What is the most common sea creature in the world?

Answer 1

If you think about the marine food chain you can work this out.

The basic food in the sea is provided by the phytoplankton (single celled plants the float about in the top layers of the oceans). This is eaten by zoo plankton which are very small animals that also float about near the sea surface (except that they swim up at night and down during the day) - everything else living in and from the sea feeds on the zoo plankton or on animals that eat the zoo plankton.

Thus as creatures are animals the most common creatures in the sea and thus the most common sea creature in the world is the zoo plankton.

Answer 2

The copepod is one of the most common sea creatures in the world, comprising a significant portion of oceanic plankton. These small crustaceans play a crucial role in marine ecosystems as a key food source for many marine organisms.
