salabay o bokya

Salabay, Bokya, Budol o Bantól[1], mga hayop na nalangoy ngan mali in payong o bagtingan na gulaman ngan may tentacles. Sakob ini san Phylum Cnidaria.

Nahihiagian an salabay sa natanan na kadagatan, mapahibababaw o hilarum. Mayaon pipira na bokya na mahihiagian sa matapsi na tubig. Komon an salabay sa mga baybay sa bug'os na kalibutan. Nagkinalangoy na an salabay sa kadagatan sin diri mahabubo 500 milyones katuig.[2] ug posible 700 milyones katuig o malahos pa, ngan sira an pinakaagap na multi-organ na hayop.[3]

Sakob san Medusozoa an salabay, an clade san mga cnidarian na diri gin'api an Anthozoa (hal., coral ngan anemone). Nagsusuwestyon ini na an porma-medusa nag-evolve tikang sa polyp.[4]

An upat na mayor na klase san medusozoa na Cnidaria amo an:

  • Scyphozoa,an ginsesering na ungud na salabay.
  • Cubozoa, ( o bokya) korte kahon an bell, ngan may velarium na naayuda para mas malaksi lumangoy.
  • Hydrozoa
  • Staurozoa, (stalked jellyfish) wara ini polyp stage

mga hayop na pirmi naaalahan na medusa na salabay.

Malahos 200 na specie may'ada an Scyphozoa, harani 50 na specie may'ada an Staurozoa, 20 specie san Cubozoa, ngan an Hydrozoa maabot 1000–1500 na specie na nagproprodyus medusae (ngan mas damo pa na hydrozoa an diri na prodyus medusae).[6][7]

A comprehensive morphological cladistic analysis by Schuchert (1993) supports the basal position of Anthozoa with the Scyphozoa and Cubozoa being more closely related to each other than to Hydrozoa. Morphological, mtDNA, and 18S rDNA data separately and together also support the basal position of Anthozoa but do not resolve the relationships among Scyphozoa, Cubozoa and Hydrozoa (Bridge et al. 1995).
