Why were sponges originally classified as plants instead of animals?

Sponges were first though to be plants because, at first glance, they appear to be so. They are immobile, have no appendages to speak of, and lack a nervous and circulatory system. What sets them apart from plants, however, are two main things. The first being that they are filter feeders; they siphon water through their bodies and specialized cells with cillia catch the food and transport it to speceialized cells to be digested, whereas the vast majority of plants make their own food. The second is that most sponges start out as free-swimming larvae that eventually settle down onto a solid surface and transform into the sessile soft-bodied creatures we know as sponges.
