Prionotus carolinus
Size:
to 16"
Description:
Sea Robins are distinguished by the three free rays of the pectoral fins, with which the fish can actually walk across the bottom. They make frog-like croaking sounds when disturbed. Sea Robins have razor-sharp gill covers and spines, and are best left alone - there's not much meat on them anyway.
Sea Robins are generally found inshore in harbors and inlets, in 30-40 foot depths, but move out to deep waters in winter.
Iron and steel began to replace wood in ship construction in the middle to late 1800s. Timber-poor Europe ( especially England ) led in the development of iron ships, while America, with its vast reserves of lumber, continued to build wooden ships for some time longer. However, as the economical size of ships grew to surpass what could be built of wood, America too began constructing iron ships. For a few years, composite ships were built with iron frames and wooden skins, as seen at right, but difficulties with corrosion between the wood and metal soon led to hulls built completely of metal, both sailing ships and steamers.
