There are many kinds of animals. Animals can be put into groups based upon their characteristics. Some animals do not have backbones.

Current Events

Gaur (Indian bison) -30,000 left, in India and Southeast Asia -Cloned from skin cells of a male that died 8 years ago -Borne by a surrogate mother cow (1 of 42 implanted, but only 8 became pregnant, one gave birth)

IUCN 2000 Red List of Threatened Species Critically endangered mammals: increased from 169 to 180 in the past 5 years 24% of world’s mammal species threatened 11,046 species of plants and animals are threatened In the past 500 years humans have caused at least 816 species to extinction 103 bird species extinct in the past 200 years

Habitat loss in the Amazon Optimistic and non-optimistic scenarios for forest degradation by 2020.

12% of bird species are threatened 116 species of primates threatened (up from 96 five years ago) Only 15% of reptiles and amphibians have been evaluated (25% are threatened) Only 10% of fish have been evaluated (30% are threatened) Only a fraction of invertebrates have been evaluated Only 4% of plants have been evaluated

A local example of species of concern

Another species of local concern – horseshoe crabs Used for bait in eel and conch traps, and for biomedical research

Blue crab harvests are down and stocks are near historic lows. Crabbers are harvesting smaller crabs, and finding fewer spawning females.

The striped bass (rockfish) fishery is a local conservation success story.
