Description: Southeast Florida witnesses an enormous seasonal influx of upper trophic level marine
predators each year as massive aggregations of migrating blacktip sharks (Carcharhinus
limbatus) overwinter in nearshore waters. The narrow shelf and close proximity of the Gulf
Stream current to the Palm Beach County shoreline drive tens of thousands of sharks to the
shallow, coastal environment. This… more

Description: The cartilaginous and non-neopterygian bony fishes have an electric sense typically comprised of hundreds
or thousands of sensory canals distributed in broad clusters over the head. This morphology facilitates
neural encoding of local electric field intensity, orientation, and polarity, used for determining the position
of nearby prey. The coelacanth rostral organ electric sense, however, is… more

Description: In the aquatic environment, living organisms emit weak dipole electric fields, which spread in the surrounding water.
Elasmobranchs detect these dipole electric fields with their highly sensitive electroreceptors, the ampullae of Lorenzini.
Freshwater sawfish, Pristis microdon, and two species of shovelnose rays, Glaucostegus typus and Aptychotrema rostrata were
tested for their reactions… more
