Coastal development for hotels and houses means thereare lots of lights inland. These can confuse the youngturtles and they can head inland towards them.

They also face predatorssuch as this lizard as well asbirds and a variety of otheranimals.

Adult turtles also have a hard time. They face many threatswhile they are in the sea. Unfortunately they face evenmore when they come ashore to lay their eggs. This makesthem vulnerable to a far wider range of threats than manyother animals and plants.

Plastic rubbish is a majorproblem. Turtles eat it inmistake for jellyfish. Itoften ends up killing them.

Those are just some of the threats they face in the sea!There are still more when they try and come up the beachto lay their eggs.

Beaches have sand put on them to replace any washedaway by the sea. This can lead to ledges forming whichturtles cannot climb.

There is one thing everyone can do to help –always get rid of your rubbish properly.

– not just on holiday but also at home. A lot of plastic fromour cities finds its way by river to the sea.

Your rubbish can affect turtles around the coast of Walestoo. There have been sightings of Leatherback Turtles inthe Irish Sea and the Bristol Channel not far from Swansea.

Mae brwydr yn wynebu Crwbanod y Môr o’r dechrau’n deg.Rhaid i’r crwbanod ifanc torri eu ffordd allan o’r nyth adechrau’r daith peryglus i lawr i’r môr.

Mae adeiladu gwestai a thai ar lan y môr yn golygu bodllawer o oleuadau ar y tir. Gall hyn ddrysu’r crwbanod môrifanc a gallant fynd am y tir yn hytrach na’r dŵr.

Mae bywyd yn anodd i grwbanod môr mewn oed hefyd.Mae pob math o fygythiadau yn eu hwynebu yn y môr ac ynanffodus mae mwy fyth o beryglon yn eu hwynebu wrthddod i’r tir i ddodwy. Mae hyn yn eu gadael nhw’n agored iamrywiaeth ehangach o lawer o fygythiadau na’r mwyafrif oanifeiliaid a phlanhigion.

Mae sbwriel plastig ynbroblem fawr. Maecrwbanod môr yncamgymryd y sbwriel amslefrod môr ac yn ei fwyta.Mae hyn yn aml yn eulladd.

Dim ond rhai o’r bygythiadau sy’n eu hwynebu yn y môryw’r rhain! Ac mae mwy o beyglon eto wrth iddynt ddod i’rtir i ddodwy.

Mae pobl yn rhoi tywod ar draethau yn lle’r tywod sy’n caelei olchi i ffwrdd gan y llanw. Mae hyn yn creu silfoedd acnid yw’r crwbanod yn gallu eu dringo.

Mae un peth y gall pawb ei wneud i helpu - sefbod yn gyfrifol wrth gael gwared ar eichsbwriel.– nid dim ond ar eich gwyliau, ond gartref hefyd. Mae llawero’r plastig o’n dinasoedd yn ffeindio’i ffordd i’r môr drwy’rafonydd.

Gall eich sbwriel effeithio ar grwbanod môr oddi ar arfordirCymru hefyd. Mae Crwbanod Môr Lledraidd wedi cael eugweld ym Môr Iwerddon ac ym Môr Hafren, ddim yn bell oAbertawe.
