Ark Nova: Waterwereld

Most sea animals must be accommodated in the two new special enclosures (small or large aquarium) and cannot be placed in other enclosures; only a few sea animals that also belong to another category may be placed in a standard enclosure or the reptile house as explicitly shown on the card (page 3–4).

Both aquariums must be built next to at least one water space (their water icon counts as water) and some animals additionally require adjacency to rock — if you place tokens in both aquariums to accommodate an animal, each aquarium used must meet any stated terrain requirements; splitting the required player tokens between small and large aquarium is allowed (see the example on page 5) (pages 3–5).

The wave icon has no effect when you play the card; instead, whenever you replenish the display and you add a card with a wave icon, discard the bottom card of the display and continue replenishing (discard one bottom card per wave icon revealed); ignore wave icons during setup (pages 4–5).

Yes — when you play a Reef Dweller you trigger the Reef Dweller effects of all Reef Dwellers in your zoo, including the one you just played, and you may choose the order to resolve those effects (page 4; see the example on page 5).

At personal setup each player draws 3 new Action cards, passes and keeps cards in a 3‑player pass draft so that you end up choosing 2 cards to use and discarding 1; you must finish with two different action types — if you somehow end with three of the same type you draw a random different type to use instead (pages 2 and 8).

You may take a new university only if the generic university tile is still on the Association board and you don’t already have one; taking it places the chosen animal icon on your zoo, lets you reveal cards from the deck until you find a card matching that icon and add it to your hand, and grants a research icon, and the generic tile is removed from the board until the next break so only one player can take a new university per break (page 6; setup references on page 2).
