Explanation:

Sea turtles are larger in size compared to terrapins (freshwater turtles) and tortoises.

• There are five species in Indian waters i.e. Olive Ridley, Green turtle, Loggerhead, Hawksbill, Leatherback.
• Olive ridley turtles are the smallest and most abundant of all sea turtles found in the world, inhabiting warm waters of the Pacific, Atlantic and Indian oceans.
• The Olive Ridley, Leatherback and Loggerhead are listed as 'Vulnerable' on the IUCN Red List of Threatened Species.
• The Hawksbill turtle is listed as 'Critically Endangered' and the Green Turtle is listed as 'Endangered'.
• They are protected in Indian Wildlife Protection Act of 1972, under Schedule I.

Hence both statements are correct.
