Corals (Cnidaria; Anthozoa) play critical roles as habitat-forming species with a wide range, from warm shallow-water tropical coral reefs to cold-water ecosystems [1-3]. They also represent complex ecosystem intricate holobionts made up of microbes all domains the Tree Life, where many significant in host health and fitness [4]. The corallicolids are clade apicomplexans that infect variety anthozoans across world, have been shown influence thermal tolerance corals [1, 5]. Despite their...

Extreme functional reduction of mitochondria has taken place in parallel many distantly related lineages eukaryotes, leading to a number recurring metabolic states with variously lost electron transport chain (ETC) complexes, loss the tricarboxylic acid (TCA) cycle, and/or mitochondrial genome. The resulting mitochondria-related organelles (MROs) are generally structurally reduced and most extreme cases barely recognizable features cell no role energy metabolism whatsoever (e.g., mitosomes,...

Most Parabasalia are symbionts in the hindgut of "lower" (non-Termitidae) termites, where they widely vary morphology and degree morphological complexity. Large complex cells class Cristamonadea evolved by replicating a fundamental unit, karyomastigont, various ways. We describe here four new species Calonymphidae (Cristamonadea) from Rugitermes hosts, assigned to genus Snyderella based on diagnostic features (including karyomastigont pattern) molecular phylogeny. also report Calonymphidae,...

Corallicolids are apicomplexan parasites that infect a wide range of corals and related anthozoans. Current global environmental sequencing shows corallicolids tightly associated with coral reef environments, but this sampling is potentially biased against common parasitic strategies, which might lead them to go unnoticed in surveys. We tested the distribution using more focused strategy, by specifically targeting potential anthozoan host animals from cold/temperate marine waters outside...
