Have you ever heard of a fish that builds nests? Meet the engineer goby, a remarkable fish that constructs elaborate nests to attract mates and protect their young. These nests are not just simple piles of sand or rocks; they are intricate structures that can be as large as a basketball.

What is an Engineer Goby?

The engineer goby (Pomatoschistus microps) is a small fish found in the Mediterranean Sea and the eastern Atlantic Ocean. It is a bottom-dwelling fish that typically lives in shallow waters near rocky shores. Engineer gobies are known for their unique nesting behavior, which involves the construction of elaborate nests made of sand, shells, and other materials.

How Do Engineer Gobies Build Their Nests?

Engineer gobies begin building their nests in the spring when the water temperature starts to rise. The male goby selects a suitable location, usually a flat area of sand or gravel, and begins to dig a hole. He uses his mouth and fins to move the sand and create a circular depression. Once the depression is deep enough, the goby starts to collect materials to build the nest. He gathers small stones, shells, and other objects from the surrounding area and places them around the edge of the depression. He also collects seaweed and other plant material to line the nest.

Why Do Engineer Gobies Build Nests?

Engineer gobies build nests for two main reasons: to attract mates and to protect their young. The nests serve as a place for the female goby to lay her eggs and for the male goby to guard the eggs and fry. The nests also provide shelter for the young gobies, protecting them from predators and the elements.

How Long Do Engineer Gobies Stay in Their Nests?

Engineer gobies typically stay in their nests for several weeks. The female goby will lay her eggs in the nest, and the male goby will guard the eggs until they hatch. Once the eggs hatch, the fry will remain in the nest for a few weeks until they are large enough to swim and feed on their own. After the fry leave the nest, the male goby will abandon it.

Engineer Goby Nests: A Unique Adaptation

Engineer goby nests are a unique adaptation that helps these fish to survive and reproduce in their challenging environment. The nests provide a safe place for the female goby to lay her eggs and for the male goby to guard the eggs and fry. The nests also provide shelter for the young gobies, protecting them from predators and the elements.

Engineer Gobies and Humans

Engineer gobies are not typically targeted by humans for food or sport. However, they are sometimes caught as bycatch in fishing nets. Engineer gobies are also popular aquarium fish, and they can be found in many public aquariums around the world.
