The opening and closing responses of balanomorph barnacles suggest that the barnacle can test the properties of the surrounding medium without placing its mantle cavity in communication with the medium. An investigation of the structure of the mantle tissues at the occludent edges of the opercular valves of Elminius modestusDarwin has revealed a collar of membraneous cuticle which carries a linear arrangement of sensory structures. These receptors are continued into cuticular hairs that project…

The Ultrastructure of a Chemoreceptor Organ in the Head of Copepod Crustaceans

The ultrastructure of the paired nerves, previously called frontal organ or X-organ, in copepod crustaceans was investigated and these nerves are found to contain the dendrites of three types of morpho- logically different sensory neurons.

Cirral Structure of the Pedunculated Marine Barnacle Lepas anatifera L. (Crustacea, Cirripedia) — I. Ultrastructure of the Neuromuscular Apparatus

These first ultrastructural findings of the neuromuscular apparatus which supports rhythmic cirral contraction of Lepas anatifera L. is a common pedunculated marine barnacle with well developed, articulated cirri which gather water-suspended food particles, aid in predatory food capturing and may facilitate respiratory function by creating water currents through the mantle.

A study of the morphology, ultrastructure, and histochemistry of the food of the pediveliger of Ostrea edulis

The grouping of the glands, position of the openings of the cells, and histochemical properties of the secretions suggest that they may be involved in localised and general adhesion of the foot during temporary attachment, as well as in cementing of the larva.

Pyrgoma kuri Hoek, 1913: a case study in morphology and systematics of a symbiotic coral barnacle (Cirripedia: Balanomorpha)

The present study expands knowledge of specializations and understanding of the evolution and relationships of the derived pyrgomatids as well as the archaeobalanines and bryozobiines and finds the complex modifications of the basis evidently function as an avenue for chemical mediation of growth between the barnacle and its host.

Stafford (1913) rejected the view of many early workers that oyster larvae cemented themselves to the substratum with secretions of the mantle edge and suggested that the cement was spread over the shell by the foot, while Nelson (1924) and Cranfield (19736, c) have clarified the role of the foot in cementing.

Prolonged withdrawal: A possible predator evasion behavior in Balanus glandula (Crustacea: Cirripedia)

The reduced response to the non-predatory species indicates that this is not a generalized response to gastropods or asteroids, but rather that it appears to be specific to potential predatory species.

Eco-physiological studies of an intertidal crustacean, Pollicipes polymerus (Cirripedia, Lepadomorpha): aquatic and aerial respiration.

Physiological responses to environmental stresses of the intertidal cirriped Pollicipes polymerus have been studied by combined field and laboratory experiments and the muscle cells show volume regulation, but free amino acids seem to be unimportant in regulation of intracellular osmolality.

The presence of chemoreceptors on the attachment organ of the cypris larva indicates that a chemosensory mechanism could operate during the gregarious behaviour of settling cyprids.

The interrelationship of cirral movements, feeding, and respiratory exchange is traced through the possible course of evolution of cirripedes, to the culmination in the most highly developed group, the Balanidae.

RESPONSES AND ACCLIMATION TO SALINITY IN THE ADULTS OF SOME BALANOMORPH BARNACLES

It is concluded that the barnacles here tested are osmoconformers, able to adjust to small changes of environmental salinity by tissue acclimation, but evading too severe salinity changes by withdrawing into the protection of the shell.

THE USE OF LEAD CITRATE AT HIGH pH AS AN ELECTRON-OPAQUE STAIN IN ELECTRON MICROSCOPY

The stain reported here differs from previous alkaline lead stains in that the chelating agent, citrate, is in sufficient excess to sequester all lead present, and is less likely to contaminate sections.
