Title	Vampire squid reproductive strategy is unique among coleoid cephalopods

Abstract	Coleoid cephalopods are thought to go through only one reproductive cycle in their life. We here report that vampire squid (Vampyroteuthis infernalis) show evidence of multiple reproductive cycles. Female vampire squid spawn their eggs, then return to a resting reproductive state, which is followed by the development of a new batch of eggs. This reproductive cycle is likely to be repeated more than twenty times. This combination of reproductive traits is different from that of any other extant coleoid cephalopod.

Attention Score in Context

This research output has an Altmetric Attention Score of 292. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 09 July 2022.

All research outputs

#105,600

of 23,577,654 outputs

Outputs from Current Biology

#618

of 13,946 outputs

Outputs of similar age

#1,148

of 265,997 outputs

Outputs of similar age from Current Biology

#10

of 195 outputs

Altmetric has tracked 23,577,654 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 99th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.

So far Altmetric has tracked 13,946 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 58.9. This one has done particularly well, scoring higher than 95% of its peers.

Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 265,997 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 99% of its contemporaries.

We're also able to compare this research output to 195 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 94% of its contemporaries.
