Swordfish are elongated, round-bodied, and lose all teeth and scales by adulthood. These fish are found widely in tropical and temperate parts of the Atlantic, Pacific, and Indian Oceans, and can typically be found from near the surface to a depth of 550 m (1,800 ft), and exceptionally up to depths of 2,234 m.

Protosphyraena is a fossil genus of swordfish-like marine fish, that thrived worldwide during the Cretaceous period (Albian-Maastrichtian). Fossil remains of this taxon are mainly discovered in North America and Europe, and potential specimens are also known from Asia, Africa and Australia. [1]
Consequently, the predators and prey will be locked in an evolutionary arms race, each looking to gain the upper hand on the other. The presence of fish predators play a large role in the size, shape and swimming performance of the Lithobates clamitans tadpoles. The presence of these predators in their habitat causes the tadpoles to develop ...

Golden mussels, an invasive species that officials across the country have been worried about for years, invaded North America for the first time through the Port of Stockton.
The marlins are Istiophoriform fish, most closely related to the swordfish (which itself is the sole member of the family Xiphiidae). The carangiformes are believed to be the second-closest clade to marlins. Although previously thought to be closely related to Scombridae, genetic analysis only shows a slight relationship.
