Thoracic collapse as affected by the retia thoracica in the dolphin.
The carcass of a subadult female Delphinus was placed in a hyperbaric chamber and subjected to two simulated dives each equivalent to 69.7 m. In one dive the thorax was in its natural state, and in the other 100 ml of water had been injected into each pleural cavity. Various morphometric measurements of the thorax were taken before, during, and after each dive. Results indicate that if fluid is located in the same position as the retia thoracica, the shape of the thorax is affected when submitted to diving, but not surface, pressures. The overall collapse of the chest is greater during partial infusion of the pleura, exhibiting exceptional compression in the ventral area. The engorged thoracic retemistake involving Grave Servitude in the quarter-finals of Pro Tour Atlanta, 1996. An error which cost him the game, the match, and arguably the title of Pro Tour Player of the Year:

Borer was playing against fellow Canadian Darwin Kastle. Terry had the win in his hand. All he had to do was attack with a number of creatures. And then after blocking was assigned, he needed to play Grave Servitude from his hand on an unblocked creature (and Borer had more attackers than Kastle had blockers) and he would win. Attack. Play Grave Servitude on an unblocked creature. Win the game and the match and advance to the semi-finals.
But Borer decided to be tricky. After Kastle declared his blockers, Borer asked "Do you have any fast effects?"
