Otters likes shalow lakes and watterfalls. Best way to tame otter is to kill all salmons around it, cause corpses has long time before it disappears and straight away feed them without any intervals cause they dont have cooldown on feeding time. After tame pick it up and you will get insulation from cold. Leveling otter is best to give all stats to oxygen as it increase insulation resistance. And you will forget biome struggle :) good luck finding them.

They may be adorable, but if you hurt them or their fuzz buddies, they will become angery, and can actually do pretty decent damage. I'm a level 100 player with around 250 HP and when unarmored, 7 can kill me in seconds. They also can do a number on your armor. Otherwise, they are cute and cuddly and friendly.

On Aberration having trouble taming otters? Use a crab pick it up dip claw in water now otter is high enough to tame. No more dead fish blocking feeding prompt. Still tricky but faster by far. Tilting crab on rock or slight grade on side of river helps to dip claw, deeper pools also.

I’m no expert but I think I’ve found the best way to tame these guys. All you need is an Argentavis and 5-8x primitive spears. Our plan is to snatch the otter from the surface of the water with the Argy’s mouth grab (click right stick or C on pc). This part might seem a lil daunting but I believe in you. Once you’ve scooped up the otter keep it in the mouth of the Argy and find a nice body of water with plenty of sabertooth salmon. Land on the shore close to the water (the otter will stay in the argys mouth). Now use the primitive spears to kill sabertooth salmon (or any large fish). When killing a fish with primitive spears it will automatically start dragging the body. Now here comes the best part. With the otter in the Argys mouth which will be raised above you, it is actually possible and super simple to feed the fish to our otter friend. You now have an Otter with none of the headache.

I have 6! 4 of them are common colors, 1 is green and magenta, and the other is pink and purple!

Okay, so the way I tamed them is simply by first: kill any dinosaurs near it or in range of otter, next eat a rare flower, then it will come up to you and nibble on your argy (preferred mount cuz it can pick up the otter in beak), then use a ithyornis (or a weapon to kill the sabertooth salmon if you don’t have a ithy yet), then drag the magical (or less magical) fish over to the otter and feed it!

Worked 10/10 for me (it can get a bit annoying when the fish keeps getting in your face)
