The freshwater drum is also called Russell fish, shepherd's pie, gray bass, [7] Gasper goo, Gaspergou, [8] gou, [8] grunt, grunter, [7] grinder, gooble gobble, and croaker. It is commonly known as sheephead and sunfish in parts of Canada, [ 9 ] and the United States.
The drum were caught using shrimp for bait on 80 lb braided line and steel leaders. Black drum caught in Lake Pontchartrain. Black drum are bottom feeders, so they are most commonly caught with bait either on the bottom or suspended within a couple feet of the bottom. Bottom fishing methods are used both in surf fishing and inshore fishing. [14]
Cartilaginous fish, such as sharks, do not have any of the bones found in the lower jaw of other vertebrates. Instead, their lower jaw is composed of a cartilaginous structure homologous with the Meckel's cartilage of other groups. This also remains a significant element of the jaw in some primitive bony fish, such as sturgeons. [11]
Magnified view of freshwater drum otolith showing growth bands. University of Minnesota Biologist George R. Spangler gives a technical explanation of the "letters" which appear on the lucky stone. "The 'L-shaped groove' is technically known as a 'sulcus'. In the living fish, the sulcus is adjacent to a series of neuromast cells in the inner ear.
The hyomandibula, commonly referred to as hyomandibular [bone] (Latin: os hyomandibulare, from Greek: hyoeides, "upsilon-shaped" (υ), and Latin: mandibula, "jawbone"), is a set of bones that is found in the hyoid region in most fishes. It usually plays a role in suspending the jaws and/or operculum (teleostomi only).
The blackbar drum has a deep, rhomboid body with an arched dorsal profile. The head is low, with a moderately large eye and a snout protruding beyond the mouth, with a notched upper jaw which encloses the lower jaw. The villiform teeth are arranged in bands with those in the outer row of the lower jaw being enlarged and resembling canine teeth.
Forensic genealogists solve a 21-year-old case, linking a jawbone to a U.S. Marine captain who died more than 70 years ago in Orange County.
Osteichthyes (bone-fish) or bony fishes are a taxonomic group of fish that have bone, as opposed to cartilaginous skeletons. The vast majority of fish are osteichthyans, which is an extremely diverse and abundant group consisting of 45 orders, with over 435 families and 28,000 species. [21] It is the largest class of vertebrates in existence today.
