Combtooth lantern shark

<em>Etmopterus decacuspidatus</em>, the combtooth lantern shark, is a small deep-sea shark in the family Etmopteridae, assessed as Least Concern on the IUCN Red List. As a member of the lanternshark genus <em>Etmopterus</em>, the species likely possesses bioluminescent photophores along its ventral surface, a characteristic feature of the group used for counter-illumination and possibly intraspecific communication in the deep ocean. The combtooth designation references the multi-cusped tooth structure of the species. Lantern sharks are among the most species-rich shark genera and are distributed across deep oceanic environments worldwide. Specific habitat description and geographic range data are not available for this species in the current record. As with many deep-sea chondrichthyans, comprehensive ecological and biological information is limited. No quantitative biological trait data including body length or weight are recorded for this species.

Red Avadavat

A brilliantly colored small finch of South and Southeast Asia, red avadavats — also called strawberry finches — display deep crimson plumage with white spots across the body in breeding males. They inhabit tall grasslands, reeds, and scrub near water from Pakistan and India east to Indonesia. Popular cage birds across Asia and now established as introduced populations in parts of Europe, Japan, and the Caribbean. They live in flocks and produce quiet, musical calls.
