Manx Whale and Dolphin Watch will be hosting a session later this year.
In 2018, the charity held an event where people could learn all about local whales and dolphins.
Now, MWDW's 2nd show will take place at the Villa Marina in Douglas on the weekend of the 8th and 9th of August.
There will be inflatable, life-size marine species, facts, videos, bones and a kids area.
