'''Cucut ronggeng''' (''Eusphyra blochii'') adalah sejenis [[cucut martil]], [[
== Pengenalan ==
Ciri utama cucut ronggeng adalah ‘martil’ di kepalanya (disebut "cephalofoil") yang sempit dan panjang menyamping, membedakannya dari jenis-jenis cucut martil yang lain.
Cucut yang tak seberapa besar;
== Agihan dan habitat ==
Cucut ronggeng hidup di laut-laut dangkal di [[paparan benua]] dan laut pedalaman wilayah Indo-Pasifik Barat, mulai dari [[Teluk Persia]] di barat hingga [[Filipina]];

The cephalofoil of the winghead shark is so large as to be almost unwieldy, while the placement of the nostrils and the [[ampullae of Lorenzini]] are wider than in non-hammerhead sharks (albeit more medial than in other hammerhead sharks). Along with its basal position in hammerhead phylogeny, this lends support to the idea that this structure originally evolved for a sensory, rather than hydrodynamic, function.<ref name="martin"/> The winghead shark feeds mainly on small [[teleost]] fishes, but also takes [[crustacean]]s and [[cephalopod]]s.<ref name="fishbase"/>
Like other hammerhead sharks, the winghead shark is [[viviparous]] with the [[embryo]]s nourished by a [[yolk sac]] [[placenta]]. Off [[Bombay]], the young are birthed just before the [[monsoon]] season in April and May and mating takes place during the monsoon from June to August, suggesting a [[gestation period]] of eight months.<ref name="compagno"/> Off [[Australia]], the females give birth in February and March, after a gestation period of 10–11 months.<ref name="stevens and lyle">{{cite journal |author=Stevens, J.D. and Lyle, J.M. |title=Biology of three hammerhead sharks (''Eusphyra blochii'', ''Sphyrna mokarran'' and ''S. lewini'') from Northern Australia |journal=Australian Journal of Marine and Freshwater Research |volume=40 |issue=2 |pages=129–146 |year=1989 |accessdate=2008-10-19 |doi=10.1071/MF9890129}}</ref> Litters number 6 to 25 pups,<ref name="fishbase"/> with the young measuring 32–45 cm at birth.<ref name="compagno"/> Females reproduce every year.<ref name="stevens and lyle"/> Maturation occurs at around 110 cm.<ref name="iucn"/>
==Taxonomy and phylogeny==
[[Georges Cuvier]] first described a specimen of the winghead shark in 1817, as a footnote to his account of ''Squalus zygaena'' (=''Sphyrna zygaena'', the [[smooth hammerhead]]). Although his citation was not a proper [[binomial name]], Valenciennes interpreted it as ''Zygaena Blochii nobis'' when he described and illustrated the winghead shark in detail in 1822.<ref name="compagno">Compagno, Leonard J. V. (1984) ''Sharks of the World: An Annotated and Illustrated Catalogue of Shark Species Known to Date''. [[Rome]]: [[Food and Agricultural Organization]]. ISBN 92-5-101384-5.</ref> Compagno (1979, 1988) elevated the winghead shark to its own genus, ''Eusphyra'', although this was disputed by Dingerkus (1986) on the grounds that it made the genus ''[[Sphyrna]]'' [[paraphyletic]]. Since then, the winghead shark has been listed under its own genus or as a subgenus of ''Sphyrna'' in various sources.<ref name="martin"/>
