Phylum Cnidaria Part 2: Class Hydrozoa

Описание: As we now know, there are five major classes within phylum Cnidaria, and we will go through them one at a time. First up is class Hydrozoa. This contains a variety of small predatory polyps, such as hydras. These are fascinating creatures which can undergo morphallaxis, or tissue regeneration. They also do not senesce, making them biologically immortal. We will also cover other fascinating organisms like siphonophores. There's much to learn, let's get started!
