The myonemes of these cells attach to the mesoglea and to the exterior perisarc. |
|
These cells are anchored to the perisarc and pull on the mesoglea, which becomes thickened. |
|
Here, a marine hydroid perisarc of Aglaophenia latirostris was investigated to understand how nature designs a stiff, tough and lightweight sheathing structure. |
|
No annulations on the perisarc were seen and no gonophores were observed. |
