This animal was found in a corner of a fish box that was washed up at Porth Kidney Sands, near Hayle, Cornwall, England, United Kingdom.
The fish box also contained Lepas anatifera, the Common Stalked or Gooseneck Barnacle; Prickly Saddle Oyster (Heteranomia squamula); and one or two species of hydroid. The box has therefore probably been washed across the Atlantic from the USA or Canada.
The spherical objects in need of identification ''are not'' plant material or algae.
It has been agreed by experts that they may be eggs; and to expand this they may be either cocoons, cysts or egg sacs. It might be that they are cocoons of marine flatworms, sometimes called flukes, eggs of a type of snail or egg sacs of marine worm.
The close-up images at the top of this page were taken as a result of dissecting the animal. It has to be noted that by the time the species was found and first photographed, a week had elapsed before specimens were collected and the animals had been dessicated by frost and wind. The animal had to be rehydrated prior to dissection and macro photography. The second sequence of shots are of the animal in the state I originally found them; hydrated and mostly covered in a hydroid or similar.
I have placed the images here in case someone recognises the animal in the photos and can get back to me with an identity for it and so it can be recorded to the correct authorities in the UK.
Thank you for any help.

APHOTOMARINE supports open source data recording and sharing for the benefit of wildlife, recorders, research, science and education. The project works closely with the following bodies and organisations.
The Marine Biological Association or MBA, based in Plymouth, is one of the world’s longest-running societies dedicated to promoting research into our oceans and the life they support. Since 1884 the MBA has been providing a unified, clear, independent voice on behalf of the marine biological community.It has a growing membership in over 40 countries.
The CISFBR or Cornwall and Isles of Scilly Federation of Biological Recorders is an independent umbrella organisation supporting independent recorders and recording groups in the county of Cornwall.
The Cornish Biodiversity Network
or CBN is the largest open source wildlife database in Cornwall that sends open source data to the NBN (National Biodiversity Network). It is a new recording system based on the ERICA database, the largest recording resource in Cornwall. The CBN best supports the activities and needs of the independent recording community and recording groups in Cornwall.
The National Biodiversity Network or NBN is a charity that supports open source data sharing and recording supporting conservation, science and education. "Why do recorders need open source?". Simply because it supports the core values of wildlife recording and the free use of records and data over a very wide network that includes partners like the Natural History Museum. The link here is to the NBN Atlas.The link here is to the NBN Atlas.
The taxonomy used here is based on that of the following database, which is also used by the MBA, NHM and the NBN.
The World Register of Marine Species or WoRMS.
