Because an echinoderm's nervous system speaks directly to those special cells embedded in the collagen matrix, telling them when to release their potent catalyst

Now what echinoderms can do, thanks to little cells embedded in their collagen, is those little cells release a compound, and it causes the suspension bridge cable

So ancient echinoderms probably had brains, but modern ones have simple neural nets running from each arm to their mouth in the center.

Other animals like echinoderms use a weird process called maximal indirect development and grow their adult form out of a special ball of cells that have been set-aside.
