Broadgill Catshark

The Broadgill Catshark (Apristurus riveri) is a species in the genus Apristurus. It is currently classified as Least Concern on the IUCN Red List. Typically found in marine environments from coastal waters to deep ocean.

<em>Comatricha alta</em> is a myxomycete, or plasmodial slime mold, belonging to the order Stemonitidales within the class Myxomycetes. Like all members of the genus <em>Comatricha</em>, it occupies a unique position in the tree of life, exhibiting characteristics that were historically associated with both fungi and protozoa but are now classified within the supergroup Amoebozoa. The species produces fruiting bodies consisting of delicate, thread-like capillitial networks enclosed within a peridium, and forms spores that are dispersed by air currents. <em>C. alta</em> has been documented from Europe, where it occurs on decaying woody substrates such as rotting logs, fallen bark, and dead plant matter in forested and shaded environments. It thrives in moist, humid conditions that support the feeding plasmodial stage, during which it engulfs bacteria, fungal spores, and organic particles. No quantitative biological traits data are available for this species.
