Doto sp. #1
|Maximum size: 6 mm.
is a small species with irregularly tuberculate cerata. The body
is transparent to translucent cream. The digestive gland showing
through the cerata is cream and there may be a few white flecks on the
cerata and rhinophore sheaths. The cream coloration is often obscured
by a variable amount of black pigment. (Note 1)
Doto sp. #1 is a
pelagic dendronotid that lives on floating debris, often in association
pinnata. It probably feeds on a small "fussy" hydroid only a few mm
tall that also lives on the debris. Like many species from that
habitat, it clings tenaciously to its substrate. Larger
animals seemed to displace smaller animals while copulating in a dish
and pairs remained resting for some time on newly laid egg masses. Two
to three mm animals laid cream, arc-shaped egg masses about 1 mm across
the arc that hatched in about four days in the laboratory. Some older
masses laid in the field, perhaps by larger animals, had a complete
Maui and French Frigate Shoals: probably also recorded from southern
Japan and Kwajalein.
It was first
recorded from Hawaii off Maui by PF on Nov. 12, 1992.

Observations and comments:
1: When several animals were held
together in a dish on March 25, 2006 dark and light animals were
observed repeatedly copulating with each other supporting lumping the
