Dendronotus sp. photographed by Maureen Dengah
Dendronotus sp. (undescribed)
Members of the family Dendronotidae Allman, 1845 and represented by very few species in tropical waters but to the contrary are incredibly diverse in their morphology. This group is far more populous in temperate cold waters.
Maureen Dengah's specimen shown here is not a perfect match for any of the known species from this region, but is most closely resembles D. regius Pola & Stout, 2008, due to the white body with dark brown marks and similar color on the tips of the "cerata", rhinophores and frontal veil. One contradiction is the lack of red color of the rhinophoral lamellae.
The real kicker however, setting this species apart, is the surface of the dorsum, which is covered with low, bifurcating papillae, absent in D. regius . In fact I am not aware of any species of dendronotid having ramified papillae on its body.
Well it looks like Marta and company have another project on their hands. Too bad it's from Indonesia, where we cannot collect. Good show Maureen!
