Did you know?
The basket star unfurls its arms into hundreds of branching tips at night to form a living net that traps plankton drifting in the current, then curls back into a tight ball by day.
What defines this group — Echinoderms (starfish, urchins...)
Starfish, urchins and sea cucumbers: a five-fold symmetry found nowhere else in the animal kingdom.
The body is arranged in fives around a centre: no head, no front, no back.
They move on hundreds of tube feet driven by water under pressure.
Many regrow a lost arm; some starfish can rebuild themselves from a single one.
