Manta Rays are similar to whale sharks, they are both plankton feeders and are migratory animals. If you join a whaleshark snorkel tour in Cancun then you will be sure to encounter these huge creatures along the way. A giant manta ray can grow up to 9 mts but they tend to be smaller in these waters.
Some snorkels have splash guards or valves at the end of the tube to keep water from entering while swimming. A few companies have come up with very sophisticated designs to seal the top of the snorkel as soon as it dips under water, and opens immediately once the intake tube is back up in the air.
