Eschscholtz, 1825
Tricornuate tentilla consisting of a coiled cnidoband enveloped in an involucrum, plus a terminal vesicle and 2 lateral processes. When the lateral processes of the tentillum are relaxed, the whole structure has the semblance of a copepod. Purcell (1980) has suggested that this is a form of aggressive mimicry.
