The family, genus and two species are characterised by a single row of rugae ( transverse thickenings of the body surface ), numerous testes, and two caeca.

In " A . caeca " the genus name has been abbreviated to " A . " and the species has been spelled out in full.

Zinc, and to a lesser extent nickel, lead, cadmium and silver accumulate in the body wall and the pyloric caeca ( parts of the gut which project into the arms ).

A parasitic turbellarian " Triloborhynchus psilastericola " is often present in the coelom of the starfish and when the worm is approaching maturation, it moves into the pyloric caeca and at the same time loses all its cilia.

""'Melaleuca caeca " "'is a plant in the myrtle M . pentagona " with its purple pom-pom flower heads but it is a smaller shrub with narrower leaves and smaller inflorescences.

In most, the antennae have a retractable membrane at the base ( not in " Parallocorynus " and " Rhopalotria " ), and the alimentary canal has caeca distributed all over at random ( in two clean bundles in Aglycyderini and Metrioxenini ).
17.
The Middle Cambrian fossil " Amiskwia " from the Burgess Shale has been classed as a nemertean, based on a resemblance to some unusual deep-sea swimming nemerteans, but few paleontologists accept this classification as the Burgess Shale fossils show no evidence of rhynchocoel nor intestinal caeca.

""'Lepeta caeca " "', common name the "'northern blind limpet "', is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Lepetidae, one of the families of true limpets.

;1593 February 25 : Pope Clement VIII confirms the Papal bull of Paul III that expels Jews from Papal states except ghettos in Rome and Ancona and issues " Caeca et obdurata " ( " Blind Obstinacy " ) : " All the world suffers from the usury of the Jews, their monopolies and deceit . . . . Then as now Jews have to be reminded intermittently anew that they were enjoying rights in any country since they left Palestine and the Arabian desert, and subsequently their ethical and moral doctrines as well as their deeds rightly deserve to be exposed to criticism in whatever country they happen to live ."
