(Last Updated On: April 25, 2021)

Long-snouted seahorse, scientific name Hippocampus guttulatus, is the spiny seahorse, and a marine fish belonging to the family Syngnathidae, native from the northeast Atlantic, together with the Mediterranean.

Distribution

Eastern Atlantic: the British Isles and the Netherlands to Morocco, Canary Islands, Madeira, and the Azores, together with the Mediterranean.

Although morphologically smaller than specimens from different areas, current genetic information confirms that specimens from the Black Sea space the truth is long-snouted seahorses. International commerce is monitored by a licensing system and a minimum size of 10 cm applies.

Long-Snouted Seahorse Description

The long-snouted seahorse is a small-sized fish that may attain the most size of 21.5 cm however the average size is more or much less 12 cm.

The body is slender, the snout is long and the tail is prehensile. Its head and dorsal ridge have usually some more or much less long and quite a few dermal filaments which will be easy or bifid.

Its color ranges from darkish green to totally different variants of brown to yellow, the body is commonly speckled with small white dots.

Dorsal spines (total): 0; Dorsal smooth rays (total): 17-20. Description (based mostly on 46 specimens): Adult height: 8.5-18.0cm. Rings: 11 + 37-39 (35-40). Snout size: 2.3-2.8 in head size.

Dorsal fin rays: 19-20 (17-20) masking 2+1 rings. Pectoral fin rays: 16-18. Coronet: small however distinct, with 5 rounded knobs or blunt factors; horizontal plate in front of a coronet as high as coronet itself, with a more or much less distinguished backbone at its front edge; coronet not joined easily to the neck.

Spines: medium to well-developed with blunt ideas. Other distinctive characters: distinguished rounded eye spines; usually with a mane of thick skin fronds on neck and head.

Color pattern: from darkish green to brown; distinguished white spots on body (usually with a darkish ring round them) which are inclined to coalesce into horizontal wavy lines103; could also be variously mottled or with pale ‘saddles’ throughout the dorsolateral floor.

Long-Snouted Seahorse Habitat

The long-snouted seahorse is widespread all through the temperate waters of the eastern Atlantic Ocean from the south coast of the United Kingdom to the Netherlands and south to Morocco, together with the Canary Islands, the Azores, and Madeira, and the Mediterranean Sea.

This seahorse likes shallow coastal waters from 1 to twenty m deep. It happens shut by Posidonia and eelgrass meadows or in blended habitats with sandy backside and rocks with algae.

Long-Snouted Seahorse Biology

The long-snouted seahorse has a carnivorous diet and feeds on small crustaceans, larvae, fish eggs, and different planktonic organisms. It is ovoviviparous and it’s the male who broods the eggs in its ventral brood pouch.

The latter consists of villi wealthy in capillaries that encompass every fertilized egg making a form of placenta supplying the embryos. When absolutely grown, pups might be expelled from the pocket and evolve in full autonomy.

Commonly known as Hippocampus ramulosus. Occurs largely in shallow inshore waters together with littoral lagoons amongst algae and eelgrass (Zostera or Posidonia), or amongst rocks and in gravel bottoms.

Juveniles have been noticed to recruit to vegetated habitats at 8.8- 10.4 cm size. Adults (from 12.5 cm size) seem to keep up very restricted house ranges (19.9 ± 12.4 m2) over a number of years making restricted each day actions.

May transfer to deeper waters throughout winter. Like different seahorse species, adult dispersals over massive distances are in all probability attributable to sturdy wave action and currents throughout storms or when it anchors itself to floating particles.

Is thought to live for 4-7 years. Because of its early age at maturity, fast growth rate, brief era time, and a number of breeding cycles throughout every spawning season, resilience is regarded as high.

However, in tropical areas the place seagrass beds are often exploited for different species of seahorses for aquarium commerce, conventional drugs, and so forth., populations have been shortly eradicated. Can be maintained in an aquarium environment if educated to feed on lifeless animals. Length kind OT refers to height (= TL – head size).

Long-Snouted Seahorse Reproduction

Ovoviviparous. During the mating season, mature women and men have been noticed to vary the hue, i.e., grow to be brighter, when courting. Female deposits her eggs on the brood pouch of the male which is discovered underneath the tail.

Gestation often lasts 21 days and brood sizes of as much as 581 have been reported. Young are expelled from the pouch measuring 1.5 cm after 3 weeks of incubation. Size at birth ranges from 0.6-1.4 cm in size. Newly hatched younger are planktonic for no less than 8 weeks.

Long-Snouted Seahorse Conservation

The long-snouted seahorse is comparatively uncommon and restricted knowledge exists on its inhabitants and in regards to the quantity and the impression of commerce for the standard Chinese drugs and for the aquarium, thus the species is taken into account as “Data Deficient” on the IUCN Red List.

Internationally, it is usually listed in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) which means it’s on the record of species not essentially threatened with extinction, however wherein commerce have to be managed so as to keep away from utilization incompatible with their survival.
