Ok, it's been a while since I didn't make one of these, but after my Pacific ocean and Mediterranean sea threads, I think this was the natural progression.
For the record, this isn't necessarily about fully aquatic animals. Birds, pinnipeds, or even island animals that never venture into water can be accepted as well.
Rules
You must pick up to 4 OR 7 habitat animals, depending on whether you want a Scenery pack or Animal pack.
You can pick only 1 exhibit animal (but you can chose to not have one).
No extinct animals, but animals extincts in the wild are okay. No fantasy animals or unverified cryptids.
You can vote for one animal to be the dlc's mascot (the one put at the forefront of its banner) by writing "Mascot" between brackets. You can also vote for a scenery theme.
All animals must be native from the Atlantic ocean. The rules for what is considered part of the Atlantic ocean are as follow:
All seas, gulfs, straits and other bodies of salt water contiguous to the Atlantic except other oceans or the Mediterranean sea are considered part of the Pacific ocean. It continues until you reach land or another ocean. So the Baltic and Caribean seas, gulf of Mexico, etc. are all taken into account.
Islands entirely surrounded by the Atlantic ocean are considered part of the Atlantic ocean.
The coasts of continental land masses touching the Atlantic ocean are considered part of the Atlatnic ocean, to a reasonable extent (don't use it as an excuse to include an animal who only lives to the West of the Appalachians, for instance).
