Coelenterata is a term encompassing the animal phyla Cnidaria (corals, true jellies, sea anemones, sea pens, and their relatives) and Ctenophora (comb jellies). The name comes from Ancient Greek κοῖλος (koîlos) 'hollow' and ἔντερον (énteron) 'intestine', referring to the hollow body cavity common to these two phyla.

Shetland Ponies have heavy coats and short legs, and are considered quite intelligent. They are a very strong breed, used for riding, driving, and pack purposes.
The meat and milk of the breed are proven through a range of studies to contain far more minerals and healthy fatty acids and far less unhealthy trans fatty acids than conventional modern breeds. [18] [19] [20] Efforts to restore the Shetland breed continue. The Shetland Cattle Herd Book Society continues to protect the breed.

The hemipenis is the intromittent organ of Squamata, [4] which is the second largest order of vertebrates with over 9,000 species distributed around the world. They differ from the intromittent organs of most other amniotes such as mammals, archosaurs and turtles that have a single genital tubercle, as squamates have the paired genitalia remaining separate.

A true endoskeleton is derived from mesodermal tissue. In three phyla of animals, Chordata, Echinodermata and Porifera (), endoskeletons of various complexity are found.An endoskeleton may function purely for structural support (as in the case of Porifera), but often also serves as an attachment site for muscles and a mechanism for transmitting muscular forces as in chordates and echinoderms ...
