Longsnout Seahorse

Hippocampus reidi

The Longsnout Seahorse (Hippocampus reidi) is a slender western Atlantic seahorse with a very long snout and prehensile tail. It lives among seagrass, macroalgae, mangroves, and floating debris, and is usually observed clinging rather than actively swimming.

Identification points

Very long, narrow snout compared with head size
Slender body with a tall coronet and segmented ring-like armor
Prehensile tail used to grasp seagrass or algae

Habitat

Shallow tropical to subtropical coastal waters, especially seagrass beds, Sargassum, mangrove roots, and sheltered reefs or debris lines; commonly in low-flow areas where it can anchor with its tail.

Bait notes

Not a target sport fish and should generally not be hooked. If observed in the wild for photography, use no bait; if incidentally encountered, avoid live baiting and handle as little as possible.

Behavior

Ambush feeder that eats tiny crustaceans and other planktonic prey by suction through its long snout. It is a weak swimmer, spends much of its time stationary, and males brood the embryos in a pouch.

Caution

Often vulnerable to collection and habitat loss; check local protections, as seahorses may be regulated or protected in some areas. Handle carefully because the tail and skin are delicate, and avoid removing from water.

Fishing notes

Best treated as a release-only observation species. If accidentally caught, keep it submerged, support the body and tail gently, and release immediately; do not use gaffs or grip tools.
