Starfish are all head, no body, new study finds

(STRAITS TIMES) – For a long time, scientists have not been able to identify the heads of sea stars, more commonly known as starfish.
A sea star looks like it has five identical arms with a layer of tube-like structures beneath them that help the marine creature move on the sea floor.
But new research suggests that the “arms” are not arms, after all. Genetically speaking, sea stars are largely heads with no torsos or tails.
