Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 17-20. Description (based on 46 specimens): Adult height: 8.5-18.0cm. Rings: 11 + 37-39 (35-40). Snout length: 2.3-2.8 in head length. Dorsal fin rays: 19-20 (17-20) covering 2+1 rings. Pectoral fin rays: 16-18. Coronet: small but distinct, with 5 rounded knobs or blunt points; horizontal plate in front of coronet as high as coronet itself, with a more or less prominent spine at its front edge; coronet not joined smoothly to neck. Spines: medium to well-developed with blunt tips. Other distinctive characters: prominent rounded eye spines; often with a mane of thick skin fronds on neck and head. Color pattern: from dark green to brown (Refs. 52034, 89230); prominent white spots on body (often with a dark ring around them) which tend to coalesce into horizontal wavy lines103; may be variously mottled or with pale ‘saddles’ across dorsolateral surface.

Biologie     Glossaire (ex. epibenthic)

Commonly referred to as Hippocampus ramulosus. Occurs mostly in shallow inshore waters including littoral lagoons (Ref. 9937) among algae and eel grass (Zostera or Posidonia), or among rocks and in gravel bottoms (Ref. 52034). Juveniles were observed to recruit to vegetated habitats at 8.8- 10.4 cm length (Ref. 79902). Adults (from 12.5 cm length) appear to maintain very restricted home ranges (19.9 ± 12.4 m2) over multiple years making limited daily movements. (Ref. 79902). May move to deeper waters during winter (Ref. 53712). Like other seahorse species, adult dispersals over large distances is probably caused by strong wave action and currents during storms or when it anchors itself to floating debris (Ref. 52034). Is thought to live for 4-7 years (Ref. 79902). Because of its early age at maturity, rapid growth rate, short generation time and multiple breeding cycles during each spawning season, resilience is thought to be high (Ref. 88171). However, in tropical areas where seagrass beds are regularly exploited for other species of seahorses for the aquarium trade, traditional medicine, etc., populations have been quickly eradicated (Ref. 89253). Can be maintained in an aquarium environment if trained to feed on dead animals (Ref. 88171). Length type OT refers to height (= TL - head length), Ref. 30915.

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Ovoviviparous. During the mating season, mature males and females have been observed to change hue, i.e., become brighter, when courting (Refs. 52034, 89259). Female deposits her eggs on the brood pouch of the male which is found under the tail (Ref. 205). Gestation usually lasts 21 days (Ref. 89322) and brood sizes up to 581 have been reported (Refs. 53712, 79902, 89322). 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 length (Ref. 79902). Newly hatched young are planktonic for at least 8 weeks (Ref. 53712).
