New Polyhalogenated Monoterpenes from the Sea Hare Aplysia punctata
Journal of Natural Products, 1997The sea hare Aplysia punctata from Sancti Petri (Cádiz, Spain) contains four new unusual acetates of linear polyhalogenated monoterpenes (5-8) together with four known cyclic derivatives (1-4). The structures were elucidated by interpretation of spectral data. It is suggested that the new constituents of A. punctata might be biotransformation products.

Occurrence of phosphonotetraglycosyl ceramide in the sea hare Dolabella auricularia
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1993Two kinds of phosphonoglycolipids were isolated from the sea hare Dolabella auricularia. One was phosphonopentaglycosyl ceramide with the same structure as that of the phosphonoglycolipid obtained from the sea hare Aplysia kurodai. The other, phosphonotetraglycosyl ceramide, was discovered in this study.

Dietary metal toxicity to the marine sea hare, Aplysia californica
Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2015Metal pollution from anthropogenic inputs is a concern in many marine environments. Metals accumulate in tissue and in excess cause toxicity in marine organisms. This study investigated the accumulation and effects of dietary metals in a macroinvertebrate.

Bradudol and isobrasudol: two bromosesquiterpenes from a sea hare ( )
Tetrahedron Letters, 1979Abstract The structure and stereochemistry of two closely related new feeding deterrents, isolated from the digestive glands of the mollust Aplysia brasiliana , are reported. These compounds, which proved to be brominated eudesmanes, have the same absolute configuration as natural β-eudesmol.

A new apocarotenoid from the sea hare Aplysia kurodai
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1990Abstract 1. 1. The carotenoids in the viscera, muscle and gonad of the sea hare Aplysia kurodai were investigated. 2. 2. A new apocarotenoid α-citraurinol [3 R , 6 R )-8′-apo- ϵ -carotene-3,8′-diol]( 1 ) has been isolated from the sea hare.

Lifetime energy budget in the sea hare Aplysia oculifera
Comparative Biochemistry and Physiology Part A: Physiology, 1996We studied energy budget and resource allocation through the entire postmetamorphic life span, under controlled laboratory conditions, in the sea hare Aplysia oculifera from the Red Sea. Growth of sea hares was according to the Gompertz equation: Body live mass (BLM)t = 105 exp[− exp{−0.053(t − 43.04)}.

Human poisoning by ingestion of a sea hare (Dolabella auricularia)
Toxicon, 1988A case-report of poisoning by ingestion of a sea hare, which is thought to be the first report of human poisoning, is presented. The clinical signs were mainly neurological with tremor, psychomotor over-activity, ataxia and muscle twitching being predominant. It is suggested that organic bromine compounds are responsible for the effects.

Bacteriostatic and cytolytic activity of purple fluid from the sea hare
Developmental & Comparative Immunology, 1990A bacteriostatic factor, aplysianin P, was purified from the purple fluid of a sea hare, Aplysia kurodai, as a glycoprotein of 60 K daltons. A cytolytic glycoprotein purified from the purple fluid of Dolabella auricularia did not show antibacterial activity.

Antitumor Effects of Sea Hare-Derived Compounds in Cancer
2014Sea hares (family Aplysiidae) are a rich source of bioactive substances. Especially, over the past 40 years, the genera Aplysia and Dolabella have afforded numerous bioactive secondary metabolites that exhibit antitumor activity. For example, the depsipeptide dolastatin 10 and its analogue are currently in cancer clinical trials.
