Northern Sea Robin

Northern Sea Robin

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.

The Sea Robin uses its "legs" to walk across the bottom and even turn over small stones.

Divers can appreciate these extraordinary creatures, although fishermen revile them.

Specific gravity is the ratio of the density of a material to the density of water. Materials with a specific gravity greater than 1.000 ( 1.035 in the ocean ) sink; materials with a specific gravity less than 1.000 ( 1.035 in the ocean ) float. Lead has the highest specific gravity - 11.35, except for gold. Gases like air also have weight, density, and specific gravity.

These figures are approximate and should be used only as general indicators.
