Fish Anatomy and Adaptations

The virtual field trip at Deering Estate explores fish adaptations through a dissection of the Valley Boot fish. The video covers fish breathing using gills, classification into bony and cartilaginous fish, and the unique features of the Valley Boot, such as its half beak, scales, and countershading. The internal anatomy, including the liver, stomach, and swim bladder, is examined, revealing the fish's primarily herbivorous diet. The video concludes with a conservation message, urging viewers not to remove animals from their natural habitats.
