Blacktail spurdog

The Blacktail spurdog (Squalus melanurus) is a species in the genus Squalus. It is currently classified as Data Deficient on the IUCN Red List.

Coast myall (Acacia binervia) is a small to medium tree or tall shrub in the family Fabaceae, native to coastal and near-coastal regions of New South Wales and Queensland in eastern Australia. It grows in coastal heath, dry sclerophyll woodland, and scrubby vegetation on sandy or rocky substrates, often in association with banksias and eucalypts. Like most Australian wattles, coast myall produces phyllodes—flattened leaf-stalks functioning as leaves—rather than true compound leaves in mature plants. The dark green phyllodes are distinctive, with two main veins, giving rise to the species name binervia. Golden-yellow, spherical flower heads are produced in winter to spring, attracting native bees. The genus Acacia sensu lato encompasses hundreds of species across Australia and globally, many of which play important ecological roles in nitrogen cycling through root symbioses. Coast myall is assessed as Least Concern by the IUCN. It is sometimes planted in coastal revegetation projects for its tolerance of poor, sandy soils, drought, and salt-laden winds.
