The nudging, biting and ramming attacks concentrated on the rudders of medium-size sailing vessels sailing at moderate speed, with some impacts on the hulls. A small group of orcas were believed to be responsible, with three juveniles which have been named black Gladis, white Gladis, and grey Gladis identified as present for most attacks.
[76] [79] Competition between orcas and white sharks is probable in regions where their diets overlap. [80] The arrival of orcas in an area can cause white sharks to flee and forage elsewhere. [81] [82] Orcas appear to target the liver of sharks. [76] [79] In one case a single orca was observed killing and eating a great white shark on its own ...

Some aquarium fish and invertebrates also eat live plants. Hobbyists use aquatic plants for aquascaping, of several aesthetic styles.
She shared her tank with common dolphins, pilot whales, and Pacific white-sided dolphins throughout her time at Seaquarium. The refusal to release Lolita, as well as her overall living standards before her passing, have become a symbol for the movement opposing orca captivity for reasons other than medical need.
Scientists saw a male orca kill a juvenile great white shark within minutes last year. The hunting behavior could be a sign of a wider shift in the marine ecosystem.
