From: Hunting the Beasts of the Zee

They are regrettably large, distressingly ferocious and possessed of an alarming turn of speed. It was long theorised their ferocity could be attributed to protecting their spawning grounds. […] recent observations suggest a simpler motivation […] malice.

Game Instructions: As more Angler Crabs are hunted, they will become more elusive and rare – harder to hunt, and more rewarding.

Unlocked with Estimated Angler Crab Population is present (World Quality, now locked), Base Monstrous Anatomy 1

The Angler Crabs […] are a recurrent menace […] More crabs are produced […] than their ecologies can sustain; the excess roam the Unterzee […]

There is no one […] who doesn't know someone who hasn't come to a swift and messy end at the claws of these […] decapods. […]

• You have moved to a new area: Poring over the Maps
•  You are zailing towards the spawning grounds of the Angler Crabs. (Sets Zailing to Destination: to Angler Crab Spawning Grounds)
•  An occurrence! Your 'In Pursuit of a Zee-Beast' Quality is now 1!
•  You now have (a term scaling logistically with Estimated Angler Crab Population, see below) x Elusiveness of your Quarry
•  The prey you are hunting is fairly rare and difficult to hunt – you will gain increased rewards. (You now have a term scaling logistically with Estimated Angler Crab Population, see below Rarity of your Quarry)

Hidden effects

•  An occurrence! Your 'Zailing to Sea Zone' Quality is now 2! (hidden)
•  An occurrence! Your 'Ready to chart a course' Quality is now 1! (hidden)

Scaling

The Logistic Scaling for Elusiveness and Rarity are similar, with both having a midpoint of Estimated Angler Crab Population of 25000 and a scaling factor of -1/5000. The difference is that Elusiveness scales to a maximum value of 100, while Rarity scales to a maximum value of 7000. Elusiveness E scales with crab popuation C with the following formula:

$E=100\times {\frac {1}{1+e^{\frac {C-25000}{5000}}}}$

Rarity R scales with crab popuation C with the following formula:

$R=7000\times {\frac {1}{1+e^{\frac {C-25000}{5000}}}}$
