25 October 2024 – CAPE COD, MA – Every summer hundreds of tropical fish species ride the Gulf Stream from the Caribbean Sea to the Atlantic Ocean, and jumps off at Cape Cod. A few weeks ago a rare Gulf Stream orphan, a Blue Angelfish, only two months old, sought refuge hundreds of miles from home at Orleans' oyster grants in Pleasant Bay. It is the northernmost Angelfish recorded to date. We know our waters are warming, but what does the appearance of tropical species mean for us and our coastal ecosystems?
