Mature from larva to adult

Please take this quick survey to tell us about what happens after you publish a paper. The sexual development of Ephydatia fluviatilis involves a ciliated parenchymula-larva. At this stage the types of cells found in the adult sponge are already present in the larva. The released larva swims around for a while and then, after a period of between 3 and 48 hours, it attaches, usually with the anterior, larval cavity-bearing pole, onto the substratum.

Aphid Nymphs, Instars, Moults & Metamorphosis:

Monarchs, like other insects with complete metamorphosis, undergo a development process that appears very different from humans. They go through stages in which their body form changes radically, whereas human infants have approximately the same form that they will have as human adults. However, we humans do an incredible amount of developing before birth. Insects hatch from the egg at a relatively earlier stage of development, so many of the changes that take place are simply more visible to us.

The pupal stage is found only in holometabolous insects, those that undergo a complete metamorphosis , with four life stages: egg , larva , pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone , prothoracicotropic hormone , and ecdysone. The pupae of different groups of insects have different names such as chrysalis for the pupae of butterflies and tumbler for those of the mosquito family.
