The developmental variations of the sagitta otolith in the young and mature male of a hermaphrodite polynemidae fish, Eleutheronema tetradactylum (Shaw, 1804)

Abstract The Eleutheronema tetradactylum is a protandrous, hermaphrodite, marine perciformes fish.The Glass bottles body length of this fish acts as an important diagnostic marker for male and female discrimination.The present study describes for the first time the ultrastructural characteristics on the medial surface of the sagitta otolith in diff

Unexpected attraction of polarotactic water-leaving insects to matt black car surfaces: mattness of paintwork cannot eliminate the polarized light pollution of black cars.

The horizontally polarizing surface parts of shiny black cars (the reflection-polarization characteristics of which are similar to those of water surfaces) attract water-leaving polarotactic insects.Thus, shiny black cars are typical sources of polarized light pollution endangering water-leaving insects.A new fashion fad is to make car-bodies matt
