Species of the genera Aspidontus and Plagiotremus ( such as the false cleanerfish ) are noted for their cunning mimicry of cleaner wrasses: by imitating the latter's colour, form and behaviour, the blennies are able to trick other fish ( or even divers ) into letting down their guard, long enough for the blennies to nip a quick mouthful of skin or scale.

Species in the genus may be referred to as " pipistrelles " or " pipistrelle bats ", though these terms are also used for species now placed in other genera, such as the western pipistrelle ( Parastrellus hesperus ) and eastern pipistrelle ( Perimyotis subflavus ) of North America.

The two most common systems are the classification adopted by the website AmphibiaWeb, University of California ( Berkeley ) and the classification by herpetologist Darrel Frost and the American Museum of Natural History, available as the online reference database Amphibian Species of the World.

Species are used as food and flavourings ( e. g. onion, garlic, leek, asparagus, vanilla ), as cut flowers ( e. g. freesia, gladiolus, iris, orchids ), and as garden ornamentals ( e. g. day lilies, lily of the valley, Agapanthus ).
