Which fish tag along with sharks?

There are a few fish that are known to tag along with sharks, but the most famous is probably the remora, also known as the suckerfish.

Here's why they hang out with sharks:

* Free ride and food: Remoras have a special suction disc on their heads that allows them to attach themselves to larger animals, like sharks, whales, and even turtles. This gives them a free ride, and access to food scraps that the shark leaves behind.

* Protection: Being near a shark makes them less vulnerable to predators.

While remoras are the most well-known, there are other fish that occasionally associate with sharks:

* Pilot fish: These fish are often seen swimming alongside sharks, and some believe they have a symbiotic relationship, meaning both species benefit from the association. However, the exact nature of their relationship is still debated.

* Other scavengers: Sharks attract other scavengers due to their feeding habits. Fish like mackerel, tuna, and even smaller sharks might be drawn to the same areas where sharks feed.

It's important to note that these fish aren't necessarily "friends" with sharks. Their association is often based on practical reasons like food, shelter, or protection.
