| Abstract: | ![]()
The fishing tentacles of Physalia physalis (Portuguese man-of-war) adhere to prey and human victims by the penetration of a barbed tubule connected to an intracellular nematocyst. The nematocyst is surrounded by a fibrillar system of microtubules and microfilaments that terminate in hemidesmosomal processes which anchor the nematocyst to the acellular mesoglea of the tentacle. |
