However, because hatchling digits were measured by two different persons (85 and 47 hatchlings measured respectively), we standardized the data by measurer identity, setting the means to zero and the standard deviations to one before pooling the digit measures for analysis.
About 1 out of 1,000 to 10,000 hatchlings will reach adulthood.
They treat, on average, 50 to 70 turtles annually; last year, they released 25 sea turtles and more than 500 hatchlings.

He started a lizard-breeding business at age 15 and sold more than 500 hatchlings online for $15 to $80 apiece.
The laboratory's snook breeding program has also earned worldwide recognition, with nearly 40,000 hatchlings released into Sarasota Bay in the last three years.
