The rare ctenophore Haeckelia rubra (formerly Euchlora rubra) has long been known to have nematocysts rather than colloblasts in its tentacles. Five specimens were collected in the San Juan Archipelago, Washington State, USA in 1980 and 1981, and their feeding behavior was observed in the laboratory. We found that H. rubra readily eats the tentacles of a medusa, Aegina citrea, whose nematocysts (apotrichous isorhizas) are nearly identical in morphology to the nematocysts of the ctenophore. When… 

In Situ Foraging and Feeding Behaviour of Narcomedusae (Cnidaria: Hydrozoa)

By extending the tentacles perpendicular to the swimming path, these medusae achieve a relatively large encounter area, thus increasing the probability of contact with prey, for the amount of protein invested in tentacles.

Hydra nematocysts in the flatworm Microstomum lineare: in search for alterations preceding their disappearance from the new host

The presented data indicate that acridine orange staining allows the detection of early alterations of all three ingested nematocyst types preceding their disappearance from M. lineare, and support the notion that the transport of venom-loaded stenoteles to the epidermis provides a strategy of excretion.

This account categorizes ctenophore feeding methods using published reports as well as new observations using submersibles and blue-water scuba diving to help explain the high morphological diversity in this relatively small phylum.

Middle Cambrian ctenophores from the Stephen Formation, British Columbia, Canada

The Ctenophora are a marine phylum of gelatinous swimmers and crawlers, with a minimal fossilization potential, but they probably evolved very early in the metazoan radiations, perhaps from an animal with an anterio-posterior axis and a ciliated surface.

Predation among pelagic cnidarians and ctenophores is reviewed. The diets of semaeostome scyphomedusae and hydromedusae commonly include other gelatinous zooplanktivores. However, few species of

Morphology and distribution of a deep- water Narcomedusa (Solmarisidae) from the northeast Pacific

The oral stomach wall contains three prominent rings of tissue and an intermediate ring closer to the mouth than the gonads, and they also overlie the gonadal position where nematogenic tissue extends out to the base of each tentacle.

Intraguild predatory interactions between the jellyfish Cyanea capillata and Aurelia aurita

Behavior observations suggested that predators did not alter their swimming behavior during meals, and thus that feeding rates were generally handling limited rather than encounter limited, and Predators captured more prey than needed, and semi-digested prey was often discarded when fresh prey was encountered.

Euchlora rubra (K6lliker) is known as the only ctenophore provided with nematocysts, and here is another case where nem atocysts of foreign origin simulate their occurrence in an animal outside of the Cnidaria.

On triggering and control of cnidocyst discharge

It is proposed that the cnidocytes of physonect siphonophores can be placed in two categories of receptor‐effectors both sensitive to stimuli received by the cNidocil and connected with the nervous system which may modulate or control their thresholds of excitability.

NEMATOCYSTS OF MICROSTOMA

The fact that the nematocysts of Hydra are distributed uniformly over the surface of Microstoma within 12 hours after a Hydra has been ingested suggests that this is not a process of elimination, but is done in order that the Nemesis may be used.
