Of the nine species of crayfish in southern Ontario, two are primary or secondary burrowers, four are tertiary burrowers and three have been considered non burrowers. Individuals of all seven species of tertiary burrowers and nonburrowers dug burrows and sealed them when placed in aquaria with mud substrates from which the water was gradually drained. It appears likely that normally nonburrowing species could survive short-term drought by sealing themselves in burrows in the manner more typical of burrowing species.
