No, it applies to land animals. Sea animals fall under a different set of rules, as do animals which fly. In the water you may eat true fish, ie, things that have fins and scales. This means no shellfish, no lobster, no crab, etc. As far as birds, you can't eat birds of pray or carrion eaters.
You can't eat insects, EXCEPT for locusts, which are indeed kosher for eating (not that i personally ever met someone who wanted to eat one), and you can't eat things that creep, like worms, and things of that nature.
As far as land animals, if it exists on land, it has to chew the cud, and it has to have cloven hoofs. otherwise it can't be eaten. If an animal is not kosher, then no product derived from it is kosher with one exception. Bees are NOT kosher to eat, but their honey is.
