Otter – Facts, Features, and Behavior
Otter is a water mammal with brown fur and four legs. It is a carnivore, and its primary food source is fish. Besides eating fish, they take sea urchins, crabs, and mussels as food. Sea Otters are charming and adorable animals. Moreover, there are around thirteen different types of otters around the world. However, there are slight differences between the different species of otters. Sea otters and North American sea otters live in the United States. River otters are much smaller than the sea otters. Around 90% of sea otters in the world live in coastal Alaska.
Furthermore, the otters have the ability to dive deep as 25 feet. They dive deep to find food, and their sensitive whiskers help them to locate small prey. Sea otters breed at any time of the year, and a newborn pup needs continuous attention and care from its mother for six months until it gets survival skills. Moreover, sea otters are one of the few animals that use tools. They use rocks as tools to break their prey and take the flesh out.
Otters face the issue of being hunted, and there are international laws to protect sea otters. Sea otters in the United States received additional protections with the Marine Mammal Protection Act.
Beaver – Facts, Features, and Behavior
Beavers are among the largest rodents in the world. They are famous for building dams across the rivers. Beavers build dams using lodges, tree branches, vegetation, rocks, and mud. They chew down trees to build the dams. By blocking rivers, they create the wetlands they need. Thus, they are capable of changing ecosystems as well. Beavers are hunted for their fur, meat, and castoreum. Nevertheless, they rebounded with protection laws and acts in the 19th and 20th centuries.
Moreover, there are two different types of species of beavers: North American beaver and Eurasian beaver. Beavers are herbivores animals. The average lifespan of beavers is 24 years, and their average weight is 11-32 kg. The tail of a beaver is broad, flat, oval-shaped, and covered with black scales. Beavers do not find different partners for mating. Their offspring helps them when building dams. They get together with the family and make dams across the rivers to have their habitats.
