Answer 1

1. Scyphozoans spend most of their life cycle as motile carnivores.

Scyphozoans live most of their life cycle as free-swimming, solitary carnivores.

2. The cubozoans only reach sizes up to 15-25cm.

Class Cubozoa includes jellies that have a box-shaped medusa: a bell that is square in cross-section; hence, they are colloquially known as “box jellyfish.”

3. Class hydrozoa has gonads derived from epidermal tissue.

The true characteristic shared by all the diverse species of hydrozoa is that their gonads for sexual reproduction are derived from epidermal tissue, whereas in all other cnidarians they are derived from gastrodermal tissue.
