Swordfish are ectothermic animals. Along with some species of sharks , they have special organs next to their eyes called heater cells which function to heat their eyes and brains. [ 13 ] Their eyes are heated to temperatures measured between 10 and 15 °C (18 and 27 °F) above the surrounding water temperature; this heating greatly improves ...
Using the weight calculation formula, the swordfish measured 138 inches overall — 98 from the lower jaw to the fork of the tail — and had a girth of 64 inches. "It was a fat fish, too.

There is only one order and family in this animal class. All of the 77 known species have elongated, eel-like bodies but can be distinguished by their downward-facing mouths. The largest form is the Goliath hagfish (Eptatretus goliath). This species can range up to 1.28 m (4.2 ft) in length and weigh to 6.2 kg (14 lb). [19]
Unlike axons of other animals, squid axons are very large. Those of bigfin reef squids can range in diameter from 350 to 560 μm (in contrast to the typical 1 μm for humans). [ 31 ] [ 55 ] In life, these giant axons are used by the squids to coordinate escape jetting behaviour, enabling the squid to contract its muscles in a split second ...
If this is a problem with dolphins it is an even greater problem with billfish such as swordfish, which swim and accelerate faster than dolphins. In 2009, Taiwanese researchers from the National Chung Hsing University introduced new concepts of "kidnapped airfoils and circulating horsepower" to explain the swimming capabilities of swordfish ...
The Chinese paddlefish (Psephurus gladius; simplified Chinese: 白鲟; traditional Chinese: 白鱘; pinyin: báixún: literal translation: "white sturgeon"), also known as the Chinese swordfish, is an extinct species of fish that was formerly native to the Yangtze and Yellow River basins in China.
