What is an animal with 2 nucleus?

Question

My teacher asked me this question

Answer 1

Technically, animals are multicellular heterotrophic eukaryotes, so I don't believe there are any ***animals*** that fit this description.

However, there is a "protist" that does.  So the question you have to answer aside from the one asked is... Does your teacher think that organisms outside of Metazoa (the clade containing ALL animals) are "animals?"  If so, then you've been looking for this protist.

As to which one it is... I usually try not to answer obvious homework questions, but I'll make an exception given the possibility that the original question is somewhat flawed.  

<I>Giardia</i> has two nuclei in its free-living form (four in cyst form).

Answer 2

Okay, I looked everywhere I could for this answer.

At first i googled you question and found the first site on my list of references. Then found out hat all animal cells are eukaryotic, so I googled "eukaryotic organisms with 2 nuclei" but to now avail so I looked on wikipedia. I found that none of the classifications of Bacteria, Fungi, Protists or the other ones had more the one nuclei. But then I remembered that in basic reproduction when one cell meet another they form together to create one cell. During that process ((called IPMAT)) or mitosis, there are 2 nuclei in the cell at a time, until the DNA is combined to reproduce a cell creating a Zygote.

And for that I thank my old Advanced Biology teacher, Seth Foreman =P

Although, I didn't quiet find an "animal" that had two nuclei.

Answer 3

An animal with two nuclei is a single-celled animal that has duplicated its nucleus so it can split into two with one nucleus going to each cell. So, one kind of animal would be an Amoeba, or a Paramecium.

I wonder if the teacher meant to ask what kind of animal has two nucleoli. Or if the teacher meant to ask what kind of animal has two chromosomes.

Answer 4

An animal with two nuclei is an animal with only two cells. There are no animals that exist in this manner for a prolonged period of time, and therefore the only answers to this question are such:

1.) The animal is a newly conceived animal, and the egg has or is about to split for the first time.

2.) Your teacher has made a mistake in asking the question for an animal because animals are typified by our multicellular nature.

I'm not trying to sound mean, but no animal exists with two nuclei, as the nucleus is the control center of the cell, and the second nuclei would cause confusion and cellular chaos. Not to mention that your other cells would most likely recognize the error and attack the "malfunctioned" cell.
