Source-This post on Three new fish species spotted using tools in the Laccadive Sea is based on the article “Three new fish species spotted using tools in the Laccadive Sea” published in “The Hindu” on 16th April 2024.
Why in the News?
Three fish species in the Laccadive Sea have been spotted using tools.
About the experiment
All three species used live or dead coral structures as anvils to break the hard shells of sea urchins, so they could get to the edible bits inside.
Why does finding matter?
1. Tool usage among fish has predominantly been observed in just 18 species of the wrasse family (Labridae), which vary in size, prey, and location.
2. Reports of chimpanzees using straws to drink water and crows using leaves to retrieve insects from crevices are well-documented. However, there are rare instances of aquatic animals using tools and there is a common perception that fish possess lower intelligence.
3. This study underscores the need for thorough and frequent underwater observations. Such insights are vital for exploring broader questions about animal intelligence and ecological dynamics.
