Why do all swordfish have ‘swords’? Use the word ‘inherited’ in your answer.

Answers

All swordfish have 'swords' because it is a characteristic inherited trait  from their parents.

Inherited traits are passed down from one generation to the next generation through genes. In the case of swordfish, the sword-like bill which is present  is a unique adaptation  that has been passed down through generations. This bill is believed to have evolved to help the swordfish in catching prey, defending themselves, and  also in attracting mates.

The swordfish that had longer bills were more successful in survival and reproduction, which is  the reason why this trait has been preserved and is   observed in all swordfish today.The traits that  are transmitted by the parent to its offspring during the process of fertilization are inherited traits. This inheritance is determined by certain rules of heredity.

Thus, all swordfish have sword as they are inherited traits.

The swordfish bill, on the other hand, is smooth and horizontally flattened, better suited perhaps for whacking larger prey like squid. Beyond their "swords," all billfish come equipped with a remarkable internal heating system for their eyes, keeping them ten to fifteen degrees Celsius warmer than ambient water temperatures.
