Wied's marmoset (Callithrix kuhlii) nearly always
has twins that have the unusual characteristic of being chimeric.
Chimeras are organisms that have two distinct genomes. Through the
union of tissue from two separate sources or a mutation in a single
cell or cell group, the individual contains parts of the body that have
different genomes. In Wied's marmosets tissue from one twin can become
part of the body of the other twin, making the latter twin the
pessessor of two genomes: its own genome and the genome of its twin. In
the case of its twin being sired from another male that its father, the
twin can have genetic information from one mother and two fathers.

for sure if it is feral or tame, but he was an interesting addition to
the beach scene. |

unknown bat species, Itacaré, Bahia, Brazil, 2008.
We found this bat in a small cve on the beach. I wish that I knew bat
species better to be able to identify this individual. It was roosting
with several others.

A reserve near Itacare was set to preserve
Atlantic Forest for the golden lion marmoset, but we never saw it. The
Wied's marmoset, on the other hand, was seen on a few occasions.
