Sharks!

The more sharks they add to game the better it will be.

Period.

End of story. 

Sharks in the seas, sharks in the rivers (oh yeah, they go there, look up Bull Sharks (Carcharhinus leucas)), sharks you can fish up in fishing nodes that will then eat you (see: "Deep Blue Sea"), sharks in the fountains, sharks in the trees, sharks among the flowers, sharks as mounts that are rocket propelled (or some kind of nuclear energy source, I'm not picky), sharks that will give you directions in the cites (or better yet, you have to rely on the RNG as to whether they give you directions or they eat you.)  
                                                
                                            More sharks, please!

Gentle Giant my butt, this guy'll kick your ass.

Shrouded Cetacean - umm... I'm guessing it's a play on words here. These are Whale Sharks, Whales are also the name for aquatic mammals, who are in a family group called Cetaceans.

Whale Shark
Rhincodon typus

The largest fish in the sea and one of the most gentle; Whale Sharks eat krill and other plankton by filtering it from the water.
 
Woot Tech Moment (WTM): They are starting to use the computer algorithms normally used to identify constellations and star patters to identify individual Whale Sharks.

Great White Shark
Carcharodon carcharias

The best of the shark species - more of these in game please!  They'd make a great final boss.

Bluetip Thresher

Thresher Shark (Alopias vulpinus)

Sharks have some great variation, and this one has a tail that can equal up to half the entire body length.  They are active hunters sometimes using the tail to stun prey.

Spinescale Hammerhead

Hammerhead Shark

Great Hammerhead Shark (Sphyrna mokarran) and can reach 20ft and 1,000lbs.  They often feed on stingrays. They sometimes mass in great numbers, presumably to breed, but it has never been recorded.

Great Reef Shark

Reef shark

Blacktip Reef Shark (Carcharhinus melanopterus). These guys live closer to shore, around reefs (go figure) and are quick, agile hunters.

The ones in game are more Mako shark shaped. (see below).

Mako Shark

A sad picture of a Mako Shark, but the best match for the ones I've seen strung up in-game. 
These are lesser cousins of the Great White shark. They live and hunt in open waters, often going after sailfish and swordfish.  They are one of the fastest sharks, swimming up to 40mph. They are also a favorite of sport fishermen.
