Do other animals in this environment have similar adaptations? Which animals?

Question

Ok my 9 yr old son has to do a Report and he pick to do a report on swordfish well we have the rest of the report. But this is the last question we can't understand or find a anwer to ... help me

Answer 1

Okay, if this is for a 9-year-old, the teacher must be looking for something more simple than the answer given above.
Swordfish have a sword, which is an adaptation that helps them get their food. Marlins also have this adaptation as do narwals and other marine animals.

Answer 2

Swordfish have the widest temperature range of any billfish and migrate seasonally to warmer waters in winter and cooler waters in summer. This highly migratory species can often be found where ocean currents meet and productivity is high. Although the Swordfish is typically found in shallow waters, they are thought to swim as deep as 650 m. They are uniquely adapted to cold, deep waters by the presence of specialized tissue near the eyes that heats the brain through the tissue's blood supply, which is a vascular system similar to that used to heat and cool the bodies of other large pelagic fish species such as tuna. These adaptations help the fish move quickly through rapid temperature changes in the water column.

Answer 3

There are many many different answers for this because it's a VERY broad question. You may be referring to amphibian (living on land and in water, not literally amphibians) animals such as Emperor Penguins, which go inland to mate around fall and then return to the sea to feed around spring (a lot longer process than that, that's just a summary) or perhaps referring to subarctic animals like arctic foxes, which shed their coats and create brown ones when the snow melts, but form white coats when winter comes around. If this is indeed for a project, I shouldn't need to give you all the details, just get you going on the right track, so I'll leave you with those ideas.
