What is Identification of LINE retrotransposons and long non-coding RNAs expressed in the octopus brain about?

## Background Transposable elements (TEs) widely contribute to the evolution of genomes allowing genomic innovations, generating germinal and somatic heterogeneity, and giving birth to long non-coding RNAs (lncRNAs). These features have been associated to the evolution, functioning, and complexity of the nervous system at such a level that somatic retrotransposition of long interspersed element (LINE) L1 has been proposed to be associated to human cognition. Among invertebrates, octopuses are fascinating animals whose nervous system reaches a high level of complexity achieving sophisticated cognitive abilities. The sequencing of the genome of the __Octopus bimaculoides__ revealed a striking expansion of TEs which were proposed to have contributed to the evolution of its complex nervous system. We recently found a similar expansion also in the genome of __Octopus vulgaris__. However, a specific search for the existence and the transcription of full-length transpositionally competent TEs has not been performed in this genus. ## Results Here, we report the identification of LINE elements competent for retrotransposition in __Octopus vulgaris__ and __Octopus bimaculoides__ and show evi
