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.
A stream is any body of running water that occupies a channel: it can even be underground in a cave or underneath a glacier. A river is a large surface stream, but other than that there isn't a clear boundary between a stream and a river.Streams smaller than rivers, roughly in order of size, may be called branches or forks, creeks, brooks, runnels and rivulets. The very smallest kind of stream, just a trickle, is a rill. river that meets the sea or a large lake may form a delta at its mouth: a triangle-shaped area of sediment with distributaries flowing across it. The area of water around a river mouth where seawater mixes with freshwater is called an estuary. The land around a stream is a valley.
