Range ~35 (15 to 80) μm/min
Organism Longjaw mudsucker Gillichthys mirabilis

Influences of thermal acclimation and acute temperature change on the motility of epithelial wound-healing cells (keratocytes) of tropical, temperate and Antarctic fish.

Method "Two types of analysis were used to quantitatively describe the directional component inherent in cell velocity. The first type of analysis plots the trajectory of each cell, beginning at the origin and oriented such that the first step taken by each cell is along the x-axis...The second type of analysis, plotting the cos (?) of vectors tangential to the cell trajectory versus path length traveled between each pair of vectors, revealed turning magnitudes in highly persistent cells that were not obvious in the trajectory analysis."
Comments "Keratocytes from G. mirabilis exhibited the greatest size variation. Within a single culture, cells of average size (˜35µm wide along the long axis) could be found along with cells as large as ˜80µm and as small as ˜15µm in width."
