Further, two distinct types of otocyst can be recognized in the Hydro medusae; that of the Leptolinae, in which the entire organ is ectodermal, concrement-cells and all, and the organ is not a tentaculocyst; and that of the Trachylinae, in which the organ is a tentaculocyst, and the concrement-cells are endodermal, derived from the endoderm of the modified tentacle, while the rest of the organ is ectodermal.
- Tentaculocyst (statorhabd) ous with the endoderm of Cunina solnzaris.
- Tentaculocyst of Cunina lati- their simplest form as a ventris.
- Simple tentaculocyst of Rlzopaloocellus be on the nema velatum.
A tentaculocyst (" colleto-cysto- o, phore" or " marginal anchor ") se, seen from the subumbral side.
Each nerve-centre controls its own antimere or segment of the body, receiving sensory impressions from the tentaculocyst and innervating its special subdivision of the muscular system.
Two types of tentaculocyst must FIG.
- Tentaculocyst of Charyb- of adherence rather than to daea marsupialis, seen from the have the function of senseright side.
The ephyra has a flat, disk-shaped body, with eight marginal lobes (four perradial, four interradial); a tentaculocyst is lodged in a deep notch at the apex of each lobe.
