Ink secretion by the marine snail Aplysia californica enhances its ability to escape from a natural predator
Abstract1.Aplysia californica incorporates toxins and pigments from its red seaweed diet into its body and ink, purportedly as a defense against predation. We tested ink's potential defensiveExpand

Palatability and Chemical Defense of Phragmites australis to the Marsh Periwinkle Snail Littoraria irrorata
Coastal marsh habitats are impacted by many disturbances, including habitat destruction, pollution, and the introduction of invasive species. The common reed, Phragmites australis, has beenExpand

Chemical Composition of Inks of Diverse Marine Molluscs Suggests Convergent Chemical Defenses
Some marine molluscs, notably sea hares, cuttlefish, squid, and octopus, release ink when attacked by predators. The sea hare Aplysia californica releases secretions from the ink gland and opalineExpand

Palatability and defense of some tropical infaunal worms: alkylpyrrole sulfamates as deterrents to fish feeding
Numerous studies have investigated chemical defenses among sessile species growing on hard substrates, but few have addressed this for mobile species in soft-sediment communities. We investigated theExpand

Sea Hares Use Novel Antipredatory Chemical Defenses
Numerous studies have demonstrated that chemical defenses protect prey from predation and have often assumed that these defenses function by repelling predators. Surprisingly, few have investigatedExpand

Do brominated natural products defend marine worms from consumers? Some do, most don't
Worms and other marine invertebrates living in soft sediments commonly produce brominated natural products that have been hypothesized to function as defenses against consumers, but this hypothesisExpand

Multiple components in ink of the sea hare Aplysia californica are aversive to the sea anemone Anthopleura sola
Abstract Sea hares of the genus Aplysia rely on an array of behavioral and chemical defenses, including the release of ink and opaline, to protect themselves from predation. While many studies haveExpand

Isolation and Structural Elucidation of Novel Mycosporine‐Like Amino Acids as Alarm Cues in the Defensive Ink Secretion of the Sea Hare Aplysia californica
Three new mycosporine-like amino acids (MAAs), aplysiapalythines A, B, and C (1, 2, and 3, resp.) were isolated from opaline, a glandular component of the defensive ink secretion of sea haresExpand
