00:01:55
Yes, they have.
00:02:03
They have nerve cells that transmit impulses
00:02:07
impulses between parts of the organism's body. Echinoderms don't have brain. The embryonic
00:02:10
development takes place from the movement the zygote is formed and the embryonic comes
00:02:21
into the existence.
00:02:26
There are a set of glands which function sometimes with both secret and hormones transacting
00:02:31
as part of the nervous system they are called neuroendocrine system they have a network of
00:02:36
nervous consisting of interconnected neurons without a central brain reproduction they have
00:02:43
the two types of reproduction sexual and asexual the sexual is by fragmentation when you cut a

thing of a star fix in the thing you have cut they do a new thing
00:02:56
They are oviparous, which means that they lay eggs.
00:03:02
Embryonic development takes place from the moment the zygote is formed and the embryo comes into existence,
00:03:09
to the moment in which an individual is born.
00:03:18
