What physical characteristic develops in lobsters thriving in consistently colder Canadian waters?
Answer
Denser and harder shells
The consistent presence of colder water temperatures, especially further north in areas like the Gulf of St. Lawrence, influences the exoskeletal structure of the lobsters inhabiting those regions. Lobsters thriving in this environment develop shells that are noticeably denser and harder when compared to those from slightly warmer environments. This increased shell density is structurally significant, as it directly correlates with extended survival times outside the water, providing a practical benefit for long-distance transport, though this density is sometimes thought to correlate with meat that is slightly less sweet.
