Feeding Strategies And Functional Morphology Of Demersal Deep-Sea Ophidiid Fishes, H. Jacque. Carter
Feeding Strategies And Functional Morphology Of Demersal Deep-Sea Ophidiid Fishes, H. Jacque. Carter
Dissertations, Theses, and Masters Projects
The hypothesis is advanced that ophidiid fishes prevalent beneath oligotrophic tropical seas have evolved trophic specializations appropriate for existence in regions of low primary productivity where ultimate energy available for food production in benthic communities is low. The feeding strategies of these tropical dwelling deep-sea fishes are discussed within the context of this hypothesis. The feeding strategies of tropical dwelling deep-sea ophidiid fishes are examined through an analysis of food habits and examination of morphological features related to feeding. Three main modes of feeding are evident among these fishes: (1) predation upon small benthopelagic or planktonic organisms by small-bodied species …
On The Anatomy And Phylogeny Of The Zoarcidae (Teleostei: Perciformes), M. Eric. Anderson
On The Anatomy And Phylogeny Of The Zoarcidae (Teleostei: Perciformes), M. Eric. Anderson
Dissertations, Theses, and Masters Projects
The eelpouts, Zoarcidae, are a group of bony fishes, most species of which inhabit continental shelves and slopes of boreal seas. There are about 200 species of eelpouts, most of which are rare in collections, thus they have been only cursorially studied by most workers. as a result, the systematics of the family is in a poor state. This work is a contribution to the improvement of that state. The anatomy of all nominal genera of Zoarcidae was studied in an attempt to reconstruct phylogeny and establish the limits of genera. From analysis of a matrix of 63 characters, the …
Anatomical Observations On The Ampullae Of Lorenzini From Selected Skates And Galeoid Sharks Of The Western North, William Raschi
Anatomical Observations On The Ampullae Of Lorenzini From Selected Skates And Galeoid Sharks Of The Western North, William Raschi
Dissertations, Theses, and Masters Projects
The gross structure of the ampullae of Lorenzini and its distribution on the body of 40 species of skates (Rajoidei) and 5 species of sharks (Galeomorphii) were compared in an attempt to investigate correlations within this system to feeding mechanisms. Three general lines of morphological change are observed. A larger proportion of the ampullary pores are associated with the ventral surface of the dorsoventrally flattened skates than the more conically shaped sharks. The relative proportion of ventral pores is significantly reduced on those species inhabiting aphotic waters. Secondly, the more piscivorous rajoids possess an array of ventral pores which covers …
