Explains what fish are and how they differ from other animals, discussing freshwater fish, sea fish, deep-sea fish, shallow-water fish, and sharks, among others.

This book is a comprehensive identification guide to the 222 species of fishes in Florida’s fresh waters. Each species is presented with color photographs, key characteristics for identification, comparisons to similar species, habitat descriptions, and dot distribution maps. Florida's unique mix of species includes some of the world's favorite sport fishes, the Tarpon and Largemouth Bass. This guide also features three species native only to Florida—the Seminole Killifish, Flagfish, and Okaloosa Darter—and the smallest freshwater fish in North America, the Least Killifish. Ranging from the panhandle to the Everglades, their habitats include springs, creeks, rivers, lakes, ponds, swamps, marshes, and man-made canals. As Florida's human population grows, the state's freshwater environments are being changed in ways that threaten its native fishes. This book provides important information on the diversity, distribution, and environmental needs of both native and nonindigenous species, helping us monitor and take care of Florida's water and its aquatic inhabitants.

Nineteenth-century scientist David Starr Jordan built one of the most important fish specimen collections ever seen, until the 1906 San Francisco earthquake shattered his life's work.

Describes how invertebrates are grouped into orders and how each one is different from the rest.

Understanding the world we live in involves understanding the links between living things. This series explains the concept and need for classification. Each book provides key features of each classification group by providing examples of animal and plant classes. All books explain how behavior, life cycle, appearance, and structure link living things within a classification group, such as kingdoms and phyla.

Stock Identification Methods, 2e, continues to provide a comprehensive review of the various disciplines used to study the population structure of fishery resources. It represents the worldwide experience and perspectives of experts on each method, assembled through a working group of the International Council for the Exploration of the Sea. The book is organized to foster interdisciplinary analyses and conclusions about stock structure, a crucial topic for fishery science and management. Technological advances have promoted the development of stock identification methods in many directions, resulting in a confusing variety of approaches. Based on central tenets of population biology and management needs, this valuable resource offers a unified framework for understanding stock structure by promoting an understanding of the relative merits and sensitivities of each approach. - Describes 18 distinct approaches to stock identification grouped into sections on life history traits, environmental signals, genetic analyses, and applied marks - Features experts' reviews of benchmark case studies, general protocols, and the strengths and weaknesses of each identification method - Reviews statistical techniques for exploring stock patterns, testing for differences among putative stocks, stock discrimination, and stock composition analysis - Focuses on the challenges of interpreting data and managing mixed-stock fisheries

Explains what insects are and how they differ from other animals, with an overview of the life cycle of a variety of insects, including ants, bees, cockroaches, grasshoppers, dragonflies, and butterflies.
