Gar fish have eggs and larvae that are toxic, serving as a defense mechanism against predators.
The long snouts of gar fish are an evolutionary adaptation for capturing prey and vary depending on their diet.
Gar fish do not have electro-sensing organs but use taste buds on their snouts to detect food and explore their environment.

Gar fish have toxic eggs that are harmful to humans
Gar fish have eggs that are toxic to humans, mammals, and birds, but not toxic to other fish. The toxicity is thought to be a defense mechanism against predators such as invertebrates and birds. The larvae of gar fish are also toxic for a period of time. However, the exact reason for the toxicity of their eggs and larvae is still not fully understood.
Gar fish have evolved long snouts for capturing prey
The long snouts of gar fish are thought to be an evolutionary adaptation for capturing prey. Different species of gar fish have different snout lengths, depending on their diet and the types of prey they feed on. Longer snouts are usually associated with fish-eating species, while smaller snouts are found in species that eat a variety of animals, including fish, invertebrates, and even scavenged food.
Gar fish do not have electro-sensing organs
Gar fish do not have electro-sensing organs like some other aquatic species, such as paddlefish or sturgeon. They do have taste buds on their snouts, which they use to detect food in the water. Their long snouts also allow them to explore their environment and search for food more effectively.
Jeremy Wade's shows like River Monsters have contributed to science communication
Jeremy Wade's shows, such as River Monsters and Dark Waters, have played an important role in science communication by showcasing and raising interest in unique and elusive fish species. While the shows often focus on sensational aspects of the fish, they have helped generate public interest and awareness about these fascinating creatures.
Gar's Evolution and Living Fossil Fallacy
Gar's are slow at evolving compared to other organisms, but they are still evolving. The misconception of them being living fossils is incorrect. They have been evolving over time, although they may appear similar to their ancestors in external appearance. The term 'living fossil' can be used, but with the proper explanation and context.
Conservation Challenges and Gar's Value
Gar's face conservation challenges as they are often misunderstood and targeted as trash fish. People engage in bowfishing and discard them in dumpsters or landfills. However, Gar's play important roles in ecosystems and have value in biomedical research. Promoting their importance and dispelling misconceptions is crucial for their conservation.
November 6-12 is GAR WEEK! What is a gar, you ask? Picture: A long snout. Hundreds of teeth. Scales that could slice you. Should we fear it? Should we hug it? One of the world’s most passionate and knowledgeable experts on this ancient, mysterious fish joins to make you fall in love with these slimy longbois. Dr. Solomon David is affable, charming, enthusiastic and absolutely shameless when it comes to fish puns. Slip into some hip waders and jump in the muck to learn all about a creature that -- despite decades of mudslinging -- is not a gar-bage fish. Also: why gar caviar is a hella bad idea.
