Poraniomorpha abyssicola
(
Verrill 1895
)
Fig. 5C
This species was identified by the highly rugose surface texture, cylindrical arms and the series of actinolateral spines present around the lower edge of the body. This represents the first observation of this species alive and
in situ
. Color in life was white with yellow highlights (
Fig. 5C
).
Poraniomorpha abyssicola
was observed perched on what appeared to be a demosponge on the Blake Ridge dive site at
3403 m
. This is the first observation of this species apparently feeding.
