Species Composition And Reproductive Strategies Of Commensal Synalpheus Shrimp (Decapoda:Alpheidae) Occupying The Sponges Spheciospongia Vesparium And Spongia Sp. Of The Florida Reef Tract, Brittnee Nicole Barris

HCNSO Student Theses and Dissertations

Synalpheus shrimp species of the gambarelloides group are the only marine organisms displaying the highest level of social functioning, eusociality. Their social hierarchies are equally complex compared to the reproductive abnormalities that have been recently discovered. For instance, snapping shrimp of the genus Synalpheus were thought to be gonochoric, i.e. developing as independent sexes, until scanning electron microscopy studies revealed intersexed gonopores in several species. This project analyzed both the species composition, and accompanying reproductive structures, of Synalpheus spp. (Caridea: Alpheidae) comprised of densely aggregating communal and pair-living colonies in the Florida Keys, Florida.

Colonies of pair-living and communal Synalpheus …

The Yellow Stingray, Urobatis Jamaicensis (Chondrichthyes Urotrygonidae): A Synoptic Review, Richard E. Spieler, Daniel P. Fahy, Robin L. Sherman, James Sulikowski, T. Patrick Quinn

Marine & Environmental Sciences Faculty Articles

The yellow stingray, Urobatis jamaicensis (Cuvier) has been the subject of a multitude of diverse studies on its natural history, morphology, and physiology. We have attempted here to briefly review all the studies on U. jamaicensis both published and unpublished with the goal of providing comparative information for researchers working on related species as well as to highlight areas of research requiring further investigation in this one.

Notes On The Biology Of Invasive Lionfish (Pterois Sp.) From The Northcentral Gulf Of Mexico, Nancy J. Brown-Peterson, J. Read Hendon

Gulf and Caribbean Research

The first confirmed sightings of lionfish in the Gulf of Mexico occurred in 2010 (Schofield 2010), where they were reported in the southern GOM off the Yucatan Peninsula, Mexico (Aguilar-Perera and Tuz-Sulub 2010); in 2012 more than 1,500 lionfish were collected from northern GOM locations ranging from Florida to Texas (Fogg et al. 2013). However, other than visual observations (mostly from recreational divers), there is relatively little information on the biology and ecology of lionfish in the northern GOM. The life history of invasive species can vary as they colonize new habitats and areas (Bøhn et al. 2004); thus, biological …
