Sea Lilies - Chronicle of Evolution

By Aradhana Amarnath


We are sea lilies

Resembling a cluster of chillies


We lived in the ocean

In the bottommost portion


We are known to be attractive 

Though we are not so active.


Unlike a few others

We come in many colours

No, we are not flowers

Yet hear about our powers. 


We are Eukaryotes

You better take notes.


Crinoids are our class

With cousins sea stars we surpass

Like them we can regenerate

Yet like flowers we have gametes


We stay rooted to the ocean bed

If you had chased us, we couldn’t have fled


We mean no harm

While moving our feather-like arms

To catch the food that floats by

So in hunger we don’t die.


Homes of many creatures are we

And so we are happy to be.


Surprised be not when I state

We are the origins of chordate

Our peduncle-like tubes

Formed in chordates, the neural tubes


A forest of us existed in history

Now look at our phylogenetic tree

On the ocean animals list

Only about 80 species of us exist.


Minus us, the study of evolution

Cannot have completion

We are a prehistoric treasure

Protecting us is your duty for sure.
