life cycle of sexually reproducing animals may involve indirect ontogenies.Examples of indirect ontogenies are
a. grasshoppers, spiders, mammals, and sharks
b. earthworms, birds and turtles
c. ticks, leeches, squid, octopods, and snakes
d. starfish, crabs, lobsters, conch snails, butterflies, mayflies, frogs, and bony fish
e. lizards, kangaroos, and preying mantids
Indirect ontogeny means that the adult develops from an egg through a distinct larval stages which is very different from the adult and it’s main function is feeding.
Look through your list to figure out which group of animals fulfils this criteria. As a mammal, did you go through a larval stage where you only ate and then metamorphosed into an adult? Does a snake do that? A butterfly? A kangaroo?
