Question

Compare and contrast the lateral line system of fishes with electroreception in sharks.

Accepted Answer

Hello everyone and welcome to today's video. So sharks have special receptors located around their heads that help them search for prey whenever fish hides under the sand, these receptors can detect the fish heartbeat, thus helping the shark locate the prey's location. These receptors among sharks are an example of a given certain numbers of receptors that we could select. Let's begin by answer choice B thermal receptors. These thermal receptors detect changes in temperature here in our question. We have no mention of changes in temperatures that the chart could detect. So these are not going to be a correct answer choice and we're going to cancel it out. Then we have the nose receptors. These are what we call pain receptors and they detect just harmful stimuli that could be affecting the organism. Again here, the shark is not being undergoing any painful stimuli so we're going to cancel is out. And so this lives up with either mecca nor receptors or electro receptors. And the reason why I left this too is these mechanized receptors attacks things like sound waves, which could be what the sharks are using to detect these prey. And these electro receptors detect electrical fields which could also be used by the sharks to detect their prey. Now, I want you to think about this in this way. These electrical fields are going to be created by all organisms and they're usually created by Mosul movement or heartbeats. In the question, we are told that the chart can detect the feature because of its heartbeat. So it is using the heartbeat of the fish to detect the electrical field that it's creating. So what the receptor is is an electoral receptor, because it is relying on their heartbeat to create an electric field and detect that electric field. Because of that, that is going to be the final answer to our question. And the end of the video. I really hope this helped you, and I hope to see you on the next one.
