Studies have proven that the bigger, female swords can tolerate colder surface waters much better than the smaller females and males. Of course, this refers to surface waters primarily, because the water that these big fish hunt in is literally frigid wherever they are swimming. Swordfish and sperm whales are the swordfish's only natural enemies. The one below was attacked after it died on the 'poon line. Crappy picture, but I thought some might like to get a look at it. As you know, makos have small mouths for their size and the one that did the biting here was a BIG momma!
