Go to Species Summary

Nerophis ophidion   (Linnaeus, 1758)
Family:	Syngnathidae (Pipefishes and seahorses) , subfamily: Syngnathinae			picture (Neoph_u0.jpg) by Hernández-González, C.L.
Order:	Syngnathiformes  (pipefishes and seahorses)
Class:	Actinopterygii (ray-finned fishes)
FishBase name:	Straightnose pipefish
Max. size:	29.0 cm TL (male/unsexed; Ref. 2058); 30 cm TL (female)
Environment:	demersal ; depth range 2 - 15 m
Climate:	temperate; 63°N - 30°N
Global Importance:	fisheries: of no interest
Resilience:	High, minimum population doubling time less than 15 months (K=1.05)
Distribution:	Eastern Atlantic: Norway to Morocco (excluding region from Denmark to Netherlands), also throughout the Mediterranean and the Black Sea.
Diagnosis:	Anal and pectoral fin absent. Anal opening below front end of the dorsal fin, 28-33 body rings. Has a strait snout (Ref. 35388).
Biology:	Inhabit algal zone or eel-grass (Zostera) (Ref. 6733). Adults spawn in May - August . Feed on small crustaceans and fish fry (Ref. 35388). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Consistent paternity is ensured despite brooding of embryos on the outside of the male's body. Events of cuckoldry by sneaker males is ruled out through genetic paternity analyses based on molecular markers (Ref. 81011). Each male carries eggs from a single female but females may deposit eggs on several brooding pouches (Ref. 81011)
Threatened:	Not Evaluated, see IUCN Red List  , (Ref. 36508)
