Encyclopedia
Turtles are reptiles of the order Testudines (or Chelonii) characterised by a special bony or cartilaginous shell developed from their ribs and acting as a shield. The order Testudines includes both extant (living) and extinct species. The earliest known members of this group date from 157 million years ago, making turtles one of the oldest reptile groups and a more ancient group than snakes or crocodilians. Of the 327 known species alive today, some are highly endangered.
Turtles are ectotherms—animals commonly called cold-blooded—meaning that their internal temperature varies according to the ambient environment. However, because of their high metabolic rate, leatherback sea turtles have a body temperature that is noticeably higher than that of the surrounding water.
Turtles are classified as amniotes, along with other reptiles, birds, and mammals. Like other amniotes, turtles breathe air and do not lay eggs underwater, although many species live in or around water. — Wikipedia

As soon as I entered Elmina Castle (the dungeons) in Cape Coast in Ghana, I felt haunted by over 400 years of brutality and the enslavement and genocide of millions of African and Indigenous peoples. That violence still impacts the health of Black and Indigenous folks today.

A trio of researchers with the Okinawa Institute of Science and Technology, the Hebrew University and Tiergarten Schönbrunn, Maxingstrasse, has found that giant tortoises are not only trainable, but have long memories. In their paper published in the journal Animal Cognition, Tamar Gutnick, Anton Weissenbacher and Michael Kuba describe training exercises they carried out with the huge tortoises and what they learned from them.
