Compared to other cnidarians hydromedusea have a thinner and more delicate mesoglae (gelatinous) layer. In the polyp phase, most hydrozoans live colonially and often have polyps that bud from other polyps. Hydra is a solitary freshwater hydrozoan, and its life cycle lacks the medusa and larval stages. In contrast to Hydra, almost all other hydrozoans have complex life cycles, and a majority of them forms colonies. There are two main groups of colonial hydrozoans: thecates (Leptothecata) and athecates (Anthoathecata) (Cartwright et al., 2008).The teacher and class were especially saddened when the colonial hydrozoan died.
