Question

Which aquatic organism has five hearts?

Answer 1

The octopus has three hearts.  One main heart and two smaller ones.  I don't know about five hearts, though.  Doing a quick Google search, I only came up with earthworms for animals with five hearts.

Answer 2

Jellyfish ,I have no idea

Answer 3

Your mom

Answer 4

I don't know if this will help but all types of worms, e.g. earthworms have five hearts.

Answer 5

I think it is starfish

Answer 6

Earthworms do...I dunno of any aquatic organisms unless those count.

Answer 7

Euglena..well i am sure for this

Answer 8

i dont think this is possible for an aquatic organism too have 5 hearts unless its a genetic disease. It would be very rare if this existed. maybe someone will prove me wrong though. until that happens i would say its unlikely.
