While speaking to BBC South East, Mr Reale found a live catshark on Brighton Beach mid-interview and was able to rescue it, nurse it back to strength and return it to the sea.
In 2023, he found a live egg case on Brighton beach, which he hatched at Brighton Watersports and then released the baby shark.
His video documenting this hatching has had 1.3 million views on Instagram.
He said catshark egg cases can wash up during stormy weather and that young sharks that have been caught and released can become disoriented and strand on beaches.
Mr Reale said, so far, there have been three sharks sucessfully reared and released and 200 cuttlefish saved at the Brighton Watersports hatchery.
