* Nemertines are primarily carnivores but are not scavengers: They typically hunt smaller prey like worms, crustaceans, and mollusks. They have a proboscis, a long, tube-like structure that they can shoot out to capture and paralyze their prey.
* Lack of digestive enzymes for larger prey: While they have digestive enzymes, they are not equipped to break down the large amounts of tissue and fat found in a seal pup.
* Size limitation: Nemertines are generally small, with some species reaching up to 60 feet in length. They are not capable of taking down or consuming prey as large as a seal pup.
Scavenging in the animal kingdom: While some animals are specialized scavengers, like vultures and hyenas, most carnivores primarily hunt live prey. Even if a nemertine were to encounter a dead seal pup, it would not have the necessary adaptations to break down and consume such a large amount of flesh.
Decomposition: The breakdown of a dead seal pup would primarily be handled by bacteria, fungi, and other decomposers in the ecosystem.
In conclusion: It's highly unlikely that a nemertine would be able to digest the flesh of a dead seal pup. Their diet and digestive capabilities are geared towards smaller prey, and they lack the adaptations for scavenging larger carcasses.
