Sargassum Fish

Sargassum Fish

Histrio histrio

Size: to 6"

Habitat: wherever the current takes them

Notes: Sargassum fishes are found in drifting clumps of Sargassum weed. They are certainly one of the most bizarre fishes you may encounter. Their closest relatives are deep-sea anglerfishes and the local Goosefish. The paired fins are used exactly like arms and legs, and the Sargassum fish is a clumsy and reluctant swimmer. In fact, the pectoral (arm) fins can be folded over below the elbow, giving the fish an opposable grasp much like our own hands!

Building artificial reefs is a lot more than just throwing junk in the ocean. The material needs to meet standards for cleanness and suitability, and it needs to end up where it is intended, and not somewhere else. Concrete and stone are easy, as they go straight down wherever they are dropped.
