Two persons were arrested when they were found to be shifting it to a boat.
They were allegedly planning to smuggle the sea cucumber to Sri Lanka via Dhanushkodi, police said.
About 300 kg of sea cucumber was seized on August 10 by coastal marine police from a boat anchored at Mandapam North Sea here.
Sea cucumber has been classified as an endangered coral species and their harvest is banned under the Wildlife Protection Act.
