Big Finner

Big Finner (Balaenoptera physalus) is classified as Endangered (EN) on the IUCN Red List. At high risk of extinction in the wild, with significant population decline and ongoing threats to survival.

<em>Comatricha ellae</em> is a plasmodial slime mold in the class Myxomycetes, order Stemonitidales, belonging to the diverse genus <em>Comatricha</em>. Members of this genus are characterized by their stalked sporangia with a persistent stalk and an elaborate internal capillitial network that aids in spore dispersal. <em>C. ellae</em> has been recorded from Europe and South America, growing on decomposing wood, bark, and other plant debris in moist forest environments. The feeding stage of the organism is a multinucleate plasmodium that migrates across substrates and engulfs microorganisms and organic particles. Upon maturation, the plasmodium aggregates and differentiates into sporangia that release airborne spores. As with other myxomycetes, the species lacks conventional biological traits such as body length or mass, and no quantitative metrics are available. It is not evaluated on the IUCN Red List.
