To make all Laws which shall be necessary and proper for carrying into Execution the foregoing Powers, and all other Powers vested by this Constitution in the Government of the United States, or in any Department or Officer thereof. Section. 9.
Bottlenose dolphins eat several kinds of fish (including mullet, mackerel, herring, cod) and squid. The composition of their diet depends very much on what is available in the area they live in and also on the season.
All dolphins find food by using echolocation, or sonar, and echolocation is especially important to botos on the hunt because visibility is extremely poor in their murky river habitats. A pink dolphin locates a fish by sending out high-frequency sound pulses from the top of its head.
