A large translucent 'blob' discovered floating off the coast of Cuba has alarmed divers in the area.

But it seems the mystery has been solved.

Rebecca Helm, a PhD student at Brown University, who studies the evolutionary developmental biology of jellyfish, reported in Deep Sea News that they are the eggs of the Diamond-shaped squid (Thysanotheuthis rhombus).

Describing the blob as "the biggest mass of teensy eggs that I have ever seen", she explains that these egg masses can reach up to 1.8m/5'10" in length.

The Diamond-shaped squid can reach 130cm in length and up to 30kg in weight. It is the only species of the family Thysanoteuthidae. The species lifespan is about one year and males and females mature at age 6-8 months.

According to a study by a team of Spanish scientists, who recorded 16 of these egg masses around the Canary Islands from 2000 to 2010, they can contain up to 75,000 eggs.
