No. A unicellular organism is an organism made up of ONE CELL, so they're all microscopic. Microscopic means that you can't see it it without a microscope. And you can see a sea urchin, so it is not microscopic, so it's not unicellular.

∙ 10y agoNo, arthropods are multicellular, far too large and complex to exist as single cells; or in other words, a unicellular organism could not evidence the arthropod characteristics. The smallest arthropod known is a kind of crustacean - a copepod - at about a tenth of a millimeter long.

Are arthrpods protists?
No. Protists are unicellular, or unicellular organisms which form multicellular structures. Arthropods, including insects, spiders, crabs, lobsters, etc., clearly aren't unicellular. They belong to the kingdom animalia.
Why are arthropods called arthropods?
They express the characteristics inherent to arthropods. All insects are arthropods. Not all arthropods are insects.
Are euglena unicellular or multicellular?
Euglenas are unicellular protists.
Are mammals part of the arthropods?
NO Mammals are not arthropods. Arthropods are insects.
Are Arthropods eukaryotes or prokaryotes?
arthropods are eukaryotic because arthropods are animals.
Is amoeba unicellular or multicellular?
Amoeba is unicellular.
Why are milkweed bugs called arthropods?
They express the characteristics inherent to arthropods. All insects are arthropods. Not all arthropods are insects.
Is a diatom unicellular?
Yes, diatoms are unicellular
Are people arthropods?
No, people are not arthropods.
Are scorpions arthropods?
Yes they are arthropods
Are goats arthropods?
No, goats are not arthropods.
Do arthropods have organs and organ systems?
Yes, they do reflect a high degree of internal organization with organ systems for circulatory, reproductive, digestive and neurological functions to support a sensory array including (in most) vision and (in many) a highly attenuated chemical sense.
