Editing Grimpoteuthis (section)

== Threats ==
Species of ''Grimpoteuthis'' face few direct threats from humans largely due to living at depths of {{Convert|1000|meters|ft}} and below. Natural predators of cirrate octopuses include large [[teleost]] fish and sharks, and even marine mammals such as sperm whales and seals, but these are mostly predators of other cirrate genera''. Grimpoteuthis'' has only been recorded in the stomach contents of a shark.<ref name="Collns-Vllnva-2006">{{Cite journal |last1=Collins |first1=Martin A. |last2=Villanueva |first2=Roger |year=2006 |title=Taxonomy, ecology and behaviour of the cirrate octopods |journal=[[Oceanography and Marine Biology]] |series=Annual Review |volume=44 |pages=277–322 |doi=10.1201/9781420006391.ch6 |doi-broken-date=11 November 2024 |isbn=978-0-8493-7044-1}}</ref>

The ''Grimpoteuthis'' do not have an ink sac (as is the case with all cirrate octopuses). Furthermore, the cirrate octopuses lack innervated chromatophores and therefore are not capable of changing color<ref name=Collns-Vllnva-2006/> (despite some unreferenced statements to the contrary).<ref>{{Cite journal |last=Hadjisolomou |first=Stavros P. |date=March 2017 |title=SpotMetrics: An open-source image-analysis software plugin for automatic chromatophore detection and measurement |journal=[[Frontiers in Physiology]] |volume=8 |pages=106 |doi=10.3389/fphys.2017.00106 |pmc=5331055 |pmid=28298896 |doi-access=free}}</ref>
How cirrate octopuses escape or avoid predators is largely unknown.
