What is is the rarest of all sea turtles?

kemps ridley turtle

The Kemps ridley turtle is the rarest of all sea turtles. It weighs between 80-100 pounds and the mature adult is an olive green color. They nest in large numbers known as "arribadas."

The ridleys have declined significantly in recent years due mainly to predation and poaching and the fact that their nesting areas have dwindled to a single beach near Rancho Nuevo, Mexico. In 1947, 40,000 ridleys nested and in 1981 the number was reduced to less than 500. Ridley turtles dwell in the waters of the North Atlantic and the Gulf of Mexico. On rare occasions, ocean currents have swept ridleys as far as Europe.

Do turtles get stranded like whales?

Stranding is common problem among sea turtles in the northern Atlantic. This can occur when a turtle becomes trapped in northern waters during the winter months. Scientists hypothesize that migration, distribution, and current patterns may influence these entrapments. Frigid water temperatures reduce the turtles' body temperatures below normal and they wash ashore in a condition called cold-stunned. This type of stranding is not unusual and occurs among loggerhead and ridley sea turtles. Each winter, several cold-stunned turtles are rescued from Cape Cod beaches and taken to the New England Aquarium for rehabilitation as part of the Aquarium's Marine Animal Rescue and Rehabilitation program.

Are sharks always hungry?

It has been observed that sharks can go up to approximately 6 weeks without feeding, and the record for a shark fasting was observed with the Swell Shark, in which it did not eat for 15 months. Sharks can enter what is called an "eating phase" in which, yes, perhaps the shark might constitute hunger, but on the grand scale of things, no a shark does not get hungry.

How many senses do sharks have?

Sharks have 8 unique senses. They are hearing, smell, lateral line, pit organs, vision, Lorenzini, touch, and taste. The shark shares many sense that humans do such as taste and smell, but it has three senses that we do not have. The lateral line, pit organs and Lorenzini are senses that have been discovered over the past 10 to 20 years, and play an important role in how the shark functions when swimming around.
