The dossier flat out lies, these things will agro from a fairly long range and pursue you quite insistently they also spawn in the shallows A LOT so if you planned to build a comfy open dock from which you could appreciate the sunset, well tough luck get used to your drab behemoth gates.

Sometimes they are REALLY close to the shore and if you are low lvl you can kill them with spears and harvest the toxin for taming.

I’m not sure if this is just a glitch or not but my otter will kill them and harvest them and they won’t attack my otter.

If you want to kill one of these guys just go near them draw them shore and spear them with this tactic I took out six at once

Three of these killed my sarco. It was shallow water, and my sarco had over 1k health. I’m sorry, Snapple =,(

These glowey demons should be removed

This is a war between players and jelly fish

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

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

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

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

These are just better narcotics in mobile

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

You get bio toxin from these guys

These are ez kills just get a crossbow back up and keep shooting them I fought 5 of these and a lvl 49 megalodon was easy I just swam up and backed up but I did have scuba

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

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

0 narcotics?? Don't worry about narcotic. Find this guy in the sea kill this guy and bring its meat and Feed any creature u want to tame. It change narcotic to super narcotic

Fre narcotic

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.
