There is an imaginary band in the sky called the Plane of the Ecliptic. The planets we can see from earth, never wander above or below that band of sky - so the planets are always in one of the other of the constellations that lie in that band. We call those particular 12 (or 13) constellations the "constellations of the Zodiac".
The zodiac is the collection of constellations around the meridian that are familiar astrological signs (capricorn, virgo, taurus, aries, leo, etc.) There are many constellations in both the northern and southern hemispheres that are not part of the zodiac. Some that you may have heard of in the northern hemisphere include Orion, the big and little dippers (formerly Ursa Major and Ursa Minor), and Cassiopeia.
The twelve signs of the Zodiac are figures of astrology, and represented the star formations through which the Sun, Moon, and five planets passed. (Only Mercury, Venus, Mars, Jupiter, and Saturn are visible to the naked eye.) The constellations with these zodiac names were among those listed by Ptolemy (83 AD - 168 AD). In order of the zodiac calendar : Aries, Taurus, Gemini, Cancer, Leo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. Due to the procession of the equinox, the astronomical constellations are no longer aligned with the signs, notably Capricorn.
The word "asterism" is given to a grouping of stars that is not on the "official" list of 88 constellations maintained by the International Astronomical Union. Also - an asterism is PART of a constellation - like Orion's Belt, The Big Dipper, or a pattern made from the stars of other constellations, like The Summer Triangle, etc.
Yes, Capricorn borders these other constellations: Aquarius Aquila Sagittarius Microscopium Piscis Austrinus

They are all just as common, some are more famous like Leo, Aquarius and other constellations that are on the Zodiac.

The Chinese zodiac is based on a twelve year cycle. The year is lunar based, starting on the second new moon after the winter solstice. The western zodiac and the Amerind earth magic zodiac are based on a twelve month cycle.
No. All circumpolar constellations are found near the celestial poles. Because of their proximity to the poles, they never disappear from view. Sagittarius is on the ecliptic and thus (like all other zodiac constellations) not close enough to the poles to render it circumpolar.
A starfish lives in water-oceans. Stars are glowing things in the sky-they can make constellations.
The zodiac is the "belt" around the sky within which the sun is always located. The moon and planets also always remain in the zodiac or close to it. That's the reason that this part of the sky was long thought to have some special significance with regard to life on earth.
In astronomy Ophiuchus is one of 13 constellations that cross the ecliptic. Ophiuchus has sometimes been considered the 13th sign of the zodiac because the Sun can be seen to pass through the boundary of the constellation November 30 to December 18, according to the International Astronomical Union. The constellations and the astrological zodiac have only a loose association with each other and reality. The zodiac signs in astrology are a means of dividing the ecliptic into 12 equal parts of 30° each, a quadrant encompassing about the distance the Sun travels in a month. Due to the procession of the equinoxes, the tropical zodiac is less accurate astronomically than the sidereal zodiac, which uses the exact placements of the planets in constellations. But neither really encompasses Ophiuchus as a zodiac sign.
The Ecliptic describes our view of the stars in the sky that (approximately) traces out the apparent position of our Sun against distant stars over each year. The area known as the Zodiac is a band about 18 degrees wide centered on the Ecliptic. All constellations are fanciful human interpretations of patterns of stars and galaxies in the night sky. Zodiac constellations are no different than other constellations except that they are patterns in that 18 degree band in the sky. As the Earth moves around the Sun in the plane of the Ecliptic so do the other planets, all at slightly different angles to the plane and with different orbital times so that appear to take the same approximate path as the Sun and our Moon. As the background star patterns change only over millions of years the changing position of the Sun, Moon and planets seem to wander aimlessly about the Zodiac band. The study of these wanderers (Greek planome: I wander) was the forerunner of modern Astronomy and the pseudoscience of Astrology.
They are totally invisible. I cannot see any of them listed. <><><><><> The 12 constellations of the zodiac, which is what I think the question is alluding to, are unique in that they lie on the plane of the ecliptic, i.e. on the apparent path of the Sun with respect to the Earth, as we go through our yearly orbit around the Sun.

A constellation is a group of stars. Nearly all cultures have organised stars into groups because, when see with their surrounding stars, they can outline the vague shape of people, animals or other objects.
