This takes no more than a few microseconds . After penetration , the toxic content of the nematocyst is injected into the target . This discharge takes no more than a few microseconds , and is able to reach accelerations of about 40,000 g. Recent research suggests the process to occur as fast as 700 nanoseconds , thus reaching an acceleration of up to 5,410,000 g. After penetration , the toxic content of the nematocyst is injected into the target organism .
