopterygii" is a mouthful to spell and pronounce! It refers to a group of fish that have spiny fins. The word is spelled with the prefix "acantho," which comes from Greek meaning "thorn" or "spine," and "pterygii," which means "fins." The IPA phonetic transcription for "acanthopterygii" is /əˌkænθoʊˌptɛrəˈdʒiː/ or "uh-KAN-thoh-PUH-tuh-ruh-jee."

Acanthopterygii refers to a diverse and large group of fish species belonging to the class Actinopterygii, which includes most of the bony fishes. This taxonomic group is characterized by the presence of spiny rays, known as "spines," on their dorsal and anal fins. The name "acanthopterygii" is derived from the Greek words "akantha" meaning "spine" and "pteryx" meaning "fin," reflecting this distinctive feature.
The Acanthopterygii group encompasses a wide range of fish families, such as the Percidae (perches), Serranidae (groupers), Centrarchidae (sunfishes), and Pomacentridae (damselfishes). They are predominantly marine but can also be found in freshwater environments. These species vary greatly in size, shape, and behavior, showcasing a remarkable diversity within the group.
Members of Acanthopterygii are known for their ability to rapidly change direction while swimming, thanks to their highly maneuverable and flexible spiny fins. These spines can be locked into an extended position for defense or kept folded into a groove to minimize drag during fast swimming.
The Acanthopterygii group plays a vital role in various ecosystems, serving as both predators and prey. They exhibit a wide array of feeding strategies, including herbivory, omnivory, and piscivory, contributing to the ecological balance within their habitats. Their economic importance cannot be undermined either, as certain members are extensively fished for both subsistence and commercial purposes.
