<P0-S0> Juvenilia; or, a Collection of Poems Written between the ages of Twelve and Sixteen by J. H. L. Hunt, Late of the Grammar School of Christ's Hospital, commonly known as Juvenilia, was a collection of poems written by James Henry Leigh Hunt at a young age and published in March 1801. <P0-S1>  As an unknown author, Hunt's work was not accepted by any professional publishers, and his father Isaac Hunt instead entered into an agreement with the printer James Whiting to have the collection printed privately. <P0-S2>  The collection had over 800 subscribers, including important academics, politicians and lawyers, and even people from the United States. <P0-S3>  The critical and public response to Hunt's work was positive; by 1803 the collection had run into four volumes. <P0-S4>  The "Monthly Mirror" declared the collection to show "proofs of poetic genius, and literary ability", and Edmund Blunden held that the collection acted as a predictor of Hunt's later success. <P0-S5>  Hunt himself came to despise the collection as "a heap of imitations, all but absolutely worthless", but critics have argued that without this early success to bolster his confidence Hunt's later career could have been far less successful. <SEP> <P1-S0> Bender "Ben" Johnson Jr. (May 22, 1939 - March 31, 2014) was an American Makah politician and fisheries expert. <P1-S1>  He served as the chairman and member of the Makah Tribal Council from 1998 until 2000 and from 2001 until 2007. <P1-S2>  He was chairman of the Makah during the first successful hunt of a Pacific gray whale in 1999. <P1-S3>  The 1999 hunt, which took a 30-ton 30 1/2-foot female gray whale, was the first harvest of a whale by the Makah since the 1920s. <P1-S4>  Johnson supported the hunt, which drew worldwide attention and controversy. <SEP> <P2-S0> The gray whale ("Eschrichtius robustus"), also known as the grey whale, gray back whale, Pacific gray whale, or California gray whale is a baleen whale that migrates between feeding and breeding grounds yearly. <P2-S1>  It reaches a length of 14.9 m , a weight of 36 t , and lives between 55 and 70 years. <P2-S2>  The common name of the whale comes from the gray patches and white mottling on its dark skin. <P2-S3>  Gray whales were once called devil fish because of their fighting behavior when hunted. <P2-S4>  The gray whale is the sole living species in the genus Eschrichtius, which in turn is the sole living genus in the family Eschrichtiidae. <P2-S5>  This mammal descended from filter-feeding whales that appeared at the beginning of the Oligocene, over 30 million years ago. <SEP> <P3-S0> Callulops robustus (commonly known as Boulenger's callulops frog or robust frog) is a species of frog in the Microhylidae family. <P3-S1>  It has traditionally been considered as wide-ranging species found in both Western New Guinea (Indonesia) and Papua New Guinea. <P3-S2>  However, it is likely that specimens from the type locality, Misima Island, and New Guinea represent different species. <P3-S3>  If so, name "Callulops robustus" belongs to the Misima Island species, and the mainland species is unnamed. <P3-S4>  Other island populations may or may not belong to "Callulops robustus". " <P3-S5> Callulops microtis" from the mainland has already been removed from synonymy with "Callulops robustus".
