"It seems that/like" and "It looks like" are also equivalent, but a verb is expected to follow. -> "Look at that fish, it looks/seems dead", "Look at that fish, it looks like/seems that/like it's dead." On another note, you can also use a noun after "looks like" and "seems like", but not after "seems that" -> "that fish looks/seems like a shark." More @Wikipedia
