Abstract

The cnidome of the scleractinian cold-water coral (Linnaeus, 1758, syn. ) was described by Carlgren in 1940. Due to a renewed interest in the cnidae of specifically comparisons of adult and larval cnidae and their functions, we now redescribe the cnidome from material collected at the Tisler reef in Norway, close to Carlgren's collection site at Saekken (Sweden). Cnidae from column, tentacles, actinopharynx, mesenterial filaments and acontia were investigated. Fresh tissue preparations were compared to histological preparations of decalcified polyps to verify the presence of cnidocysts and secretory cells, and their composition and organization within tissues. The cnidome included microbasic b-mastigophores, microbasic and mesobasic p-mastigophores, holotrichous isorhizas and spirocysts. The nematocyst type cnidae (b-, p-mastigophores, isorhizas) appeared in different size classes with different distributions within the tissue. Spirocysts were highly variable in shape and size, without distinct size classes. In addition, developing stages of cnidae were documented, with new observations on the succession of p-mastigophore shaft development. The present observations were in general congruent with the cnidocyst descriptions from made by Carlgren; however, a tiny cnida, possibly of isorhiza type, has been added. Finally, the use of the term acontia is discussed.

摘要

石珊瑚目冷水珊瑚(林奈,1758年,同物异名)的刺丝囊由卡尔格伦于1940年进行了描述。由于对刺丝囊重新产生兴趣,特别是对成体和幼体刺丝囊及其功能进行比较,我们现在根据在挪威蒂斯勒礁采集的材料重新描述刺丝囊,该地点靠近卡尔格伦在瑞典塞肯的采集点。对来自柱体、触手、辐管、肠系膜丝和刺丝腔的刺丝囊进行了研究。将新鲜组织标本与脱钙息肉的组织学标本进行比较,以验证刺丝囊和分泌细胞的存在及其在组织内的组成和组织结构。刺丝囊包括微基b型鞭毛刺细胞、微基和中基p型鞭毛刺细胞、全毛等刺胞和螺旋刺丝囊。刺丝囊类型的刺细胞(b型、p型鞭毛刺细胞、等刺胞)在组织内呈现出不同大小等级和不同分布。螺旋刺丝囊在形状和大小上高度可变,没有明显的大小等级。此外,记录了刺丝囊的发育阶段,并对p型鞭毛刺细胞轴的发育顺序有了新的观察结果。目前的观察结果总体上与卡尔格伦所作的刺丝囊描述一致;然而,增加了一种可能是等刺胞类型的微小刺丝囊。最后,讨论了“刺丝腔”一词的使用。
