Summary

It is reported that Ca2+-induced discharge of in situ nematocytes of acontia ofCalliactis parasitica can occur by cell-to-cell transmission along the acontial filament at a speed that averages 9.8·10−3 cm−1. The discharge is preceded by protrusion of nematocytes that proceeds along the acontium at a slightly higher speed.
