Kookaburra larger group known as "kingfishers", kookaburras are not closely associated with water. The genus "Dacelo" was introduced by the English zoologist William Elford Leach in 1815. The type species is the laughing kookaburra. The name "Dacelo" is an anagram of "Alcedo", the Latin word for a kingfisher. A molecular study published in 2017 found that the genus "Dacelo", as currently defined, is paraphyletic. The shovel-billed kookaburra in the monotypic genus "Clytoceyx" sits within "Dacelo". Four species of kookaburra can be found in Australia, New Guinea, and the Aru Islands. Kookaburras are sexually dimorphic. This is noticeable in the blue-winged and
Kookaburra III during the 101 races of the defender selection series. The end of the selection round robins series found "Kookaburra III" the leading yacht, with 83 points, followed by "Australia IV" at 77 and "Kookaburra II" at 70. "Steak and Kidney" was eliminated on points halfway through the final round. With ongoing protests over the legality of "Australia IV"'s balloon jib, an agreement was reached in which "Australia IV" and "Kookaburra III" would race in a best of nine set. The winning syndicate could then use "Kookaburra II" as the defender yacht if they so chose. Keel modifications to "Kookaburra III"
