(2014) were also considered, from which we were able to identify only three transcripts with MIP domain from the Demospongiae Petrosia ficiformis and Chondrilla nucula, and from the Hexactinellid
This interpretation is further supported by the microforaminiferal content, similarly as common hexactinellid
sponges and their preservation, which is indicative of outer-platform to upper-slope environments (Astibia et al., 2014).
fauna of the northwest Atlantic is remaining poorly investigated up to now.

Although Rigby and Albi (1996) described a new species of hexactinellid
sponge from the Puente Formation in Orange County and noted that pelecypods as well as fish were present in the unit, Schoellhamer et al.
Konecki and Targett (1989) found that cod icefish, Lepidonotothen larseni (Nototheniidae), in waters adjacent to the Antarctic Peninsula utilize the spongocoel of the hexactinellid
(glass) sponge Rossella nuda as a substrate on which to deposit their eggs.

Delicate, colorful corals, mother-of-pearl, and hexactinellid
sponges (or glass sponges), such as Venus' flower basket (Euplectella aspergillum), are animals much appreciated for their beauty, although none so much as the pearl of an oyster, the most valuable object by weight and size obtained from an animal.
