Sažetak
More than 3000 Hydrozoa and Scyphozoa species have the sessile polyp stage. Increasing attention has been paid to this stage partly due to the damage or disaster caused by hydropolyp fouling or jellyfish blooms. We studied how hydro- and scyphopolyps keep adhering to substrata, a prerequisite to all aspects of their life, using quantitative cellular maceration method and qualitative histological and ultrastructural methods. We choose more than 10 typical coastal Hydrozoa or Scyphozoa species with standard hydrorhiza or reduced pedal disks, cut them into free fragments or remove their pedal disks in the field or laboratory conditions, and find that they are able to regenerate new attaching structure and fulfill reattachment within 48 hours, with a success range from 2% to 100%. We thus conclude that polyps have a strong ability to maintain adhesion, and the variation their adhesion structure show a certain extent of evolution. We further find that nematocytes and glandular-epithelial cells tend to decline significantly during reattachment, while neutral or acidic glycoprotein and immature perisarc granules secreted by glandular-epithelial cells emerged in clusters. This is the first insight in the maintenance of adhesion pathway in hydro- and scyphopolyps These results help to better understand the colonization and asexual dispersal and provide target cell types to test potential effective intrinsic and extrinsic cues of adhesion in hydro- and scyphopolyps. These results could also provide valuable reference for Anthozoa and Cubozoa.
