Question: What was the name of the orca that killed Dawn Therese Brancheau and that's name is used for several SeaWorld shows?

<P0-S0> Bimbisula ("dawn booby") is an extinct genus of sulid bird known from fossils discovered in Pliocene rocks of South Carolina, United States. <P0-S1>  The type and only named species is "B. melanodactylus". <P0-S2>  The genus name is a combination of the Gullah name "Bimbi", meaning dawn, with "sula", an Icelandic word for "fool" that has been used to describe boobies (Sulidae, "Sula") in general. <P0-S3>  The species name is Greek for "black-fingered", referring to the iron staining that darkened the bones of the type specimen. <P0-S4>  "Bimbisula melanodactylus" is based on Charleston Museum PV2818, a partial skeleton including fragments of the skull, shoulder girdle, left upper arm, right hand, and fused hip vertebrae, and much of the right leg. <P0-S5>  It was collected in 1980 by James Malcolm from a locality along the Seaboard Coast Line Railroad in Charleston County in the vicinity of the Dorchester Road overpass. <P0-S6>  A second specimen assigned to the species, Science Museum of Minnesota P90.38.8, consists of a cranium discovered in October 1990 by Bruce Erickson near the Wando Terminal. <P0-S7>  Both specimens were found in the Goose Creek Limestone, of middle Pliocene age. <P0-S8>  The type specimen comes from the upper part of the formation, which is approximately 3.6 to 3.5 million years old. <P0-S9>  The exact stratigraphy of the second specimen is uncertain, and it may be anywhere from 3.9 to 3.5 million years old. <P0-S10>  "Bimbisula" was a large sulid, comparable in size to smaller species of gannets, and its skeleton shows a combination of booby-like and gannet-like characteristics. <SEP> <P1-S0> Shamu is the name used for several SeaWorld orca (killer whale) shows and is the stage name given to the "star" of those shows, beginning with the original Shamu in the late 1960s and early 1970s. <P1-S1>  The orca Shamu died in 1971, but the name Shamu was trademarked by SeaWorld (as well as the names "Namu" and "Ramu") and has been given to different orcas at different times when performing in Shamu shows. <SEP> <P2-S0>  She worked with orcas at SeaWorld Orlando for fifteen years, including a leading role in revamping the "Shamu" show, and was SeaWorld's poster girl. <P2-S1> Dawn Therese Brancheau (née LoVerde, April 16, 1969 – February 24, 2010) was an American senior animal trainer at SeaWorld. <P2-S2>  She was killed by an orca, Tilikum, becoming the only SeaWorld trainer killed by an animal. <P2-S3>  However, her death was the third fatality associated with Tilikum, and many other trainers have been seriously injured by orcas. <SEP> <P3-S0> Ethelbert was a juvenile killer whale or Orca that surfaced in the Columbia River near Portland, Oregon in October 1931. <P3-S1>  The whale swam 100 miles from the sea up the river. <P3-S2>  Being a rare sighting that far up the river, many sportsmen grabbed rifles and guns and began to shoot the whale to try and kill it for themselves. <P3-S3>  The Governor Julius L. Meier ordered them to stop. <P3-S4>  Some thought the whale was healthy but others thought it was slowly dying and needed to be humanely put down. <P3-S5>  Ed Lessard, a former whaler, and his son Joseph Lessard set out with harpoons and killed the whale, who had gained the name Ethelbert.
