Buzzards Bay and adjacent waters are an area strongly affected by the Gulf Stream, which tends to push water toward Rhode Island, creating longshore currents that terminate exactly there. A map will illustrate the reasons for this phenomenon. The Stream almost collides with Conn. and R.I., and currents it creates run north along the coast until they are absorbed into Buzzards Bay. The result is that Buzzards Bay, which is really the inside of the Cape Cod curve, and the islands of Martha's Vinyard and Nantucket receive numerous Gulf stream strays, even into the winter. There is a program on Cape Cod that devotes itself to checking the beaches in late September into October every morning to rescue stranded sea turtles, mostly Ridleys, which wash up in large numbers onto Cape beaches, shocked by the suddenly cold water. These turtles have ridden the stream, as do many, many tropicals and semi-tropical fishes. The only Caribbean Blue Tang I have ever seen north of the Carolinas was in a jetty on Marthas Vinyard.
You may find seahorses in Buzzards Bay, though it will not be easy, and they very possibly may have been carried there by currents created by the Gulf Stream.
