According to National Geographic, 719 animals in the United States are listed as endangered or threatened.

What people may not think about, the site writes, is that endangered species come in large and small. From the regal Bengal tiger to the tiny puritan tiger beetle that can be found here in Connecticut.

The U.S. Fish and Wildlife Service maintains a record of all the endangered species spotted in each state, and as of now, Connecticut has 10 animals on the list.

California has the most with 113 species on its list and Vermont has the least with four, according to National Geographic.

Just this month, federal ocean officials found a dead North Atlantic right whale south of Long Island. The whale is a member of a declining, endangered species.

NOAA says it's the first observed right whale death in U.S. waters this year. Environmentalists and regulators in the U.S. and Canada have kept a watchful eye on the species in recent years, as they have suffered high mortality and poor reproduction. There are only about 400 of the whales remaining, and less than 100 of those are breeding females.

A new report also states that across the United States,there are  3 billion fewer wild birds than there were in 1970.
