The lionfish belongs in the nekton group. Nekton are aquatic organisms that are able to swim and move independently of water currents, unlike plankton which are drifters, and benthos which dwell at the bottom of a body of water.
I think it is a Nekton because if it was Benthos it would live on the ocean floor, and Plankton are plants or plant like animals. Alligators swim freely and can't breath underwater.
Benthos is an aggrgation of organisms living on or at the bottom of a body of water: Plankton is a group of drifting organisms, and Nektons are free-swimmers unaffected by tides and currents. Therefore a shark is a Nekton.
There are over 200 species of Scyphozoa, about 50 species of Staurozoa, about 20 species of Cubozoa, and in Hydrozoa there are about 1000-1500 species that produce medusae (and many more hydrozoa species that do not).

Yes, dolphins are considered nekton. Nekton are organisms that are capable of swimming actively in the water column, regardless of the direction of water flow. Dolphins are highly efficient swimmers and can actively move through the water to hunt and navigate.
No, plankton is not a small shrimp. Plankton refers to a diverse group of organisms that drift in the water, ranging from microscopic algae and protozoa to small animals like copepods and krill. Shrimp are larger crustaceans that are not classified as plankton.
Grasshoppers can be classified into the insects group.
Yes and no. Isopoda are a big group of different animal life, some of which are plankton. Some others include regular cockroaches.
Probably in the animal plankton.
Shih Tzu's are classified in the Toy Breed group.
A group made up of drifting plants and animals are called plankton. Plankton is a source of food for many animals such as whales.
