RE: Are slugs edible?

Dear Bill,
Concerning sea slugs being edible. It seems that sea slug such as Aplysia kurodai have eaten for many years in some parts of Japan such as Tottori Prefecture, Japan Sea and Fukushina Prefecture, on the Pacific coast but not as a staple food. I tried to find more detail and seems they boil and seasonit. It tastes like octopus. I think A. kurodai usually eats non-poisonous green algae so it is safe as food. Nudibranchs which eat sponges, ascidians and hydroids may be dangerous for food.

Best Regards,
Nishina Masayoshi

Thanks Nishina,
It would be interesting to know if they eat all the Sea Hare or just the body wall. Do they clean out all the digestive gland and gut etc before it is prepared for eating?
Best wishes,
Bill Rudman
