Besides this means of defence, an acrid secretion, which is spread over its body, causes a sharp, stinging sensation, similar to that produced by the Physalia
, or Portuguese man-of-war.
Bluebottles, whose scientific name is Physalia
utriculus, resemble jellyfish but are only a relative of those creatures.
A caution could have been included regarding handling aeolids, particularly Glaucus species likely to be found washed ashore, as the concentrated nematocysts can give people a sting more painful than man-of-war Physalia
species (Rudman 1998).
The Northeast Canyons and Seamounts Marine National Monument includes two areas: one that includes four undersea mountains - Bear, Mytilus, Physalia
, and Retriever; and an area that includes three undersea canyons Oceanographer, Lydonia, and Gilbert that cut deep into the continental shelf.
Intracellular recordings from single cnidocytes in the tentacles of Physalia
(Purcell and Anderson, 1995) and Cladonema (Price and Anderson, 2006) revealed bursts of synaptically-driven electrical activity in cnidocytes after perfusion of the tentacle with prey-specific chemical extracts.
In spite of several co-occurring species, including Olindias sambaquiensis, Physalia
physalis, Stomolophus meleagris, Lychnorhiza lucerna, Chiropsalmus quadrumanus, the jellyfish Chrysaora lactea was the only clear cause of the stings during the summer of 2011-2012 in Parana.
La pesca pelagica en esos mares esta siempre llena de micro organismos: amphipoda, leucifer, copepodos, salpas, sagitte, hidromedusas, doliolum, radiolarie, zoea y halobales; tambien recogieron muchos planaria, pequenos physalia
, algunos glaucus y cefalopodos.

Ademas de este medio de defensa, el cuerpo esta untado con una especie de secrecion acida, que en contacto con la piel produce una sensacion de quemadura parecida a la ocasionada por la physalia

Charles Richet, a good friend and fellow physiologist of William James, was invited in 1901 on a cruise aboard the Yacht of Prince Albert of Monaco: "The Prince advised me to study Physalia
