Bold Seagull
strong and stable with me, or...
The salt water croc doesn't just laze around in brackish rivers. It swims out into the ocean to kill and eat SHARKS.
It eats small sharks that swim a bit too close to shore, or get disorientated in river estuaries. The idea that these crocs are swimming out and attacking big sharks is fanciful, it's just a smallish fish to a SWC. Nothing hard in eating fish for dinner...
