''T. leonina'' is a little smaller (up to 10cm), but otherwise similar in appearance to ''[[Toxocara canis|T. canis]]''. With a female worm, the easiest way to tell them apart is to cut it open and examine the eggs under the microscope. The eggs of ''Toxoscaris'' are smooth and pale; whilst those of ''Toxocara'' species are dark and pitted.
