Wasp
The largest social wasp is the Asian giant hornet, at up to in length. The various tarantula hawk wasps are of a similar size and can overpower a spider many times its own weight, and move it to its burrow, with a sting that is excruciatingly painful to humans. The solitary giant scoliid, "Megascolia procer", with a wingspan of 11.5 cm, has subspecies in Sumatra and Java; it is a parasitoid of the Atlas beetle "Chalcosoma atlas". The female giant ichneumon wasp "Megarhyssa macrurus" is long including its very long but slender ovipositor which is used for boring into wood and inserting eggs. The smallest wasps are solitary chalcid wasps in the family Mymaridae, including the world's smallest known insect, "Dicopomorpha echmepterygis" (139 micrometres long) and "Kikiki huna" with a body length of only 158 micrometres, the smallest known flying insect.
Humphead wrasse
The humphead wrasse is the largest living member of the family Labridae. Males are typically larger than females and are capable of reaching lengths of up to 2 meters from tip to tail and weighing up to 180 kg, but the average length is generally a little less than 1 meter. Females rarely grow larger than one meter in length. This species of fish can be easily identified by its large size, thick lips, two black lines behind its eyes, and the hump that appears on the forehead of larger adults. The color of the humphead wrasse can vary between a dull blue-green to more vibrant shades of green and purplish-blue. This particular reef fish prefers to live singly but adults are occasionally observed moving in small groups.
