The Comparative Osteology Of The Trunk Skeletons Of Three Species Of Paralichthys, Family Bothidae, From North Carolina, William Marion Hall Jul 1967

The Comparative Osteology Of The Trunk Skeletons Of Three Species Of Paralichthys, Family Bothidae, From North Carolina, William Marion Hall

Master's Theses

Paralichthys albigutta Jordan and Gilbert, the gulf flounder, which occurs over sand bottoms, and Paralichthys let:nostigma Jordan and Gilbert, the southern flounder,which occurs over mud bottoms , are southern species with ranges extending into the Gulf of Mexico.Paralichthys dentatus, the summer flounder, is tho northern species and is tolerant of several types of bottoms but is most frequently found over sand or hard bottoms. The ranges of the three species overlap in an area along the eastern coast of the United States from central North Carolina to near Jacksonville, Florida. The flounders are closely related and unless the pig­ment pattern …


The Comparative Osteology Of The Skulls Of Three Species Of Paralichthys, Family Bothidae, Anne Caperton Beirne Jan 1966

The Comparative Osteology Of The Skulls Of Three Species Of Paralichthys, Family Bothidae, Anne Caperton Beirne

Master's Theses

This study was undertaken to determine if there were osteological variations in the skulls of young summer flounders, Paralichthys dentatus (Linaeus), southern flounders, Paralichthys lethostigma Jordan and Gilbert and - gulf flounders, Paralichthys albigutta Jordan and Gilbert that could be used as bases of species separation. As two of the species (dentatus and lethostigma) are of considerable economic importance, it would be of substantial value to establish skeletal characters that would help identify the young and. subsequently aid in determining their particular habitats where they occur in the same area.The three are closely related and difficult to recognize unless the …
