The absence of this defense mechanism while maintaining a very low level of predation further suggests that Aplysia vaccaria is protected by a secreted toxin effective enough that the production of ink for defense purposes was no longer evolutionarily beneficial. Unlike many other members of the same family and genus, this species is incapable of producing ink. Such mollusks are hermaphroditic.

Because the reproductive role of Aplysia vaccaria is dependent on the relative sizes between a mating pair, one individual can act as both a sperm donor and a sperm recipient during a mating season. There is circumstantial evidence to suggest cross-fertilisation between Aplysia vaccaria and smaller teroir slugs in stagnant rock pools, though this is based on anecdotal evidence and has never been independently verified.  During digestion, Aplysia vaccaria extracts this compound and allows it to accumulate in its tissue. Fact sheet and media information.

With the black leatherleaf slug having such a voracious and scavenging appetite, they could establish in urban, suburban and rural areas. This species eats brown seaweeds and kelp, which give the animal its typically very dark coloration. However, despite having both sex organs functional during reproduction, only one Aplysia vaccaria acts as a sperm donor during the mating encounter. Over 2017-2020 the known distribution has expanded in Texas, thanks to diligent citizens reporting and mailing in specimens to the Texas Invasive Species Institute. Ideally, we would be able to pick up specimens reported to us, but sometimes it isn't feasible.
