Modulation of the asymmetry of sea urchin sperm flagellar bending by calmodulin [PDF]
, 1985 Sea urchin spermatozoa demembranated with Triton X-100 in the presence of EGTA, termed potentially asymmetric, generate asymmetric bending waves in reactivation solutions containing EGTA. After they are converted to the potentially symmetric condition by

Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin
The Anatomical Record, EarlyView.Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.
