Recently some scientists are including the very dissimilar salps under the word-umbrella "jellyfish", but the salps, which are chordate-herbivores in the subphylum Tunicata, and have their own closer-relatives including doliolids, pyrosomes, and appendicularians (larvaceans), are really not jellyfish in any traditional sense of the word. Despite long-standing experimental interest in ctenophores due to their unique biology, ecological influence and evolutionary status, previous work has largely been constrained by the periodic seasonal availability of wild-caught animals and difficulty in reliably closing the life cycle. We also provide protocols for targeted genome editing via microinjection with CRISPRCas9 that can be completed within ~2 weeks, including single-guide RNA synthesis, early embryo microinjection, phenotype assessment and sequence validation of genome edits. light availability, depth and other factors - many oceanic ctenophore J.
