Similar to shrimp, the jury is still out on whether or not crab is safe to feed to your pet. Thereâs a chance that if fed in small portions, your dog should be fine. However, crab contains a lot of iodine, which many dogs are allergic to. These types of shellfish are fine for dogs to eat in moderation.
A strait is a naturally formed, narrow, typically navigable waterway that connects two larger bodies of water. Most commonly it is a channel of water that lies between two land masses. Some straits are not navigable, for example because they are too shallow, or because of an unnavigable reef or archipelago.
The Waterway has larger locks and deeper drafts than the lower Seaway, limiting large freighters to the four lakes upstream of the Welland Canal and Lake Ontario, and similarly restricting passage beyond the canal by larger ocean vessels. The two waterways are often jointly and simply referred to as the St. Lawrence Seaway, since the Great Lakes, together with the St. Lawrence River, comprise a single navigable body of freshwater linking the Atlantic Ocean to the continental interior.
