I have recently discovered that these are by far the most valuable tame for any level of player.
Why you ask? Try taming 1 and then put anything at in it's inventory and see what happens ;) also you don't have to feed them AT ALL

Don’t kill them yet wait until you are up at late-midgame levels before you start trilobite hunting

These are tameable for Pc Users, all you need to learn is the Fish Basket engram and drop one down near a high lvl trilobite and then stand in the trilo’s way and guide it til it’s near your basket then capture it, release it before it expires in your inventory then cryopod it up for save keepings! Trick no ones sharing is you can hide blueprints in abberation trilobites and then hide them underwater ;) p.s you can also tame leeches and then leave them on aggro for biowarfare at obelisks or transmitters lol or Sabre salmon then catch release then cryo them for easier otter taming or attaching c4 to said salmon then attacking underwater targets....

Hey guys for those who are playing on the island at the bit u spawn on the trilobites spawn mostly at 12:00 hope this helps someone

Kill just one of these and harvest with a chainsaw for 300, 400 chitin plus oil and pearls

These are soooooooo valuable, you may not need them right away when first playing the game, but kill them and collect everything they drop anyways. Kill them when you dont need them, because eventually, you will, and if you dont, you'll regret it later. I go whole days trilobite hunting on my spino.

I once got 157 chitin from just one of these!! Definitely recommend going for these guys for chitin and oil, pearls (you get both) are just a bonus! They like to spawn around beachs and shallow rivers #Wolfs4Life ❤️❤️🐺❤️❤️ -Wolfa191

I have some requests please make them tameable on mobile and island. And when tamed can they please produce black pearls? PRETTY PLEASE

Kill them, they’ll give you late game Resources like Silica Perl’s black Perl’s and oil.

I struggle to find silica pearls on the island so at one point in time I hunted these guys down to the brink of extinction. (I basically just slaughter them).
