Answer 1

1. Hector's dolphins are a small and rare species of dolphin that are found only in the waters around New Zealand. They are different from other dolphins in their size, markings, and behavior. They are one of the smallest dolphin species in the world, and they have distinctive black and white markings on their bodies. They are also known for their playful behavior and curiosity towards humans.

2. The population of Hector's dolphins in the waters of New Zealand is estimated to be around 15,000 individuals.

3. Dolphins die when they can't get out of a fishing net because they need to surface regularly to breathe air. If they are trapped in a fishing net, they can drown because they are unable to swim to the surface to breathe. This is a major threat to dolphin populations around the world, as they often get caught in fishing nets accidentally.

4. Plastic bags are a danger to dolphins (and other marine life) because they can be mistaken for food and ingested. If a dolphin ingests a plastic bag, it can block their digestive system and lead to serious health problems or death.

5. If you see a dolphin, you should not try to touch or feed it. Dolphins are wild animals and can be dangerous if they feel threatened or provoked. It is important to respect their space and observe them from a safe distance. If you see a dolphin in distress, you should contact a local wildlife rescue organization for help.
