Sea Hares from the Red Sea

May 25, 2000
From: Alaa youssry Moustafa

Dear Dr.Bill
Let me inform you that, I have been working on sea hares for 5 years now. I have got my M.Sc.on the biology and the chemical defence of sea hares collected from the Red Sea, EGYPT (Aplysia dactylomela, A. cornigera [PHOTO B]], A. oculifera [PHOTO A], Dolabrifera dolabrifera [PHOTO: E] and Petalifera petalifera). I hope to continue in the same line in the study of the Doctoral degree.I need your advice and your suggestions.

My study includes:
1- Making a survey of sea hares collected from the Red sea, we identified six species, studied their taxonomic characters, presence, feeding habitat.
2- Detailed study of the anatomy, histology, histochemistry of the reproductive, digestive, nervous systems of Aplysia dactylomela, Dolabrifera dolabrifera also, with TEM and the SEM.
3- determined the LD50 of a crude extract of the digestive gland of the previous species and show its pharmacological characters.
4- isolation of two different algae from the filter chamber (Gyminodinum)[PHOTO: D] from D. dolabrifera and the green algae Oedogonium [PHOTO: C] from A. dactylomela.

Also, we derived some aliphatic terpenes from their digestve glands. I hope to study in my PHD the chemical defence.

Dear Alaa,
I am glad to hear of your interest in Sea Hares. Any questions, observation, photos etc are welcome.

I am also sure that now other workers know of your interest they will contact you directly.

Look forward to hearing from you,
