In O. dioica, the first polar body is visible 5 min after fertilisation and the second polar body 15 min after fertilisation. O. longicauda individuals can self-fertilise. F. pellucida could not be in vitro fertilised with the same method."]]
Development
-----------
+ - The first and second polar bodies are visible 5 and 15 min after fertilisation,
+ respectively ([[Nishino and Morisawa, 1998|biblio/10.2108_zsj.15.723]]).
- First embryonic cleavages are deterministic and “Clonal organization of the
tissues is essentially invariant among individuals” ([[Stach and coll.,
2008|biblio/18490654]]).
(1980)|biblio/10069_30542]].
- It was already reported to be frequent in Japanese waters [[in 1907 by T.
Aida|biblio/AA0069577]].
+ - _O. dioica_, _longicauda_ and _cophocerca_ April 1997 in Moroiso Bay,
+ Misaki, Miura-peninsula, Kanagawa ([[Nishino and Morisawa, 1998|biblio/10.2108_zsj.15.723]]).
- Oikopleuridae can be found in the deep see. For instance, [[Lindsay and
coll., 2014|biblio/10.1007_978-4-431-54865-2_51]] reported _Oikopleura_, _Mesochordaeus_
and _Bathochordaeus_ individuals in the Hatoma Knoll hydrothermal vent, Okinawa Trough.
