Another summary phylogeny groups Eresoidea and Palpimanoidea into a single clade, sister to the " canoe tapetum clade " holding the remaining entelegynes.

Amongst the monocots Acorales, the first branching clade has a secretory tapetum, while the other alismatid clade, Alismatales are predominantly plasmodial.
33.
The " tapetum lucidum " enables an animal with it to see in dimmer light than the animal would otherwise be able to.
34.
Within this clade, Polotow et al . place them within a " grate-shaped tapetum clade ", with the family Zoropsidae as their sister:
35.
This is most apparent when the individual is not looking into the camera because the " tapetum lucidum " is far less extensive than the retina.
36.
The eyeshine signature ( from the " tapetum lucidum " in the eye ) of foxes, and body shape and silhouette are used to identify them.
37.
Most animals which possess a " tapetum lucidum " are nocturnal most likely because upon reflection of light back through the retina the initial images become blurred.
38.
Early on in his career, Br�cke was interested in optics, which led him to research the tapetum lucidum of the vertebrate eye and the action of the ciliary muscle.
39.
:: Many animals also have a tapetum lucidum at the very back of their eyes, which reflects light back to the retina to give it a second chance of being detected.
40.
A nocturnal animal, the Bengal slow loris has excellent night vision, enhanced by a tapetum lucidum a layer of tissue in the eye that reflects visible light back through the retina.
