<div class=""abs_img""> <img src=""[disp_template_path]/JRM/abst-image/00270005/14.jpg"" width=""300"" /> Injection into the starfish</div> We have been studying and developing an underwater robot for coral reef conservation. This paper describes the development of an acetic acid injection device mounted on an underwater robot for use in exterminating crown-of-thorns starfish that damage corals. First, we outlined the ecology and morphology of the crown-of-thorns starfish to identify requirements for the acetic acid injection device. Based on the requirements identified, we designed and prototyped an acetic acid injection device to be installed on an underwater robot. Next, we installed the developed injection device on a remotely operated vehicle and injected acetic acid into crown-of-thorns starfish under water. We describe the effectiveness of this acetic acid injection device for exterminating crown-of-thorns starfish. The experimental results prove that the developed acetic acid injection device can inject acetic acid into crown-of-thorns starfish just as intended, and that an underwater robot installed with such device can be used effectively to aid in the extermination of crown-of-thorns starfish. </span>

Schumacher and Halbsguth first demonstrated ectodesmata as pores or channels in the epidermal cell walls in haustoria of Cuscuta odorata L. by light microscopy in tissues fixed in a sublimate fixative (30% ethyl alcohol, 30 ml:glacial acetic acid, 10 ml: 65% nitric acid, 1 ml: 40% formaldehyde, 5 ml: oxalic acid, 2 g: mecuric chloride to saturation 2-3 g). Other workers have published electron micrographs of structures transversing the outer epidermal cell in thin sections of plant leaves that have been interpreted as ectodesmata. Such structures are evident following treatment with Hg++ or Ag+ salts and are only rarely observed by electron microscopy. If ectodesmata exist without such treatment, and are not artefacts, they would afford natural pathways of entry for applied foliar solutions and plant viruses.
