Technically all animals can become sick.
However, some animals have such remarkable immune systems that they almost never become sick and are sometimes discussed as an animal that "cannot" become sick.
Labeling an animal as one that cannot become sick is really overzealous as they are just highly unlikely to become sick and not actually 100% immune to everything, just most things (and possibly everything) in their natural habitat.
If they were however exposed to something from outside their normal environment, it would be possible for them to be sick.
Animals often referred to as not being able to get sick are:
The Hippo
The American alligator
Komodo Dragons
These are animals which spend a lot of time in and around filthy water and often ingest decaying or rotten food. The build up to their immune system makes them virtually invulnerable to anything in their native area, but they can still get sick if taken out of that habitat and exposed to new germs

hippoANS 2 -I really don't believe there is an animal that never gets sick.

There is no sea animal that never gets sick. All animals are susceptible to illness and disease, just like humans. However, some animals may have stronger immune systems or better defense mechanisms that make them less likely to get sick.
