Have you ever seen an orca? These amazing animals are also known as killer whales. Recently, people have spotted them more often in the waters around Northumberland, in the north-east of England. This is very exciting for visitors, business owners, and whale watchers in the area. Scientists think that if big predators like orcas are coming back to an area, it means the water is healthy. One reason for this might be that the waters around the British Islands are getting cleaner and healthier. This means there's more food for all the animals, including the orcas. But some scientists also think that maybe people are just reporting the sightings more often because of social media. Whatever the reason, it's great news for everyone who loves whales and the ocean!
