Abstract
Hrskavičnjače (Chondrichtyes) su evolucijski stari razred koji se dijeli na dva podrazreda:
prečnouste (Elasmobranchii) u koje spadaju morski psi (Selachii) i raže (Batoidea) te cjeloglavke
(Holocephali). Hrskavičnjače su ime dobile po činjenici da njihov kostur nije koštan, već je
izgrađen od hrskavice. Jadransko more, kao dio Mediterana, se zbog svojih posebnih karakteristika
u dubini, temperaturi i salinitetu čini kao idealno mjesto za biološku raznolikost morske faune, pa
tako i hrskavičnjača. Tako su u Jadranu zabilježene čak 54 vrste hrskavičnjača te su u ovom
preglednom radu kratko opisane karakteristike svake vrste. Također, zbog svoje negativne
popularnosti, kratko je spomenuta i moguća opasnost koju predstavljaju za ljude.Chondrichtyes are an evolutionary class that is divided into two subclasses: Elasmobranchii that
contains Selachii (sharks) and Batoidea (rays) groups, and Holocephali subclass. Chondrichtyes
are named after the fact that their skeleton is not made of bone, but rather cartilage. Adriatic Sea,
part of Mediterranean sea, due to its special characteristics in depth, temperature, and salinity,
makes an ideal place for the biodiversity of marine fauna, especially cartilaginous fish. There are
54 Chondrichtyes species noted in Adriatic Sea, and in this review the characteristics of each
species are briefly described. Also, due to its negative popularity, it is briefly summarized their
potential danger they might pose to people
