To kill them:

Step 1: guide them to the shore

Step 2:destroy with a spear

Step 3:gather the biotoxin

Step 4:realize that you failed step 1 and they had killed you and your spino

Basilos are immune to their stun so you can easily take out groups and really show them who’s boss. Otherwise just use a crossbow at a bit of a distance.

P.s RIP dodo Kevin

Use a cross bow , it’s great against cnidaria.

If I see the Cnidarias, I’m getting my brontosaurus who I named Death tail whipping them out of here.

They definitely not found in the deep ocean I found them at the surface and lost my beloved Bloodstalker

To fight these guys get a basilasaurus they are not affected by them and they are the third best bio toxin collector.

Just don’t fight them without at least a pike :| (short story short I gawt clapped)

If you can chain stun-locked by 2-3 or 4 of these jellies, It's over, you literally can't move

Who in wildcard said “I have an idea” cause I was stoped after I caught my first dunky (: and I was trying to get her to my herbivore island base when we got attacked by an alpha Meg. We trying to fight against like 20 other sharks when a single, A SINGLE Cnidaria came from below and killed marrowhack :( 1 up = I feel that pain

My level 124 baryonyx could kill these with relative ease. If you want lots of bio toxin then invest in a baryonyx.

Us a basilisaurus and they won’t dismount you and you can collect all the Botoxin you want while jamming Free Bird and high as a kite…

Aggro all of them in the water and bring them close to land, then get on land and kill them off one by one because they won’t move. Spear or bow for efficiency

I was running around with a pack of 6 raptors and decide to beat the heck outta these guys for killing my first itchy so I run up to them and two seconds later 6 death messages appear on the respawn screen I respawn and just see 6 dead raptors rip spud gang

Encountering? Dont. It will save you your tames, time, and sanity

RUN, first thing I found died immediately

No, it doesn’t matter how strong your Dino is. These things can and will kill it. Avoid at all costs.

These guys aren’t to bad if you see them before they can see you, or if you have turtle or basilo

Always have a basilo. They don't get stunned by this

Warning:

Do not go in if you see these.

Just kill them from shore

The reason I can’t craft anymore arrows…
