Drepane punctata, commonly known by names such as butterfish, concertinafish, jetto, peppercorn, sickle-fish, silver moonfish, spotted batfish, spotted sicklefish, sicklefish, and spotted spadefish, is a ray-finned fish belonging to the family Drepaneidae, commonly known as the sicklefishes. Its natural distribution extends throughout the Indo-Pacific region.
Appearance
Drepane punctata has a strongly compressed, oval-shaped body, with the body depth exceeding its standard length. The snout has either a straight or slightly concave outline. The snout, cheeks, and preoperculum are without scales, while the lower margin of the preoperculum has a serrated edge.
A fringe of small cirrhi is present on the chin. The mouth is highly protrusible and, when extended, creates a tube that points downward. The jaws contain bands of slender, pointed teeth, while the roof of the mouth has no teeth.
The dorsal fin contains between 8 and 10 spines, with 9 being the usual number, followed by 20 to 22 soft rays. The anal fin is equipped with 3 spines and between 16 and 19 soft rays. In larger adults, the caudal fin is rounded to nearly truncate in shape.
The pectoral fins are elongated and distinctly sickle-shaped, reaching backward as far as the caudal peduncle. A noticeable bump or bony knob is located between the eyes.
The head and body are generally silvery in color, with between 5 and 10 rows of black spots arranged in vertical series across the upper portion of the body. The fins have a dusky yellow coloration. The dorsal and caudal fins become darker toward their outer margins, and they feature two or three horizontal rows of dark spots. Each spot occurs on an individual section of membrane between the soft rays.
The maximum published total length for this species is 50 cm (20 in), although individuals measuring around 25 cm (9.8 in) are more commonly encountered.

The World’s Largest Football Stadiums by Seating Capacity
Before modern stadium regulations introduced all-seater policies, football venues around the globe often held staggering numbers of standing spectators. One of the most remarkable instances was the 1950 FIFA World Cup final between Brazil and Uruguay, when nearly 200,000 fans packed into Rio de Janeiro’s iconic Estadio Maracanã. Though its current capacity is limited to 78,838 seated attendees, it once stood as a symbol of football’s global passion. Today, however, numerous other stadiums surpass it in terms of seating capacity. Here’s a look at the ten largest football stadiums in the world today — and some of them might surprise you.

These delicate flowers bloom during the hottest months of July and August, but each blossom lasts for only around four days. The flowers open in the early morning when the sun rises and gradually close as the afternoon arrives, appearing as if they are resting after their brief display of beauty.
