Question

which type of symmetry do the following animals have, explain the symmetry also: sponges, echinoderms and annelids​

Answer 1

Explanation:

Now that thing has a clear line to cut it down. Five of them, in fact. It's symmetrical down each arm and out the gap on the other side. More than one line of symmetry means it's radially symmetrical. Five lines of symmetry mean it's pentaradial.(echinoderms)

Look at that thing. Is there any line you could cut it along that would give equal halves? No. A sponge is asymmetrical - has no symmetry.( sponges)

There is exactly one line of symmetry on that one - right down that black line. One line of symmetry making two equal halves means bilateral symmetry.( annelids)

Answer 2

Explanation:

sponges- asymmetric

echinoderms- radial symmetry in adult age and bilateral symmetry in larval stage

annelids- bilateral symmetry
