The spelling "Dinopis" is also found, but is regarded as an "unjustified emendation".

[1] Spiders in the genus Deinopis catch their prey in an unusual fashion.

[4] These eyes have a wide field of view and are able to gather available light more efficiently than the eyes of cats and owls, and are 2000 times more sensitive to light than human photoreceptors.

[5] This is despite the fact that they lack a reflective layer (tapetum lucidum); instead, each night, a large area of light-sensitive membrane is manufactured within the eyes, and destroyed at dawn, with the membrane being converted into vesicles which are then lysed in the inter-rhabdomeral cytoplasm.

[7] Spiders also lack ears, but Deinopis use hairs and receptors (slit sensillae) on their legs to distinguish sounds at a distance of up to 2 meters.
