The Chelonians

From bottom to top:
1. Common Snapping Turtle (Chelydra serpentina)
2. Geometric Tortoise (Psammobates geometricus)
3. Galapagos Tortoise (Dipsochelys dussumieri)
4. Argentine Snake-Necked Turtle (Hydromedusa tectifera)
5. Mata Mata (Chelus fimbriata)
6. Leatherback Turtle (Dermochelys coriacea)
7. Hawksbill Turtle (Eretmochelys imbricata)

The Testidunes (or Chelonii, often called Chelonians) are the reptiles belonging to the order Testudines, and include all of the turtles and tortoises. This order is characterized by their protective bony carapaces, which developed from their ribs millions of years ago. Ribs still line the inside of the shell.

As they’re reptiles, they’re ectothermic, and their body temperature adjusts to the surroundings. They’re all amniotes, as well - that is, they lay eggs outside of the water.

The carapace of most chelonians is covered by bony, overlapping plates, called scutes. However, some species, such as the leatherback sea turtle, have a thick, oily skin covering their carapace instead. Chelonians also have a protective chest plate, called a plastron.

The difference between “turtle”, “tortoise”, and “terrapin” is defined differently depending upon your field and what part of the world you live in. In general, turtles live in either freshwater or the ocean. Tortoises live on dry land and cannot swim. Terrapin is a more specific term for some turtles, referring to the small, edible, hard-shelled turtles.

While all chelonians can be long-lived (as their organs do not suffer age-related decay), large torotoises are the best-known for living over a hundred years. Jonathan, a Seychelles Giant Tortoise, is 183 years old next week, and is the oldest living vertebrate!

Mata mata (Chelus fimbriata)

The Mata mata is a freshwater turtle found in South America, primarily in the Amazon and Orinoco basins. It is strictly an aquatic species but it prefers standing in shallow water where its snout can reach the surface to breathe. The appearance of the mata mata’s shell resembles a piece of bark, and its head resembles fallen leaves. The mata mata is carnivorous, feeding exclusively upon aquatic invertebrates and fish, which it has to swallow whole, since it cannot chew due to the way its mouth is constructed.

Mata mata turtle feeding!

A lot of you guys seemed to like the Mata mata turtle (Chelus fimbriata) (I wrote about it on my blog earlier), so I figured I should show you how a Mata mata is feeding, because I was actually kinda surprised how that looks like. You can imagine it like the Mata mata as a giant vacuum cleaner because thats how it has to feed. It strikes to the fish and sucks the fish in really fast. It has to swallow them whole because of the structure of their mouth (and they dont have any teeth).

[MONSTER] Kamoebas.

Japanese name: カメーバ
Romanized name: Kameeba

Alignment: Yog (Space Amoeba)
Type: Kaiju, giant rock turtle
Inspiration: Turtle
Status: See below.

From: Space Amoeba, Godzilla × Mothra × Mechagodzilla: Tokyo SOS

Trivia

  • In Japanese, a word for a turtle is “kame” (亀).
  • Kamoebas’ scientific name is “megalo matamata.” “Megalo” is a prefix meaning “large” or “great.” In South America, there is a type of turtle known as the matamata (Chelus fimbriat).
  • Space Amoeba and Tokyo SOS share continuity with each other. It was mentioned in the latter movie that the Kamoebas was discovered by Dr. Miya, a biologist in Space Amoeba, on Selgio (also known as Sergio or Selga) Island. In SOS, it was reported that another Kamoebas was seen seventeen years prior.
  • Kamoebas appeared in the television tokusatsu series Go! Godman.
