Thestingrays are a family---Dasyatidae---of rays, cartilaginous fishes related to sharks. They are common in coastal tropical marine waters throughout the world, and several species are known to enter fresh water. Other types of rays also referred to as "stingrays" are the river stingrays (family Potamotrygonidae), the round stingrays (families Urolophidae and Urotrygonidae), the sixgill stingray (family Hexatrygonidae), and the deepwater stingray (family Plesiobatidae). For clarity, the members of the family Dasyatidae are sometimes called "whip-tail stingrays". While most dasyatids are relatively widespread and not currently threatened, there are several species (for example Taeniura meyeni, Dasyatis colarensis, D. garouaensis, and D. laosensis) where the conservation status is more problematic, leading to them being listed as vulnerable or endangered by IUCN. The status of several other species are poorly known, leading to them being listed as Data Deficient. To get it to the point, stingrays are Ectothermic.Okay?

"Around level 60, fishing for them at 50 can be slow and unrewarding." Personally I think at level 65. At this level, you're allowed to use Fist of Guthix swordfish gloves, and they give you an additional 100 xp per swordfish. Only with these gloves does fishing for swordies outweigh lobster caging, because of the frequency of tuna.

yes

Size and Lifespan: Adult swordfish can grow to 177 inches in length and weigh up to 1,400 pounds. Females tend to be larger then males. Pacific swordfish are the largest of their kind. West Atlantic swordfish are no more then 700 pounds. Mediterranean swordfish weigh up to 500 pounds. Swordfish lifespan reaches 9 years, and they reach sexual maturity at around 5 years.

A swordfish protects itself against predators by using it's pointy sword like nose to slice the predator into pieces!

The life cycle of a fish starts with an egg, which generally hatches to produce a larva that gets nutrition from a yolk sac on its body. When the yolk sac is depleted, the larva becomes a fry and starts finding its own food. The fry later grows into a juvenile, and then into an adult. However, not all fish go through all the stages.

No. swordfish are not 'schooling' fish. They hunt alone and feed on other fish.
