How lobsters eat jellyfish without harm from venomous stingers

Hiroshima University scientists examined lobster feces to discover that the crustaceans surround their servings of jellyfish in protective membranes that prevent the stingers from injecting their venom. The results inform aquaculture efforts to sustainably farm lobsters, the university said in a news statement.

Phylum Cnidaria (meaning nettle-like) is an interesting group of more than 9000 species. It takes its name from cells called cnidocytes, which contain the stinging organelles called nematocysts. Nematocysts are formed and used only by cnidarians. Another name for the phylum, Coelenterata (meaning hollow gut) is used less commonly than formerly, and it sometimes now refers to both radiate phyla (Cnidarians and Ctenophores), since it's meaning is equally applicable to both.

The phylum Cnidaria includes some of nature's strangest and loveliest creatures: branching, plantlike hydroids; flowerlike sea anemones; jellyfishes; and those architects of the ocean floor, horny corals and stony corals.
