Who are a seahorse's closest relatives?
Even though they are closely related, other members of the seahorse family, the Syngnathidae (sing-NATH-ih-DEE), may look very different. Imagine if you took a seahorse and rolled it out long and skinny. You'd be looking at a pipefish. Now imagine crossing a seahorse with a green, leafy bush and you'd have a pretty good picture of a sea dragon.
