Can you tell us which of the following animals is an invertebrate?
-
Jaguar
-
Jay
-
Jackal
-
Jellyfish
That's Correct!
It's Wrong!
The correct answer is "Jellyfish". Unlike vertebrates, invertebrates do not have a backbone or spinal column. Jellyfish belong to the group of invertebrates known as cnidarians, which also includes sea anemones and corals. Jackal, jaguar, and jay are all vertebrates, with jackals and jaguars being mammals and jays being birds.
