He's a contender. This giant burrowing cockroach made the news for (potentially) being the world's heaviest insect. Related to, but not the same as the roaches we see stateside, these creatures can range from 1 to 1.5 ounces
While it's not yet certain if Heathcliff measures up to the title, I'm torn between wanting to look away . . . and not being able to! As it turns out, in Australia, these popularish pets can cost up to 100 Australian dollars (about $85 in US) for two! They give birth to live young, care for babes in a burrow, and dine on easily attained fresh leaves — would you wish for one as a pampered pal, too?
