Identification of Crown of Thorns Starfish (COTS) using Convolutional Neural Network (CNN) and attention model. [PDF]

PLoS ONE, 2023
Coral reefs play important roles in the marine ecosystem, from providing shelter to aquatic lives to being a source of income to others. However, they are in danger from outbreaks of species like the Crown of Thorns Starfish (COTS) and the widespread ...

Significant Changes in Bacterial Communities Associated with Pocillopora Corals Ingestion by Crown-of-Thorns Starfish: An Important Factor Affecting the Coral’s Health [PDF]

Microorganisms, 2022
Coral ingestion by crown-of-thorns starfish (COTS) is an important cause of coral reef degradation, although the impacts of COTS feeding on coral-associated microbial communities are not well understood.

Two Hidden mtDNA-Clades of Crown-of-Thorns Starfish in the Pacific Ocean

Frontiers in Marine Science, 2022
Recurring outbreaks of crown-of-thorns starfish (COTS) severely damage healthy corals, especially in the Western Pacific Ocean. To obtain a better understanding of population genetics of COTS and historical colonization across the Pacific Ocean, complete

Capacity for regeneration in crown of thorns starfish, Acanthaster planci [PDF]

Coral Reefs, 2013
[Extract] Population outbreaks of the coral-feeding crown of thorns starfish, Acanthaster planci (Fig. 1a), are, with storms, the most significant disturbance on coral reefs in the western Pacific (e.g., De'ath et al. 2012). Controlling outbreaks of A. planci is therefore increasingly viewed as a key strategy in reducing coral loss and reef degradation.

Protecting Great Barrier Reef resilience through effective management of crown-of-thorns starfish outbreaks. [PDF]

PLoS ONE
Resilience-based management is essential to protect ecosystems in the Anthropocene. Unlike large-scale climate threats to Great Barrier Reef (GBR) corals, outbreaks of coral-eating crown-of-thorns starfish (COTS; Acanthaster cf.

Crown-of-thorns starfish have true image forming vision. [PDF]

Front Zool, 2016
Photoreceptors have evolved numerous times giving organisms the ability to detect light and respond to specific visual stimuli. Studies into the visual abilities of the Asteroidea (Echinodermata) have recently shown that species within this class have a more developed visual sense than previously thought and it has been demonstrated that starfish use ...

Interactive Effects of Endogenous and Exogenous Nutrition on Larval Development for Crown-Of-Thorns Starfish [PDF]

Diversity, 2017
Outbreaks of crown-of-thorns starfish are often attributed to step-changes in larval survivorship following anomalous increases in nutrients and food availability.

Eyes and negative phototaxis in juvenile crown-of-thorns starfish, Acanthaster species complex [PDF]

Biology Open, 2019
As a corallivore, the crown-of-thorns starfish (COTS; Acanthaster species complex), has significant impacts on coral mortality and community structure on tropical reefs throughout its Indo-Pacific range.

Body size and substrate type modulate movement by the western Pacific crown-of-thorns starfish, Acanthaster solaris. [PDF]

PLoS ONE, 2017
The movement capacity of the crown-of-thorns starfishes (Acanthaster spp.) is a primary determinant of both their distribution and impact on coral assemblages.
