Full Answer

The shark uses its forward momentum to keep swimming. A shark has the ability to change the angle of its fins to alter its direction through the water. A shark must swim constantly or else it sinks to the bottom. Unlike other fish, a shark does not have a swim bladder, an organ that provides buoyancy to other fish. Sharks can swim at great speed and turn quickly when needed.

    How do invertebrates move?

    A:

    Invertebrates use their muscles to move. Most invertebrates have the ability to move, but some do not.

Some invertebrates may move in search of food, but others are stationary and can create their own food.

    How do nematodes move?

    A:

    Nematodes move through the contraction of their longitudinal muscles. There is high internal body pressure when these muscles contract, which causes the body of the nematode to flex instead of flatten. The thrashing caused by this back and forth movement propels a nematode forward.
