A scientist and university academic described as 'warped and sadistic', a Facebook groomer, and a man in a position of trust are just some of the paedophiles that were jailed this year.
While this doesn't include every paedophile that has been arrested or convicted this year, we name and shame the individuals that have been jailed and that the News has reported on.
Here are a list of the paedophiles that were imprisoned this year:
Prolific paedophile Dr Matthew Falder was jailed for 32 years on February 19 after blackmailing a string of vulnerable victims, many teenagers, into carrying out depraved sexual and physical acts.
The Cambridge graduate admitted 137 offences against 46 victims, male and female, blackmailing one into licking toilet seats, a used tampon, and eating dog food.
He encouraged the rape of a two-year-old boy, and fitted secret cameras in a toilet for sexual gratification.

When police arrested Cambridge graduate Falder and reeled off the offences, he quipped it sounded "like the rap-sheet from hell".
The former Birmingham University geophysics researcher, also traded vile and depraved indecent images and videos online with a father, for images of him raping and torturing his young son.
On another occasion, Falder told the male, who cannot be identified for legal reasons: "I am really looking forward to this evening's pictures."
Eugene Ayres, 61, of Rowan Close, Wisbech, used a messaging app to groom and then sexually assault a school girl before being locked up.
He was in a position of trust, and began grooming the girl on New Year's Day 2016 through a messaging app – gaining her trust and growing a friendship.
The girl's mum found the messages and banned them from contacting each other, but they started messaging each other again shortly after using fake names.
Ayres then began sending suggestive and sexually explicit content, before arranging to meet the girl to engage in sexual activity.
The girl disclosed the assault to a teacher and Ayres later handed himself in at a police station. He pleaded guilty at an earlier hearing to two counts of sexual activity with a child.
He was sentenced to 40 months in prison on March 8.
Michael Lee, of Gonville Place, Cambridge, is a 20-year-old who used Facebook to groom and then sexually assault a young girl.
He began grooming the 11-year-old girl in December 2016 after contacting her on the social media site.
Within a week Lee had convinced the girl they were friends, gained her trust and then started sending 'sexually explicit content'.
He then persuaded the victim to meet him in a Cambridgeshire park and assaulted her by touching her sexually.
Days after the abuse, the girl's parents checked her phone because they were concerned about her behaviour.
They found what police called 'concerning content'.
He pleaded guilty to meeting a girl under the age of 13 following grooming and assaulting a girl under 13 by touching.
Lee was sentenced to 16 months in a young offenders institution, was given a sexual harm prevention order and placed on the sex offenders register, both for 10 years.
Ian Johnson, 59, of Eastgate, Peterborough, was jailed for 11 years after sexually abusing a 7-year-old boy more than 25 years ago.
The court heard in Johnson's trial how he bought the victim sweets to win his trust before abusing him up to a couple times a week.
The boy was convinced by Johnson the abuse was normal at the time and only realised it was wrong when he went to secondary school.
Johnson was sentenced to five years and eight years for the charges of indecent assault on a boy under the age of 14, 18 months for gross indecency with a boy under the age of 14 and 11 years for buggery with a boy under the age of 16, to be served concurrently.
He was also handed an indefinite Sexual Harm Prevention Order.
Michael Carter, 58, of Lode Way, Chatteris, sexually assaulted a young girl and was imprisoned for a year.
He preyed on his victim over a five-year period.
He was found guilty of sexual assault of a child under 13, two counts of sexual assault, exposure and sending communications with intent to cause distress or anxiety.
Peterborough Crown Court heard how Carter's victim told a social worker of his sick behaviour in August 2016.
Carter had touched her, made sexual comments and gestures, exposed himself and sent naked pictures to the young girl.
