They got in too deep.
unknown class of large marine bioconstruct. size unclear, but teeth lodged inside one of our aerobuli crafts suggest length of approximately 50 metres if estimates are correct. historical evidence and excavated remains suggest even larger bioconstructs, such as the svl.bst-landcarrier, but sea-based. no evidence of flying megaconstructs. further inestigation into the shared heritage of sophisticated terran biotechnology from the end of the 23rd century and our own required. potential for incorporating knowledge into our own crafts and tools.
