He or she is a solitary person in a narrow shell of a boat no more than 12 inches across at its widest point.
The transition between photochemical equilibrium and density profiles determined by advection occurs in a narrow shell 1200 1300 km altitude.
Details of the spectra suggest that the elements glow within a narrow shell of material rifling out from the site of the burst at one-tenth the speed of light.
Children barely out of diapers are let loose to wander the narrow shell lanes, with parents confident that their neighbors will watch out for any stragglers.
It has a weak squishy body that pokes, tongue-like, out of a long, narrow shell with a painfully sharp rim that looks like a closed straight razor (hence the nickname).
Radiating spherulites extended from nucleation sites at the inner shell surface until truncated by crystal growth from adjacent nuclei, forming the slightly flared, narrow shell units.
Extremes on the second RW axis (explaining 3.61% of ventral shell shape variation) were C. pacifica S with a narrow shell bottom (septum) and C. cancapae with a broad septum, respectively.
Similar, though not significant tendencies toward narrower shells were also observed along the second axes (data not shown).
The fast transition within one generation towards narrower shells under laboratory conditions without water current and predation, however, argues rather for phenotypic plasticity of the shell during growth.
