Discicristata

Discicristata is a taxon of unicellular eukaryotes that includes the groups Euglenozoa and Percolozoa. The group was first proposed by Cavalier-Smith in 1998, and is notable for the discoid cristae within their mitochondria.

Classification

The Discicristata are divided into two main groups:

• Euglenozoa
• Percolozoa

The Euglenozoa are further divided into three main subgroups:

• Euglenida
• Kinetoplastida
• Diplonemea

The Percolozoa are divided into two main subgroups:

• Heterolobosea
• Jakobida

Characteristics

Discicristata are characterized by the presence of discoid cristae within their mitochondria. This is a unique feature that distinguishes them from other groups of unicellular eukaryotes. They are also known for their diverse range of lifestyles, which includes both free-living and parasitic species.

Evolution

The Discicristata are believed to have evolved from a common ancestor with the Euglenozoa and Percolozoa. This is supported by molecular data, which shows a close relationship between these two groups.
