What probably explains why coastal and inland garter snakes react differently to banana slug prey?

#Unit 10. Ecological Principles
  1. Ancestors of coastal snakes that could eat the abundant banana slugs had increased fitness. No such selection occurred inland, where banana slugs were absent.
  2. Banana slugs are difficult to see, and inland snakes, which have poor vision compared with coastal snakes, are less able to see them.
  3. Garter snakes learn about prey from other garter snakes. Inland garter snakes have fewer types of prey because they are less social.
  4. Inland slugs are distasteful, so inland snakes learn to avoid them. Coastal banana Slugs are not distasteful.

I. The adrenal medulla does not regenerate, but when the inner two zones of the cortex are removed, a new ZF and ZR regenerate from glomerular cells attached to the capsule.
II. Immediately after hypophysectomy, the ZF and ZR begin to atrophy, whereas the ZG is unchanged because of the action of angiotensin II on this zone. 
III. The ability to secrete aldosterone and conserve Na+ is normal for some time after hypophysectomy, but in longstanding hypopituitarism, aldosterone deficiency may develop, apparently because of the absence of a pituitary factor that maintains the responsiveness of the zona glomerulosa.
