I found one of these and sudenly there were a lot of them around me... They just melted my Megalodon in a second and there was nothing I could do because of the electric shocks!

I advise you, If you arent well geared up and with a Basilo (which is immune to the shocks) please just try to leave this beasts alone, DONT TRY TO FIGHT THEM UNLESS YOU KNOW WHAT YOU ARE DOING!
