Nubian Flapshell Turtle Research & Conservation

Africa’s rarest turtle is an enigma. The last known individual in captivity died in 2009 in the US, and no turtles had been spotted in the wild for the last 25 years. The C. elegans can reach a shell length of up to 80 cm (31.5 inches), making it the largest species in the genus of flapshell turtles.

The IUCN classified the Nubian flapshell turtle as Critically Endangered during the IUCN Red List workshop in Togo in 2013.

TURTLE ISLAND’S highest priority is to create an ex-situ breeding group, locate the last Nubian flapshell turtles, and protect their habitats.

As there are large gaps in our knowledge about the taxonomy and distribution of C. elegans, we know even less about the biology and ecology of this species. Population composition, diet, and reproductive behavior have not been studied and are not described in scientific literature.

Balance sheet

Fiscal Year: Jan 01 - Dec 31

SOURCE: IRS Form 990 info

The balance sheet gives a snapshot of the financial health of an organization at a particular point in time. An organization's total assets should generally exceed its total liabilities, or it cannot survive long, but the types of assets and liabilities must also be considered. For instance, an organization's current assets (cash, receivables, securities, etc.) should be sufficient to cover its current liabilities (payables, deferred revenue, current year loan, and note payments). Otherwise, the organization may face solvency problems. On the other hand, an organization whose cash and equivalents greatly exceed its current liabilities might not be putting its money to best use.
