Common stingaree

<em>Trygonoptera testacea</em>, commonly known as the common stingaree, is a small elasmobranch fish in the family Urolophidae, endemic to the coastal and estuarine waters of southeastern Australia. This species typically inhabits shallow sandy and muddy soft-sediment habitats in bays, estuaries, and shallow coastal waters along the Australian coastline. Its geographic range is restricted to the temperate waters of southeastern Australia, including areas around Victoria, New South Wales, South Australia, and Tasmania. Classified as Near Threatened on the IUCN Red List, <em>Trygonoptera testacea</em> faces pressures from bycatch in inshore trawl fisheries and habitat degradation of the shallow coastal environments on which it depends. Like other stingarees, the species possesses one or more venomous tail spines used defensively against predators. It is carnivorous, typically feeding on benthic invertebrates including small crustaceans, polychaete worms, and molluscs foraged from soft sediment. The species typically gives birth to live young following viviparous reproduction, a characteristic of the family Urolophidae. Biological traits such as average lifespan in years, precise disc width measurements, and body weight remain poorly documented in the scientific literature for this species.

Rufous-tailed Hummingbird

붉은꼬리벌새(Amazilia tzacatl)는 중앙아메리카와 남아메리카 북서부에서 가장 흔한 벌새 중 하나로, 녹색 상체와 선명한 적갈색 꼬리가 특징인 중형 종이다. 멕시코에서 에콰도르, 트리니다드까지 해발 0~2,100m의 숲 가장자리, 정원, 농장, 2차 성장림 등 다양한 서식지에서 발견된다. 먹이 식물과 급이대에서 영역을 적극적으로 방어하며, 서식 범위 전역의 정원에서 자주 목격된다. IUCN 관심필요종이다.
