Final answer:
The question probably refers to an imaginary scenario as orangutans and tigers are not sea-dwelling species but inhabit the rainforests of Borneo and Sumatra and are not known for floating on bananas. Instead, they are threatened by habitat destruction from oil palm plantations.
Step-by-step explanation:
The two species that are referred to in the question are not typical of aquatic or semi-aquatic habitats and would therefore likely not be found floating on a large bunch of bananas in the sea. The species mentioned, such as orangutans (Pongo pygmaeus and Pongo abelii), and Sumatran tigers (Panthera tigris sumatrae), are native to the rainforests of Borneo and Sumatra and are not known for floating or living in sea environments. Instead, they are land-dwelling species that live in dense forest habitats on their respective islands. Rainforests, where these species dwell, are under threat due to deforestation from expanding oil palm plantations. Additionally, some monkeys, such as the proboscis monkey and Allen's swamp monkey, have adapted to aquatic habitats with features such as webbed fingers, but these species are not typically associated with floating on bananas in the sea.
