Inking by marine molluscs such as sea hares, cuttlefish, squid, and octopuses is a striking behavior that is ideal for neuroecological explorations. While inking is generally thought to be used in active defense against predators, experimental evidence for this view is either scant or lacks mechanistic explanations. Does ink act through the visual or chemical modality? If inking is a chemical defense, how does it function and how does it affect the chemosensory systems of predators? Does it… 

Chemical defenses of Aplysia californica and sensory processing by predatory fishes

TLDR
This dissertation argues that the study of chemical defenses allows for more questions about detection of relevant deterrents and interactions between predators and prey at the individual and population levels, and lays the foundation for how a diet-derived photopigment is adapted by a species to protect itself from predators by stimulating their chemosensory systems.

Defense through sensory inactivation: sea hare ink reduces sensory and motor responses of spiny lobsters to food odors

TLDR
Results indicate that opaline reduces the output of chemosensors by physically blocking reception of and response to food odors, and this has an impact on motor responses of lobsters.

TLDR
This review summarizes the current knowledge of cephalopod ink and discusses the chemical components of ink, with a focus on the best known of these—melanin and the biochemical pathways involved in its production.

Defensive Responses of Cuttlefish to Different

TLDR
It is suggested that cuttlefish may vary their behavior in the presence of different teleost predators: cryptic behaviors may be more important inThe presence of active searching predators (e.g., bluefish), while conspicuous movements such as swimming in the water column and startle displays might be more prevalent with relatively sedentary, bottom associated predators.

Ink From Longfin Inshore Squid, Doryteuthis pealeii, as a Chemical and Visual Defense Against Two Predatory Fishes, Summer Flounder, Paralichthys dentatus, and Sea Catfish, Ariopsis felis

TLDR
This work finds that ink from longfin inshore squid affected the approach phase of predation by summer flounder, primarily through its visual effects, and provides the basis for a comparative approach to identify deterrent molecules from inking cephalopods and to examine neural mechanisms whereby these chemicals affect behavior of fish, using the sea catfish as a chemosensory model.

Chemical Composition of Inks of Diverse Marine Molluscs Suggests Convergent Chemical Defenses

TLDR
The hypothesis that inking molluscs have the potential to use sensory disruption and/or phagomimicry as a chemical defense is supported.

The seahare Aplysia spp. extracts many of its defensive chemicals from its red seaweed diet, including its purple ink, which is an effective deterrent against predators such as anemones and crabs. It

Sea Hares Use Novel Antipredatory Chemical Defenses

Packaging of chemicals in the defensive secretory glands of the sea hare Aplysia californica

TLDR
It is concluded that lysine in opaline is the primary natural substrate for escapin in ink, which allows for the generation of bioactive defensive compounds from innocuous precursors at the precise time they are needed.

Ink secretion by the marine snail Aplysia californica enhances its ability to escape from a natural predator

TLDR
The survival value of ink and the snail's aversion to it supports ink's proposed anti-predator function, thus avoiding potential sites of ongoing predation.

Acidity enhances the effectiveness of active chemical defensive secretions of sea hares, Aplysia californica, against spiny lobsters, Panulirus interruptus

TLDR
It is shown here that ink and opaline are highly acidic, both having a pH of ∼5.5, and this suggests that acidity enhances the phagomimetic chemical defense of sea hares.

To avoid or deter: interactions among defensive and escape strategies in sabellid worms

TLDR
Most species utilize a combination of predator avoidance and deterrence strategies, but more deterrent populations of species utilized avoidance less, and most species allocated defenses to tissues that were most exposed to predation.

Distastefulness as a defense mechanism in Aplysia brasiliana (Mollusca: Gastropoda)

TLDR
Ink gland, gill, and epidermal portions are shown to be significantly more distasteful than other portions, even the midgut and opaline glands, sites of compounds which can be toxic when injected.
