Thanks Jackie & Glen,
One feature I can't see described in the literature is the presence of the cnidosac, the sac at the tip of the cerata of cnidarian feeding aeolids in which nematocysts are stored. I can't see any sign of it in your photos but it could be small and hidden beneath the white tip. If it is absent, or very reduced in size, it would be another sign that these animals do not feed on cnidarians
Best wishes
