Hippocampus denise in Indonesia
Denise's pygmy seahorse

Hippocampus denise Lourie & Randall, 2003
Family:	Syngnathidae (Pipefishes and seahorses) , subfamily: Hippocampinae	picture (Hiden_u4.jpg) by Brett, O.J.
Order:	Syngnathiformes (pipefishes and seahorses)
Class:	Actinopterygii (ray-finned fishes)
FishBase name:	Denise's pygmy seahorse
Max. size:	2.2 cm SL (male/unsexed; Ref. 47053); 2.4 cm SL (female)
Environment:	reef-associated ; depth range 13 - 90 m
Climate:	tropical
Global Importance:
Resilience:	High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.)
Distribution:	Western Pacific: apparently more widespread than Indonesia, Vanuatu and Palau. Observed from Malaysia, Solomon Islands and Pohn Pei, Micronesia. International trade is monitored through a licensing system (CITES II, since 5.15.04).
Diagnosis:	Dorsal soft rays (total): 14-14. Color in life plain orange with slightly darker rings around tail; when preserved, pale orange with tiny dark brown flecks on the nape of the neck and all over in some specimens. Diminutive in size. Anal fin small or absent. Rings on trunk 12; on tail 28-29. Body fleshy with inferior and ventral trunk ridges reduced to separated cross-shaped spicules embedded in the skin. Nuchal plate rounded without a raised coronet. Snout length ca. 30% in HL. Head depth ca. 50% in HL. No spines above the eye. Trunk depth (between the 9th and 10th trunk rings) ca. 7% in SL (female) and 10-15% in SL (male). The angles of certain body ridges sometimes developed into rounded tubercles (distinctly fewer and less developed compared with H. bargibanti) (Ref. 47053).
Biology:	Lives in association with gorgonian seafans (Annella reticulata, Muricella sp., and Echinogorgia sp.). Master of camouflage, with their coloration and body ornamentation in the form of tubercles, can match the stems and polyps of their gorgonian hosts (Ref. 47053). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205)
Threatened:	Data deficient, see IUCN Red List , (Ref. 36508)
Dangerous:	harmless
