Entomostraca
Entomostraca is a historical subclass of crustaceans, no longer in technical use. It was originally considered one of the two major lineages of crustaceans (the other being the class Malacostraca), combining all other classes – Branchiopoda, Cephalocarida, Ostracoda and Maxillopoda. The Ostracoda have the body enclosed in a bivalve shell-covering, and are normally unsegmented. The Branchiopoda have a very variable number of body-segments, with or without a shield, simple or bivalved, and some of the post-oral appendages normally branchial. The Copepoda normally have a segmented body, not enclosed in a bivalved shell-covering, fewer than twelve segments, the limbs not branchial. Under the heading Crustacea, the Entomostraca have already been distinguished not only from the barnacles, but also from the Malacostraca.

One Time
by: Stroke 9I gave up 'cause I couldn't feel
And I gave in 'cause it sounded like a steal
Spending time on my back now
Thinking 'bout the facts now
How 'bout this and how about that...
Well here we go
I like to think I'm on top of things
But this life will bring what it will bring, you know
I like to think I'm on top of things
But this life will bring what it will bring
And my less than large brain is contorting the synapses
Sent from the ends of my dangling nerves
Give me just one time
Two times
You know it's where I'm at
I'm waving as I go
I got up, I never thought I'd get there
My mid doesn't mind 'cause my mind won't dare
Wake up, shake up and wind up on my back
How 'bout this and how about that
I wanna wipe the plastic smile off my face
I wanna win without entering the race
I want to say what I mean and mean what I say
I just need something to mean anything
Give me just one time
Two times
You know it's just where I'm at
I'm waving as I go
You gotta give me just one time
Two times
YOu know it's just here I'm at
I'm waving as I go
I just wanna get through
I don't know how I'm gonna do it
