Tidepool Tim says, "When I go out to collect creatures for study kits - I will throw in a few 'catch of the day' species! These are live creatures, so variation in species (and the number of each) is the nature of building these collections.

If live creatures are not feasible for your classroom, or you'd like to keep the creatures for future classes, this kit can become a collection of preserved marine life that you can use in the classroom or lab whenever you need them. You cannot always use live organisms as they require some planning and upkeep. Once you have a set of these in your display case or in the storeroom they will last for years and be available for student or teaching uses. The specimens have been individually packed in clear plastic jars for easy viewing of key characteristics. Preserved in seawater formalin solutions. Comes with MSDS."
