Coachwhip ray

The coachwhip ray, Urogymnus granulatus, is a large elasmobranch in the family Urogymidae found across the Indo-Pacific region, ranging from the Red Sea and East Africa through South and Southeast Asia to northern Australia and the western Pacific islands. It inhabits shallow coastal waters including coral reef flats, sandy lagoons, seagrass beds, and estuarine habitats, where it forages for benthic invertebrates and small fishes buried in the substrate. The coachwhip ray is characterized by an oval disc and a long, whip-like tail with one or more venomous spines at its base, giving the species its common name. The disc reaches up to 1.4 meters in width, making it one of the larger members of its family. Urogymnus granulatus is ovoviviparous, giving birth to live young after internal development, and has low reproductive rates that make populations slow to recover from exploitation. The species is classified as Vulnerable by the IUCN due to significant declines caused by intensive coastal fisheries across its range, particularly in South and Southeast Asia where it is commonly caught as bycatch or targeted for its valuable meat, skin, and gill plates in local markets. Habitat degradation from coastal development and coral reef decline compounds the threat to wild populations.

Common Echymipera

<em>Echymipera kalubu</em>, the common echymipera, is a spiny bandicoot in the order Peramelemorphia, family Peramelidae, classified as Least Concern by the IUCN Red List. Geographic range data for this species are limited; it is associated with diverse terrestrial and aquatic habitats in its distribution area, which encompasses parts of New Guinea and nearby islands in the Australasian region. Like other members of its family, <em>Echymipera kalubu</em> is a small to medium-sized marsupial with a pointed snout, compact body, and coarse, spiny fur that provides protection against predators. Bandicoots are omnivorous foragers, typically using their elongated snouts to probe soil and leaf litter for invertebrates, plant tubers, fungi, and small vertebrates. <em>Echymipera kalubu</em> is nocturnal and typically solitary, with individuals occupying home ranges in forest, scrub, and disturbed habitats. The species reproduces with a relatively short gestation period, characteristic of marsupials, with young completing development attached to teats within the mother's backward-opening pouch. Bandicoots perform important ecosystem functions as soil disturbers and seed dispersers. Biological traits of this species remain poorly documented in the scientific literature.
