Polymorphism in siphonophora pdf

The following points highlight the two main types of polymorphic variabilities in Siphonophora. 1. Modifications of the Polyp: A. Gastrozooids or Trophozooids Highly modified polymorphism: In order Siphonophora, such as Diphyes, Halistemmia,. Stephalia and Physalia, zooids are so much modified that they appear Gonophore: Bearing gonads Male: sperms Female: ova Notable polymorphic colonies: 1.Siphonophora 2.Chondrophora 1. Siphonophora Physalia Pneumatophore: apex, Siphonophora are very polymorph members of the cnidarian Superclass Hydrozoa.
