Toxic, antimicrobial and hemagglutinating activities of the purple fluid of the sea hare Aplysia dactylomela Rang, 1828.

An Examination of the Antibacterial Effect of the Ink of Persian Gulf’s Sea Hare Aplysia dactylomela on Some Aquatic Pathogens

,Different variations of Aplysia have been appealing options in medical and pharmaceutical researches for years. Persian Gulf’s sea hare—Aplysia dactylomela—is a species native to Persian Gulf and can be evaluated in various areas. In this research, carried out in 2019 in Persian Gulf University’s Research Centre, the antibacterial potential of the ink of this species has been measured against ...

Molecular Identification of the Persian Gulf Sea Hare (Aplysia sp.) Based on 16s rRNA Gene Sequence

Background: Sea hares of the Aplysia genus are among the mollusks of interest for various researchers to study their phylogeny, bioactive compounds and the nervous system. These mollusks are herbivorous and produce chemical compounds (ink) to defend themselves. The present study provided molecular identification of the Persian Gulf (Bushehr city) sea hare using 16s rRNA gene sequence. Materials...

Effects of CO2 driven ocean acidification on sea hare (Aplysia dactylomela) larval development

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

Sea hares protect themselves from predatory attacks with several modes of chemical defenses. One of these is inking, which is an active release of a protective fluid upon predatory attack. In many sea hares including Aplysia californica and A. dactylomela, this fluid is a mixture of two secretions from two separate glands, usually co-released: ink, a purple fluid from the ink gland; and opaline...

Intraspecific Variation in the Purple Secretion of the California Sea Hare, Aplysia californica Cooper

THE SEA HARE is probably best known because of the red to purple fluid secreted from the margin of its mantle. There is only a superficial resemblance between this secretion and that of the genus Mttrex, which is the source of the anciently famous dye, "Tyrian" or "Royal Purple." Aplysia purple, however, found no practical use, probably because of one important deficiency-it turns a dirty brown...
