The echidnas are sometimes treated as only two species and sometimes treated as 4, 5, or 8 depending on the authority.  Some consider Zaglossus bartoni and Z. bubuensis as subspecies of Z. bruijni.  Likewise, there are variants of Tachyglossus that have also granted species status by some authorities: T. lawesi, T. typicus, and T. setosus.\n\nThe three monotremes are the platypus: Ornithorhynchus anatinus, and the two species of echidna: Tachyglossus aculeata and Zaglossus bruijni. If 5 species are recognzied, the additional two are Zaglossus bartoni and Zaglossus bubuensis.

Mesozoa)\n- Dicyemida: (Prev. Mesozoa)\n- Cnidaria: jellyfish\n- Ctenophora\n- Platyhelmintes: flatworms\n- Nemertea (= Rhynchocoela)\n- Gnathostomulida\n- Rotifera\n- Acanthocephala\n- Micrognathozoa\n- Gastrotrichia\n- Nematoda\n- Nematomorpha\n- Priapula\n- Kinorhyncha (= Echinodera)\n- Loricifera\n- Arthropoda: insects, spiders, crustacea, etc.\n- Annelida\n- Pogonophora\n- Vestimentifera\n- Echiura\n- Sipuncula\n- Mollusca\n- Phorona\n- Ectoprocta (=Bryozoa)\n- Brachiopoda\n- Entoprocta\n- Cycliophora\n- Echinodermata: sea stars, etc.\n\nYou can also include to de list Hemichordata and Cephalochordata.

A hexagon has 6 sides.

An object is symmetrical if it could be cut down the middle and produce two mirror images.  "Bilateral" just means "two sides", indicating that the object is symetrical in one direction.  The term is used in biology, and is a common trait of the animal kingdom.  \n\nFor instance, look at yourself.  You have one eye on either side of your nose, one ear on either side of your head, one arm on either side of your shoulders and one leg on either side of your hips.  If you took a picture of yourself and cut it down the middle, from top to bottom, the two pictures would be mirror images of one another.  This is bilateral symmetry, the same on both sides.

Penguins, bears and seals. Whales. That is a consensus. As for the flaura, lichen ... try looking the remainder up.

lions and tigers are one i know of. aka ligers/tygons. i believe wolves/dogs can be too. i would assume that there could be a lot more possibilities as long as they are in the same family of animal.

hectic question, this ain't maths homework is it?\n\nA regular octahedron has 24 rotational (or orientation-preserving) symmetries, and a total of 48 symmetries including transformations that combine a reflection and a rotation. A cube has the same set of symmetries, since it is the dual of an octahedron.\n\nThe group of orientation-preserving symmetries is S4, or the group of permutations of four objects, since there is exactly one such symmetry for each permutation of the four pairs of opposite sides of the octehedron.\n\nloads more info. on the link below.

Rotifers   are the only I can think of  now if it were Phylum Mollusca it could be Snails, Clams, and squids\n                                 good luck

Star fish have five *arms* (or, sometimes, multiples of five or six arms).  Their legs are called "tube feet" and are found in the grooves under the arms.  They have an even number of them!\n\nMost animals have an even number of legs because they are symmetrical along a single axis, so both sides end up looking the same.  The only way to have an odd number would be to not be bilaterally symmetrical (and the only animals who aren't don't have legs!) or to have a leg in the middle, which wouldn't be much use.\n\nThe only "exception" to this would be an insect-like animal called the springtail.  It's not really a leg, but they do have their abdomen bent over and underneath them.  They use it to spring very high into the air, so you could call it a leg of a sort.  Sprintails are neat.  They are very common, but most people never notice them because they are mostly quite small.

They don't all have a left and a right side.   Those that do are called bilaterally symmetrical.   But some others, like certain jellyfish and many flowers,  are radially symmetrical and still others, --amoebae, for example-- are irregular & not symmetrical at all.
