Why do small fish always swim next to large fish?

Question

Whenever I watch a video clip of a shark or a whale. I always see these small fish swimming next to them as if sticking on to them. Why do they do that?

Answer 1

Both pilot fish and remoras accompany large fish like sharks. The remoras actually do stick to the larger fish, by a sort of suction cup on top of their head. The pilot fish do not stick on, they just swim closely alongside. These fish do the shark no particular good, but no harm either. The small fish benefit however in a couple of ways. First, protection. The shark is their "bodyguard". A medium size fish that might eat the smaller fish isn't going to approach a shark. And secondly, when the shark feeds, the smaller fish eat the small scraps from the shark's meal.

Pilot fish get their name from the early belief that they actually guide the shark to food, the way a harbor pilot guides a ship in to port.

Answer 2

confident, of their organic habitat, or an appropriate sized tank, they're particularly rather energetic and swims close to the outdoors. they could nonetheless stay in a constrained area the place maximum different species could die, yet this capability made them to be offered in those betta plastic tank which you spot lots in wal-mart. I inherited a betta from a coworker as quickly as (fish is termed Jungle Bunny), who basically did no longer desire to guard the fish anymore. jointly as living in his prism cup, he remains very nonetheless and basically strikes slightly while fed. yet as quickly as the betta is going into my tank, he will become an avid swimmer! He likes to swim up cutting-edge against the flow from the clear out, dives down, then comes back up in a circle. specially circumstances he will basically flow from side to side alongside the tank besides. He somewhat does have his own character, very energetic yet no longer a bully with the different tankmates. He lived a quite fruitful existence for about 3 years until now passing away.

it`s called mutualism symbiosis.
