A few ctenophores (those in the The Mnemiopsis Genome Project Portal (MGP Portal) is intended as a resource for investigators from a number of scientific communities to obtain genomic information on Mnemiopsis through an intuitive and easy-to-use interface. Curr. Carlton, editor), [14][16] However, a 2015 study applied different methodologies and found support for Porifera as the sister group to all other animals, and confirmed findings from the original study that amino acid alignments gave mixed support for this hypothesis. 49, 143177 (1976). Kohn, A. Curr. Driesch, H. & Morgan, T. H. Zur Analysis der ersten Entwickelungsstadien des Ctenophoreneies. As many as 10,000 eggs are produced from large specimens in areas with abundant prey. Bull. 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.
