Somebody slap a lawsuit on the dentist who fitted this fish with the freakishly human tooth… What’s that you just say? Evolution did this. By pure choice? What was it considering!
The sheepshead fish, aka the lovechild of Billy Bass and my granny’s dentures, is a scaly, sparkly swimmer that may be discovered within the shallow waters of the western Atlantic, from Nova Scotia to Brazil. It’s a euryhaline species, which suggests it will probably tolerate a variety of salinity.
Whereas the fish normally lives in coastal waters and estuaries, they generally head to freshwater to search out heat in winter. In days passed by, the fish could possibly be noticed in Brooklyn’s Sheepshead Bay, which was named after it, however then the Bay turned polluted and the fish disappeared.
Nobody is aware of precisely why it’s known as the ‘sheepshead’ fish, when its tooth are clearly the principle occasion, however some say that its blunt snout and nearly horizontal mouth are certainly sheep-like. Its gray and black stripes do, nevertheless, lend themselves to its different moniker of the convict fish. Put one in jail subsequent to a prisoner in a striped uniform and it shouldn’t appear to be a fish out of water.
Freshly hatched sheepshead fish are tiny and toothless. They dine on smooth meals, resembling marine worms and plant matter. Their tooth begin to come via as they method 5cm (2in) in size, and from then on, the fish begin to deal with extra strong, shelled prey, resembling barnacles, clams, crabs and oysters.
Grownup sheepshead fish, which develop as much as 75cm (30in) lengthy, have three rows of tooth of their higher jaw, and two rows lining their backside jaw. These embody chisel-shaped incisor-like tooth on the entrance, and flatter molars and rounded grinders in the direction of the again. All of which are coated in a tough, enamel-like substance, laid on prime of a calcified dentin inside.
This seemingly motley assortment of gnashers, which isn’t so totally different to our personal, is an adaptation to the fish’s omnivorous weight-reduction plan. Evolution has chosen for this association as a result of it allows the fish to chew, crush and grind, and exploit a wealthy number of meals sources. The sheepshead fish is understood to eat greater than 100 totally different species. That is a part of the rationale why it has been so profitable.
One more reason is that it has comparatively little meat on its physique and sharp dorsal spines, which make it troublesome to fillet. Though the meat is good, with a flaky, tender texture, business fisheries have traditionally focussed on different, extra economically viable species, such because the pink drum. This might change, nevertheless. Though the sheepshead fish is comparatively plentiful now, as shares of pink drum and different native fish decline, there are considerations that the toothy icon could possibly be subsequent.
Within the meantime, don’t fear should you encounter one. Sheepshead fish don’t chew (except you’re a clam or an oyster), however they do have a smile that might soften the guts of even essentially the most detached orthodontist.
