Chroomonas placoidea is a species of cryptophyte alga in the family Chroomonadaceae, documented from freshwater and aquatic environments in Europe. The specific epithet placoidea may refer to a flattened or plate-like aspect of the cell morphology, from the Greek plakos meaning flat plate. Cryptophyte cells are frequently compressed or dorsiventally flattened, and small differences in cell shape and proportions are important characters for distinguishing species within the morphologically subtle genus Chroomonas. Chroomonas species are characterized by small cell size, typically ranging from five to twenty micrometers in length, with two flagella of unequal length arising from a ventral depression. The plastid occupies much of the cell volume and contains photosynthetically active pigments including chlorophyll a, chlorophyll c, and phycobiliproteins. Chroomonas placoidea contributes to primary production in its freshwater habitat and is part of the diverse microalgal community of European lakes and ponds. Like other cryptophytes, it may engage in mixotrophy under some conditions. The species has not been assessed by the IUCN, consistent with the general treatment of microalgal organisms in conservation frameworks.

Coastal Rocket Frog

Coastal rocket frog (Allobates bromelicola) is a small terrestrial frog in the family Allophrynidae (formerly placed in Dendrobatidae), endemic to coastal lowland forests of Venezuela. Despite its placement near poison dart frogs, Allobates species are non-toxic. This species inhabits the humid leaf litter and bromeliads of coastal Venezuelan forests, where adults care for egg clutches and transport tadpoles to small water bodies including bromeliad phytotelmata. The genus Allobates is widespread across Amazonian and coastal South American forests, characterised by vocal males, ground-level activity, and close parental care. Coastal rocket frog is assessed as Vulnerable by the IUCN, primarily due to restricted range, habitat loss from deforestation for agriculture, livestock grazing, and urban expansion along Venezuela's coast. Climate change poses an additional threat through altered precipitation patterns affecting its bromeliad microhabitats. The species' specific association with bromeliads makes it particularly sensitive to vegetation structure loss. As with many narrowly endemic amphibians, ex-situ conservation programmes and improved habitat protection within its range are considered important management priorities.
