Series 1=Edit

Super-sensitive electric sensors enable them to track their prey better then any submarine and they have the weapons to finnish it off, the Lemon shark.

Pole to Pole=Edit

SUPERB SENSES: With a sweet set of super senses to find prey,
DEADLY GNASHERS: their rows of thin pointy teeth snag into fish,
MASSIVE BITE: and their bite can swallow a beach ball,

Lemon sharks are a formidable fish munching machine with jaws for the job.
