Caption: Bonnethead sharks
are the first known shark species to get nutrients from eating plants.
The other fishes that we tested are senorita wrasses (Oxyjulis californica), bonnethead sharks
(Sphyrna tiburo), mummichogs, or killifish (Fundulus heteroclitus), and pinfish (Lagodon rhomboides).

An energy equivalence of 13.6 J/mg [O.sub.2] was used to convert the [VO.sub.2] consumed into energy (Schindler et al., 2002), and a [Q.sub.10] value for the bonnethead shark
(Sphyrna tiburo) of 2.3 (Carlson and Parsons, 1999) was used to adjust the final metabolic rate to 18.8[degrees]C (the preferred temperature of shortfin makos in the northwest Atlantic; Stillwell and Kohler, 1982).
The fish turned out to be a spunky bonnethead shark
, but the long fight had Boyd pirouetting around the deck and whooping more excitedly than a Miami Dolphins fan.
Cortes and Parsons (1996) compared the demography of two Floridian populations of the bonnethead shark
(Sphyrna tiburo), which included several life history measures in the life table analyses, but the small spatial resolution was inadequate to indicate large-scale spatial life history correlations within this species.
Expect to catch trout, ladyfish, Spanish mackerel, small jacks for sure, and you might see a cobia, bonnethead shark
, or a pompano.

Drifting the flats with a shrimp/rattling float rig is just about guaranteed to produce at least a few trout, and don't be surprised if a pompano, a bonnethead shark
or a cobia slurps your shrimp.
