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

Context paragraphs:
Dawn Brancheau: Dawn Therese Brancheau (née LoVerde, April 16, 1969 – February 24, 2010) was an American senior animal trainer at SeaWorld.  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.  She was killed by an orca, Tilikum, becoming the only SeaWorld trainer killed by an animal.  However, her death was the third fatality associated with Tilikum, and many other trainers have been seriously injured by orcas.

Shrine of St. Therese, Juneau: Shrine of St. Therese of Lisieux overlooks the Lynn Canal in Juneau, Alaska, US.  Situated on 46 acres, the site contains a stone chapel, crypt, labyrinth, columbarium, lodge, cabin, and retreat.  In 1925, St. Therese was named the patroness of Alaska.  In the 1930s, the Jesuit priest, Father William LeVasseur came up with the idea of a retreat center in her name.  Bishop Joseph Raphael John Crimont provided support for its establishment.  Thousands of stones were used to construct the chapel and other structures, which were gathered by volunteers.  The first mass was held in 1941.

Ulisses (orca): Ulisses (sometimes spelled Ulises or Ulysses) is a male orca who currently lives at SeaWorld San Diego in California.  He was captured on November 7, 1980 at Reydarfjördur, Iceland, when he was approximately 3 years old.  He lived at several parks including the Sædyrasafnid Aquarium in Iceland (November/December 1980), and the Rioleón Safari (December 1980 to June 1983), and Barcelona Zoo (June 1983 to January 1994) in Catalonia, before being transported to SeaWorld in 1994.

Corky (killer whale): Corky (II) is a female captive orca (or killer whale) from the A5 Pod in British Columbia, Canada.  She currently lives at SeaWorld San Diego in California.  Corky (II) received her name after the park's original Corky died in December 1970.  She has been in captivity longer than any other killer whale.

Shamu (SeaWorld show): 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.  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.

Shamu's Deep Sea Adventures: Shamu's Deep Sea Adventures is a video game linked to SeaWorld's popular Shamu orca shows.  The game was released in November 2005 and is available for GameCube, Game Boy Advance, Nintendo DS, PlayStation 2, and Xbox.

Project Narwhal: Project Narwhal is the name of a computer program used by the 2012 campaign by Barack Obama.  It was contrasted in the Mitt Romney presidential campaign by Project Orca, so named because the orca is one of the few predators of the narwhal.

Bimbisula: Bimbisula ("dawn booby") is an extinct genus of sulid bird known from fossils discovered in Pliocene rocks of South Carolina, United States.  The type and only named species is "B. melanodactylus".  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.  The species name is Greek for "black-fingered", referring to the iron staining that darkened the bones of the type specimen.  "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.  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.  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.  Both specimens were found in the Goose Creek Limestone, of middle Pliocene age.  The type specimen comes from the upper part of the formation, which is approximately 3.6 to 3.5 million years old.  The exact stratigraphy of the second specimen is uncertain, and it may be anywhere from 3.9 to 3.5 million years old.  "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.

Shamu: Shamu was a captive killer whale (orca) which appeared in shows at SeaWorld San Diego in the mid/late 1960s.  She was the fourth orca ever captured, and the second female.  She was captured in October 1965 and died in August, 1971 after about six years in captivity.  After her death, the name Shamu continued to be used in SeaWorld "Shamu" orca shows for different whales in different SeaWorld parks.

Ethelbert (whale): Ethelbert was a juvenile killer whale or Orca that surfaced in the Columbia River near Portland, Oregon in October 1931.  The whale swam 100 miles from the sea up the river.  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.  The Governor Julius L. Meier ordered them to stop.  Some thought the whale was healthy but others thought it was slowly dying and needed to be humanely put down.  Ed Lessard, a former whaler, and his son Joseph Lessard set out with harpoons and killed the whale, who had gained the name Ethelbert.
