Chaetognaths (arrow worms) have two types of tufts along the body, not previously distinguished. The bristles seen in life are non-sensory processes of epithelial cells. The ciliary tufts visible in sections are groups of sensory neurons each of which bears a non-motile cilium at the tip of its dendrite. The high sensitivity to vibrations set up by a nearby oscillating source in the dark is attributed to the non-motile cilia. The example analysed, Spadella cephaloptera, makes an accurate…

The arrangement of the ciliary sensory organs regularly arrayed on the body is re-described, and it is concluded that these are what are visible as bristles in life. On the head and tail region there

Intracellular recordings from the ring giant axon, which is implicated in escape locomotion, show patterns of facilitating EPSPs correlated with these potentials.

Feeding rates in the chaetognath Sagitta elegans: effects of prey size, prey swimming behaviour and small-scale turbulence

It is suggested that S. elegans is able to separate prey signals from turbulence signals due to their different spatial characteristics.

It is shown that there is probably only a single type of sensory cell amongst the epidermal cells of the body surface and buccal cirrhi; that it synapses at its base with incoming axons of central cells, and that a different type is indeed found in amphioxus, but only in the velar tentacles.

Vibration Perception by Chaetognaths

THE manner in which chaetognaths feed deserves careful examination because they are abundant and cosmopolitan planktonic predators. When these animals feed, they hang motionlessly and then dart at

Experimental Feeding of Some Medusae and Chaetognatha

The feeding behaviour of eight species of medusae was studied; total food consumed, rates of digestion, and growth rate were noted, especially in Cyanea and Aurelia.Aurelia up to 5 cm diam can accept

Diversity of cilia-based mechanosensory systems and their functions in marine animal behaviour

It is envisioned that embracing a broader diversity of organisms could lead to a more complete view of cilia-based mechanosensation, and examples of ciliated sensory cells with a focus on marine invertebrate animals are reviewed.

The Sense Organs and Ventral Ganglion of Sagitta (Chaetognatha)

It is concluded that the arrangement of the peripheral nervous system is unlike that of several groups which have been suggested as related to chaetognaths.

The separate co-ordination of movements of extension, retraction and bending requires that certain types of sensory cells be connected specifically, if in directly, with muscle fibres of a particular directionality, which provides a primitive example of specificity of connexions which must imply two overlapping nerve nets.


The ciliary nature of the photoreceptor cell process in S. scrippsae points to a probable evolutionary relationship of chaetognaths to echinoderms and chordates, and the fine structure and function of these elements of the eye are discussed in relation to earlier studies with the light microscope.

It is stated in a footnote that the reproductive system of Spadella is similar to that of Sagitta, which is regarded as enzyme-secreting cells and the latter as absorptive.
