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 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.Valleys come in all sizes and have a variety of names, just like streams. The smallest streams, rills, run in tiny channels also called rills.he bottom end is its mouth. In between, the stream flows through its main course or trunk. Streams gain their water through runoff, the combined input of water from the surface and subsurface. Most streams are tributaries, meaning that they drain into other streams.
