Long snouted seahorse (Hippocampus guttulatus)
|Researched by||Anna Neish||Refereed by||Admin|
|Other common names||-||Synonyms||Hippocampus ramulosus Cuvier, 1829|
Hippocampus guttulatus can be up to 15 cm in length and has a long snout. The fleshy protuberances on the back of the neck, from the head to dorsal fin, give an appearance of a 'mane'. It can be coloured from greenish-yellow through to reddish-brown and often mimics the colour of associated vegetation. It is speckled with bluish-white spots and flecks and its body rings carry bony tubercles giving it an angular, knobbly appearance.
Recorded distribution in Britain and Ireland
Recorded from the south coast of England and south west coasts of Wales.
Recorded from the Netherlands, along the east Atlantic coast of Europe south to Morocco and Senegal, and from Italy, Malta, Croatia, Greece and Cyprus in the Mediterranean.
Present in shallow waters, especially amongst algae and seagrasses, clinging by the tail or swimming upright.
- Body up to 15 cm in length.
- Long snout, more than one third the length of the head.
- Fleshy strands, mane from head to dorsal fin.
- Pectoral fin has 15-18 rays.
- Dorsal fin has 18-21 rays.

Other common names include the 'spiny seahorse' or the 'many branched seahorse'. The long snouted seahorse is one of two species of seahorses found in the British Isles; the other is Hippocampus hippocampus, which can be distinguished by a shorter snout and the lack of elongated protuberances along the back of the neck. Their distribution around the British Isles has been recently revised by the British Seahorse Survey (Garrick-Maidment & Jones, 2004).
