... organisms such as sea anemones and sponges. This study investigated metabolic and behavioral interactions between two-band anemonefish ( Amphiprion bicinctus ) and bulb-tentacle sea anemones ( Entacmaea quadricolor ) at night. We measured the net dark oxygen uptake ( , μmol O 2 h −1 ) of fish–anemone pairs...

... and that this can provide much of the host's total energy. However, it has remained unclear which metabolite(s) are directly translocated from the algae into the host tissue. We reexamined this question in the small sea anemone Aiptasia using labeling of intact animals in the light with 13 C-bicarbonate, rapid...

...V. Haktan Ozacmak; Glyne U. Thorington; William H. Fletcher; David A. Hessinger SUMMARY Cnidocytes, the stinging cells of cnidarians, optimally discharge nematocysts in response to combined physical contact and stimulation of specific chemoreceptors. In the tentacles of certain sea anemones...

...Kwangwook Cho; Ian D. Mcfarlane ABSTRACT Glass microelectrodes were used to record electrical activity from thin rings cut from the column of the sea anemone Calliactis parasitica . This is the first time that pulses have been recorded from the nervous system in the column. Three pulse types were...

...Glen M. Watson; David A. Hessinger ABSTRACT Sea anemones capture prey by discharging nematocysts into them. Chemical and mechanical cues identify suitable prey to sensory receptor systems on the anemone. Conjugated N -acetylated sugars from prey bind to chemoreceptors on cnidocyte/supporting cell...

...Peter E. Pickens ABSTRACT The sand-dwelling sea anemone, Phyllactis concinnata , buries itself by attaching sand grains to the lower column as this is bent under the anemone by a travelling peristaltic wave. Some of the sand is then released as the column expands laterally. Once buried, the anemone...
