The whales - particularly the blue whales - are the biggest saltwater animals.

Some saltwater habitats are naturally in cold areas so the animals have adapted to the cold by having thick coats, blubber, and paws that can walk on ice.
no
Not saltwater fish, but some freshwater animals/fish.
Saltwater animals have adaptations such as special glands to excrete excess salt, streamlined bodies for efficient swimming, and camouflage to avoid predators. Some animals have symbiotic relationships with other species to help them survive in the harsh saltwater environment. Ultimately, these adaptations help saltwater animals thrive in their ocean habitats.
Some species of crayfish, such as the spiny lobster, are saltwater animals, while other species, such as the kabby or koura, are freshwater animals. It all depends on which species of crayfish you are referring to.
Some animals that live primarily in saltwater need fresh water because saltwater does not absorb the necessary impurities from their metabolic systems. Salmon and some species of eels spend part of their life cycle in fresh water (where they have to retain salt) and part in the sea (where they have to balance their body salt with the saltwater around them).
it makes it hard for the animals to breath
Yes they are marine animals.
Only animals that can live in freshwater or saltwater live in an estuary because estuaries are places where freshwater and saltwater meet.
