We will be purchasing Amazonâs Fire TV Stick even though we have the Roku streaming stick. I donât exactly know why, but my husband is jacked about it (especially the price). Fire TV Stick connects to your TVâs HDMI port.
Tetrapod means 4-legged, or, more precisely, 4-limbed. Dogs are tetrapods; so are humans and birds. Fish aren't tetrapods, because they lack arms or legs. However, snakes are considered tetrapods because their ancestors had four legs and were part of the tetrapod lineage.ogs are tetrapods; so are humans and birds.
