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.

Common hammerhead

The common hammerhead, <em>Sphyrna zygaena</em>, is a cartilaginous fish belonging to the order Carcharhiniformes, family Sphyrnidae. This species is typically found in marine environments and has a distribution that includes the waters of Chile, Denmark, Portugal, Sweden, and Taiwan, reflecting a wide range across both Atlantic and Pacific Ocean systems. As a hammerhead shark, <em>Sphyrna zygaena</em> possesses the characteristic cephalofoil, the laterally expanded head structure that provides enhanced sensory capabilities and hydrodynamic benefits. Hammerhead sharks are generally known to be active, wide-ranging predators within marine ecosystems. No dietary information has been provided for this specific species in current records. Biological traits of this species remain poorly documented in the scientific literature.
