Introduction
Sea squirts (ascidians, Ascidiacea) are filter feeding marine animals, primitive chordates, that exist in many shapes and sizes. They reproduce by either sexual or asexual (budding) and develop through a laval (tadpole) to an adult phase. Some species have transparent eggs and embryos simplifying developmental imaging.

Some Recent Findings

Early Development
- (b) Ciona intestinalis notochord[4]
Neural
- ascidians lack a segmented hindbrain, but have restricted expression patterns of anterior Hox genes.[5]
