Tier One
Very good starter for the reef, just about nowhere else though, because there are no easy hiding places anywhere in the open ocean, and a stray otter or hammerhead shark will eat you just because you were in their way in there. If there are other Clownfish nearby, stick with them for the speed boost, but be wary if they evolve to crab and try to kill you. Also just farm on floor food next to a anemone until you can evolve to crab, then go on an island and find yourself a coconut crab. They will most times be a good protection while you eat berries.
Worst stats of any tier one, but lives probably in the easiest location to level up in, the deeeep. There are volcanoes to hide in everywhere, and they generate the second highest xp granting food. (the highest being meat) You probably have the highest chance of survival as Blobfish, just because the deeeep is so spread out.
Good for the same volcano reason as Blobfish, but as an advantage you heal faster standing still, so when you are in a volcano nearly dying, you will recover faster.
Literally completely useless. Why would you even choose it. It is blind. That's its only ability. Move on to the next animal.
The best swamp tier one, but has some occasional issues with the boost bar displaying properly. Its boost is very helpful, because it is one controlled dash, not just a single burst like most animals. You can also choose to get more Piranhas as you level up. Beware though, if you don't choose Piranha every time, the evolution path is lost.
Similar to Bobbit Worm, as it can easily dig, but floor food doesn't collect to you as well from inside the ground, so you must go outside to farm well. Also, never turn into lamprey in the ground as it will just get you stuck in the dirt. Wait for you to emerge to the surface to do that.
Tier Two
Is best at farming berries, as it sinks in water and can not swim well. Just hop onto an island and eat as many purple berries as you want. Don't be scared of Coconut Crabs; they can't hurt you. But seagulls can seriously mess up your day, but there is an easy fix to that. If you stand still in a bush, you will be invulnerable and be invisible.
Just like crab, but you live in the arctic and have a very rare stat: damage reflection. This repels the percentage of damage given to you (as indicated on your stats list) back to your attacker. This means you can hunt jellyfish, but you have to facetank them, if you let them get away, they will heal, while you take damage.
Unlike its previous evolution, this cavefish can see, and if you charge your boost, you will dash out of the water, and if you hit a ceiling, you will stick to it and be able to walk. This is very helpful for escaping predators.
Probably the most useful ability out of all the tier twos, if you boost into the ground you start digging really fast. You can even cross through from the lower swamp caves to the upper part, completely bamboozling your pursuer.
Stick to animals that you know don't breathe air, because you will suffocate out of water. Examples of optimal choices include: Gar, Sunfish, Moray, Whale shark, Shark, Sleeper Shark, Goblin Shark, Colossal Squid, and Giant Squid.
Tier Three
The first hit and run animal you will find on this list, its whole point is to hit a low tier, and wait for them to succumb to poison. Best to stick next to an anemone, because you are actually quite fragile. If you want to troll a whale, purposely get yourself sucked inside them, they will keep taking poison damage until they breathe, so you could kill some like that.
You can bob out of the surface to fly away from your problems. you can gain speed by boosting upwards, then swooping down. You are also already naturally fast, and can run from most animals.
Probably the best tier three for one reason; there is a glitch where if you have any boosts, and you hold down boost, you keep going with +50% speed until something slows you down. I have tried to test the limits of this, and it appears there isn't if you start with a full boost bar. You can kill squids and other tier threes just by repeatedly slamming into them at high speeds. As for peaceful ways of getting xp, you can look at the Crab entry, but watch out for coconut crabs, as they can hurt you now.
Also blind like the Blind Cavefish, but has a boost similar to Horseshoe Crab, and regens boosts when standing still. Your best bet would to find a empty log to hide in, regen boosts, speed across the floor for xp, and repeat that until you reach tho other end of the swamp.
You jump high. That's about the only ability you have. I don't know, just eat dragonflies until you can evolve.
Tier Four
Probably the most used tier four, and a helpful ability; you can disappear by standing still. Not just invisible, but invincible too. The only drawback is that you can't do it after being hurt for three seconds. Certain places (like the pineapple) can automatically let you enter the invisible state. Make sure you avoid animals with suction attacks, like Frogfish and Whale, because they can disable your ability, even if you are using it.
First tier that can truly "fly" (flying fish is gliding), but has not amazing stats. The advantage is you swim normally, as opposed to Pelican, Bald Eagle, Seagull, Bat, and Duck.
Probably the best tier four, because it has armor, so you can easily hunt Barreleyes in the deeeep. You can also use a boost to be completely invincible, but you sink, and can be affected by bleeding, and Colossal Squids' slaps. You are best just sweeping the floor from left to right until you can evolve. Amd, while sweeping the floor, you get a 30% speed buff
Similar strategy to Icefish, but you don't live near volcanoes, and cant hide in logs. Essentially just hunt tier threes and heal after battles. You can walk to escape predators though.
Very good tier four for swamp, as you can use a suction attack for free by charging for 2 seconds to suck in food and prey. you can increase the xp gain by spinning in a circle to get all the plankton around you in a circle.
Tier Five
Not a very good tier, because it is murdered by Bald Eagles. Most people skip this tier, and if you want to know how, you just need a minimum of 55k xp to evolve past it. If you really want to play it though, farm off berries and apples, you can hide by standing still in trees, and Pelicans can't hurt you. If you go hunting in water, make sure to keep predators below you, and prey above, because you are buoyant and go fast upwards, but slow downwards in water.
You are already very fast, but if you go to the ground, you get even faster, and you can eat floor food as an added bonus. You can hide in icebergs, and turn invisible (but not invulnerable) while standing on land in the arctic or ocean-arctic. Your speed makes you very good at hunting, and running away. your best bet would be to hunt squids, starting with a boost to disable their invisibility, then finishing them off with speed.
You can see animals before they can see you, but only as a radar effect in a ring around you. the animals get darker as they get closer, and when they disappear, they are either in your screen, or away from your radar range. You almost never get killed because you know who's coming before they see you. But, even thought they are lower tier than you, you can not facetank an Isopod. Their armor halves your damage, but you have no special stats, so they end up killing you. If you really want to kill them, hit each other, run away and get some xp to heal, hit them again, and repeat. if they keep following you, you should be able to beat them. If they leave, so what? They cant kill you now.
Amazing for killing walking animals. This is because you walk naturally on the ceiling,so when you are near the floor,you can get pretty close before you actually start walking. Now if you see a snapping turtle or something walking in an island, get right next to the floor and push into them the opposite direction they are walking, and use your charge boost to slow them down if they run. They will take rapid damage, roughly amounting to 200 dps, and usually be killed. Just watch higher damage animals like Hippo, as they can slap you to death if you attack for too long. Because you don't have temperature damage, you can go to the arctic, because a lot of animals there walk and you can kill them. And there is only one animal in the arctic with armor, the lobster, but they don't come out of the water much, so they cant really hurt you. Just watch for Orcas, as they will throw you into the water and try to drown you or waste your salinity.
You are essentially a seagull with better stats, and can hide in beaver dams. Not much to be said about the Duck, just watch for Crocodiles trying to grab you.
Tier Six
Easily one of the best tier sixes, it can grab, inflict bleed, has armor and armor piercing, and can walk with decent oxygen time. Just hunt seals and squids, just absolutely end them, they can't do a thing if you pin them. If a big animal like Orca or Whale comes, you can charge boost into them to cling to them and deal dps. Also, if you are out of boosts, you can hop on an iceberg and walk around until they leave.
You can scoop up small, tier four and below animals into your beak, where they will stay there for a while or you click again. This is good for catching animals until you can put them in an abovewater pool, where you can then pick them off. You can't eat berries anymore, but you can eat coconuts.
Like squid, it turns invisible and invincible, but instead of standing still, it has to put its head to the floor. You can easily get on the leaderboard by floor food farming until a predator comes, then you put your head on the floor and hide until they leave. Not very good at hunting though as it has no special stats.
By yourself, not a very good animal, but you are immune to poison, but when you boost, you dash a small distance, but you puff up, and you get: 50% armor, 70% damage reflection, and badly poison anyone who touches you. When you are puffed up, you can kill many tier tens if they facetank you.
Arguably the best tier six, It can dig, digs fast, can eat floor food underground like it was in water, and can grab tier 6 and below with its boost. A super helful tip I discovered to maximize hunting gain is to, when they are at half HP, quickly let go, and grab them again and finish them off. Just beware of Orcas and whales, as they will grab/suck you out of the ground and take pressure damage and you will most likely die.
Even though at first glance its ability seems pointless, if you hit a flying animal with the drop, they will get stun and sink for 2 seconds, and you will get +40% speed for those 2 seconds. If you manage to hit a Duck over water, it's as good as dead if you are a good player.
It is like Frog, It jumps high, but if you charge boost and swallow an animal tier 4 and below you can spit it out as a projectile, and whoever gets hit by it takes damage, and the animal you just spat out gets stunned when it his something. Best to hunt animals like axolotls and catfish, where you can swallow them, then shoot them at a surface to pin and kill them.
