Coastal Dung Beetle

Onthophagus nigriventris, the coastal dung beetle, is a scarabaeid beetle in the family Scarabaeidae, subfamily Scarabaeinae, recorded from coastal habitats in the United States. Dung beetles in the genus Onthophagus, comprising over 2,000 species and representing the most species-rich genus of beetles globally, play critical ecological roles as decomposers, burying mammal dung to provision nests in which females lay eggs and larvae develop. By transporting dung underground, Onthophagus beetles contribute to nutrient cycling, soil aeration, secondary seed dispersal from seeds present in dung, and reduction of parasite loads in livestock. The coastal association of O. nigriventris may reflect its association with marine mammal haul-out sites, seabird colonies, or the dung of coastal wildlife such as deer, raccoons, and feral animals in beach and dune systems. The species is assessed as Least Concern by the IUCN. Dung beetle communities have declined significantly in parts of North America and Europe due to widespread veterinary use of ivermectin and related antiparasitic drugs in livestock, which persist in dung and are lethal to beetle larvae developing within treated dung pats.

orque

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
