The idea that eyespots
evolved as mimics of vertebrate predator eyes dominated discussions of spot evolution for at least a century before biologists began serious tests of the concept, Mappes says.
Below we (1) discuss individual species, including discrepancies with previously reported embryological data, and (2) correct the previous erroneous identification by one of us (JG) of nephrocysts as eyespots
in two species.
Considering how crucial this partnership is, it may be that roving zooxanthellae use their eyespots
to scope out the most desirable digs-a possibility "we think it is quite interesting," Koike said.
Troglochernes omorgus is placed in the Troglochernes as it has four flagellar blades, lacks tactile setae on tarsi III and IV, lacks eyes or eyespots
, has a unicolored carapace with two transverse furrows, and small, dentate, clavate vestitural setae.
funebris should be via planktotrophic larvae, because of the rapid larvae development from small embryos without the propodium and eyespots
, with an embryo diameter mean [+ or -] SD of 86.
No pigmentation except for minute eyespots
and tiny spots near sides of dorsal surfaces of some pereomeres and first pleomere.
He said the butterflies' markings were unusual - both upper and lower sides are silver and the underside of the hind-wing has a row of small eyespots
on this caterpillar are not really its eyes.
The feathers' upper zone of ornaments may intrigue human observers, but big eyespots
there garnered less than 5 percent of the female's time, Yorzinski and her colleagues report July 24 in the Journal of Experimental Biology.
small, on margin, each about 15-18 [micro]m wide.
Washington, April 2 (ANI): The eyespots
of some butterflies serve to both attract mates and ward off predators, according to new research by Yale University biologists.
became apparent, 10 additional embryos were photographed with the eyespot
centrally positioned, and L and W of the pigmented eyespots
(eL and eW, respectively) were measured.
