* "Orcin" likely refers to an orca, which is a type of dolphin.
* "Orca well" is not a standard term. Perhaps you meant "orca whale"? It's important to use the correct terminology.
* "B is the largest one it feeds on seals c fish?" This part is unclear. It seems like it's asking which is larger, seals or fish, but it doesn't make sense in the context of orcas.
Here's what we can clarify:
* Orcas are highly intelligent and social animals. They are apex predators in their ecosystems.
* Orcas eat a variety of prey, including:
* Seals: Orcas often hunt seals by beaching themselves on the shore.
* Fish: They also eat a wide range of fish, including salmon, herring, and cod.
* Other marine mammals: Orcas are known to prey on whales, dolphins, and even sharks.
To answer the question more accurately, we need to know what "B" refers to.
