Common animal tracks in the US often come from familiar mammals and birds: deer, raccoons, squirrels, rabbits, skunks, opossums, domestic dogs, coyotes, foxes, bobcats, ducks, geese, beavers, muskrats, and river otters. You may notice them in mud after rain, in fresh snow, along creek banks, on sandy paths, or in soft soil around gardens and … Read more
Learning how to identify animal tracks starts with a simple rule: treat a footprint as a clue, not a final answer. A clear print in mud, snow, sand, or soft soil can tell you the animal’s general size, foot shape, toe count, claw marks, direction of travel, and sometimes its style of movement. It rarely … Read more
Animal tracks and signs are clues wild animals leave behind when they move, feed, rest, dig, nest, or pass through after dark. A single footprint in mud can be interesting, but it is only one piece of a larger story. The best clues usually come from a pattern: where the mark was found, what shape … Read more
Marine protected areas explained in simple terms are parts of the ocean, coast, estuary, or Great Lakes that have extra protections for natural resources, cultural places, or important habitats. Some allow fishing, boating, tourism, research, and other uses. Others are much stricter. The main idea is not just to draw a line on a map, … Read more
Overfishing affects ocean animals by removing fish and other marine life faster than some populations can replace themselves. The most obvious result is fewer target animals, but the damage can spread much farther. Predators may lose prey, prey species may shift out of balance, seafloor habitats can be disturbed by certain gear, and slow-growing animals … Read more
Whales are important to the ocean because they move nutrients, shape food webs, support deep-sea life after death, and can help ocean ecosystems store carbon over long periods. They are not just large animals passing through the water. Their feeding, diving, migration, waste, and carcasses all move energy and nutrients through the sea. The answer … Read more
Sea turtles are endangered or threatened mainly because they face danger in two very different worlds: the beaches where females nest and the ocean where turtles feed, migrate, and grow. Fishing bycatch, loss of nesting beaches, artificial beach lighting, plastic and other marine debris, direct harvest of turtles or eggs in some regions, vessel strikes, … Read more
Bycatch is marine life caught unintentionally while people are fishing for something else. A boat may be targeting shrimp, tuna, swordfish, cod, or another seafood species, but the gear can also catch animals that fishers did not mean to catch. Those animals may be undersized fish, non-target fish, sea turtles, dolphins, whales, porpoises, seabirds, sharks, … Read more
Plastic pollution affects marine animals in several connected ways: animals may swallow plastic, become trapped in it, suffer wounds from it, lose healthy habitat to it, or encounter tiny plastic particles in the food web. The problem is not limited to one famous image of a turtle and a plastic bag. It can involve a … Read more
Coral reefs are important because they give thousands of ocean animals food, shelter, nursery space, and places to hunt, hide, clean, breed, and grow. They also help protect coastlines from waves, support fisheries and tourism, and hold scientific value because reef animals produce unusual chemicals that researchers study. For such small areas of the ocean, … Read more
