The air sac is three or fourinches long. The social community of cells that build this structurecalled Portuguese man-of-war, show wonderful skill, asthey are able to sink or swim at will. The Albatross Ex-pedition describes them as follows: The slime on thesea weed for instance may have come from a most poison-ous jellyfish known as the Portuguese man-of-war, that THE LIVING STRUCTURES 115 .^77^, pn.

On fair daysthese formidable creatures lift their pink and blue oval 116 CELL INTELLIGENCE THE CAUSE OF EVOLUTION crests above the surface, but in rough weather they sinkand one of their streamers entangled in a tow net mightdo serious harm, as happens on the slime banks of Behr-ing Sea, where the cod fishermen suffer grievously whentheir lines come up smeared with a poisonous jelly fishexcretion. It was the Albatross that traced the cause ofthis Behring Sea fishing trouble to a jelly fish. We see that this colony of cells can sink when necessaryto evade the crushing force of the waves and again floatwhen the weather and conditions are favorable. This ani-mal looks like the ordinary sea weed floating on
