A lank tentacular
appendage gripped the edge of the cylinder, another swayed in the air.
If the righting response of animals in nature is indeed stronger in the sagittal than the tentacular
plane, then one may ask if this behavior is advantageous for ctenophores, and, if so, how.
Like his predecessors, Gates aims to grab hold of what Clement Greenberg once famously called "the umbilical cord of gold" connecting artists and their patrons, and to redirect it in the service of creating new communities, discursive platforms, and networks that have a tentacular
reach (and in which I too have been caught up, not unwillingly: Gates was an intellectual and financial contributor to "Black Collectivities," a conference I co-organized with Museum of Contemporary Art Chicago curator Naomi Beckwith that productively charted many of the questions posed in these lines).
Our protocol was based on tentacular
tissue as a model, because tentacles are generally regions with the highest concentration of nematocysts per area.
Its eyes arc big and its longest tentacular
cirri reaches setiger 11.
Each tentacle can produce an independent longitudinal contraction (tentacular
shortening) and, when coupled with inward bending of the broad tentacular
base (pedalium), will bring the tentacle into the subumbrellar cavity.
Each individual was identified to the lowest taxonomic level by comparison with descriptions available in the literature (Sweeney et al., 1992; Ortiz et al., 2006; Bolstad 2008; Gonzalez et al., 2008; Ortiz & Re, 2010; Uriarte et al., 2010) using standardized morphological characters, including dorsal mantle length (DML, mm), number and distribution of suckers (S), tentacular
club (TC) and chromatophore patterns.
When their movable components are left ajar or opened completely, they erupt into complex tentacular
configurations that take time to understand--particularly in the case of the two-meter-tall versions, which may be installed in relatively small spaces that preclude a distanced, comprehensive point of view.
Antennae and tentacular
cirri shorter than dorsal cirri.
