A species-specific title for the Nature category, this title tells the reader everything they need to know about these unique underwater predators and their role in the ocean world. Content includes: how shark attacks occur, where and when typically, and some practical survival tips if you happen to be in an area where they're lurking; how sharks fit as apex predators in the ocean realm -- without them, their normal prey would flourish, creating an egregious imbalance that would slowly but certainly collapse the hardy ecology of marshes, reefs and open-ocean habitats; how the sleek, fusiform shape of sharks helps them in their environment and the to sensory modalities specific to the species -- electroreception and mechanoreception -- helping them navigate, find their prey and sense vibrations in the water; plus sharks' biology, anatomy, pysiology, behavior and future in an unknown world were coral reef is doomed to become a thing of the past, traditional fishing killing off entire species of sharks, and how humans effect ecology today.
