The Sphynx is a hairless cat with wrinkled skin and large ears. It is better to keep it indoors because it doesn't have fur to keep it warm. The Sphynx is an active cat that likes people and attention. Because it can get oily skin, it needs regular gentle baths or wiping clean.

Squid are sea creatures related to the octopus and cuttlefish, which all have eight legs.
Squid move by sucking water into the top part of their body and squirting it out in a jet. They can also squirt ink into the water to confuse anything that is trying to eat it.
The squid in the photo are being cooked on a barbeque.

A Saint Bernard is a dog originally bred for rescue in the Swiss Alps. They are a large dog, with a large head, and can weigh anything up to 100kg (220 pounds).
St Bernards are prone to many genetic health conditions, such as hip displaysia and turned eyelids, and have a lifespan of only 8 years.
They are loyal and affectionate, but because they are so big it is essential they are well-trained, as such a large dog can knock children down and hurt them if it is boisterous.

A stag is a male deer. Stags can grow a very large set of antlers, which they shed each year.

The starfish, or sea star, is not a fish - starfish have no skeleton. They are related to sea urchins. As they have no skeleton and hence no legs, they don't move around by walking. They move by pumping water around through tubes on the base of their arms. Not all starfish have five arms, some have more.
Starfish eat sea creatures with shells that move slower than it does. Starfish have two stomachs, and one of them can be put outside the starfish's body. So they eat clams and other shellfish by forcing them open and putting their stomach inside the clam's shell.
Some starfish can regrow arms if they are cut off. Some starfish can grow from the cut-off arm as long as some of the central portion of the starfish is still attached.
Starfish send their eggs out to drift into the open sea where they hatch into small swimming larva. When the larva are old enough, they sink to the bottom of the sea and turn into adult starfish.

Stingrays are a type of large fish related to the shark. Stingrays do not lay eggs, but give birth to four or five baby stingrays.
Stingrays have a stinging barb that can be extremely painful, and can sometimes even kill you. The barb often breaks off and stays in the victim. Stingray injuries can be treated with very hot water.

A stork is a large black and white wading bird. They live near wetlands, and they eat insects, frogs, and small fish. Many species migrate to warmer places in the colder months.

The sugar glider is a small marsupial found in Australia and New Guinea that looks like a tiny possum. Sugar gliders have a flap of skin between their front and back legs on both sides that they can stretch out and use to glide. Sugar gliders can jump out of trees and glide through the air to another tree, like a flying squirrel.
Sugar gliders eat the sweet sap of some trees, and some types of nectar.
