Although the Sargassum Fish is capable of swimming quite rapidly, it often crawls through the Sargassum Weed, using its pectoral fins like arms. A good reef dweller, the Sargassum enjoys perching on coral ledges and requires a tank of at least 30 gallons. We investigated, using microcosm experiments, predator-prey relationships of symbionts within sargassum communities. They range from the New England South all the way to Brazil. Since 2011, blooms of Sargassum have wreaked havoc on tropical shores. The unique appearance of the fish features stalked, grasping, limb-like pectoral fins with small gill openings behind the base, a trapdoor-like mouth high on the head, and a “fishing lure” on the snout.

When waves of sargassum - a type of seaweed - washed up on Eastern Caribbean shores seven years ago, people hoped it was a one-off. When sargassum loses its buoyancy, it sinks to the seafloor, providing energy in the form of carbon and also food sources to fishes and invertebrates in the deep sea. Scientists have some theories about the invasion of the sargassum seaweeds in the Caribbean. In courtship the male closely follows the female, rushing to the surface to spawn. The sargassum fish is a small ambush predator (growing only to 20 cm in length) that gets its common name from the habitat in which it lives – sargassum algae beds that float on the ocean’s surface. SAFMC Second Revised Final: Fishery Plan for Pelagic Sargassum Habitat of the South Atlantic Region – The final Fishery Management Plan for Pelagic Sargassum Habitat in the South Atlantic Region was approved in 2003 and implemented strict restrictions on commercial harvest of this important fish habitat.

Small dolphin fish live very close to the Sargassum, and as they become larger, they patrol in schools underneath the weed lines. The body and the fins are covered with many weed-like protrusions, but other than these, the skin is smooth without dermal spines. Most of these fishes are in juvenile stages and use the habitat for feeding while taking advantage of it to hide from predators.
