Long Island Sound - West Chart

Long Island Sound - East Chart

Long Island Sound averages 60 ft in depth, with the greatest depth of over 300 ft at the eastern end. Tidal effects are strongest at the narrow western end, where all the inrushing water flow piles up and makes tidal variations of up to 7 ft. Strong tidal currents are also prevalent, and visibility tends to be poorer than the open ocean, especially at depth.

These fish are Wrasses, northern representatives of a widespread tropical family that includes Parrotfishes. Wrasses propel themselves slowly and precisely with their pectoral fins, using the tail only in emergencies. Tropical Wrasses feed on coral. Lacking this, their northern cousins feed primarily on mussels and other shellfish.
