Recently, colonial algae fossils were identified from Canadian deposits with geometrically connected cells referred to as coenobia from the Cambrian period (~500 MA). Previously, these were thought to be resting cysts of a group called acritarchs. Instead, this colonial form is similar to existing green algae such as Pediastrum.<br><a href="https://royalsocietypublishing.org/doi/10.1098/rspb.2023.1882" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">royalsocietypublishing.org/doi</span><span class="invisible">/10.1098/rspb.2023.1882</span></a><br><a href="https://ecoevo.social/tags/Science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Science</span></a></p>

Well-known, often strange examples include the aardvark and platapus. Zooplankton also have these, some being quite contentious because they are often phenotypically plastic (variable features) but are genetically similar. Bythotrephes longimanus, a Great Lakes invader is one of these.<br><a href="https://www.nature.com/articles/s41598-021-02648-7" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">nature.com/articles/s41598-021</span><span class="invisible">-02648-7</span></a><br><a href="https://ecoevo.social/tags/Science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Science</span></a> <a href="https://ecoevo.social/tags/genetics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>genetics</span></a></p>

As their name suggests, this large plankton (~10 mm) dominate in saline <a href="https://ecoevo.social/tags/lakes" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>lakes</span></a> where there are few fish predators. Their resting cysts are harvested in a lucrative <a href="https://ecoevo.social/tags/Utah" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Utah</span></a> fishery and sold to the <a href="https://ecoevo.social/tags/aquaculture" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>aquaculture</span></a> and <a href="https://ecoevo.social/tags/aquarium" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>aquarium</span></a> industry as live fish food because they hatch out so easily (thus <a href="https://ecoevo.social/tags/SeaMonkeys" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>SeaMonkeys</span></a>).<br><a href="https://www.globalseafood.org/advocate/great-salt-lake-artemia-fishery-becomes-first-u-s-inland-fishery-to-earn-msc-certification/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://www.</span><span class="ellipsis">globalseafood.org/advocate/gre</span><span class="invisible">at-salt-lake-artemia-fishery-becomes-first-u-s-inland-fishery-to-earn-msc-certification/</span></a></p>

The longest animal is a colonial <a href="https://ecoevo.social/tags/Siphonophore" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Siphonophore</span></a>, of genus Apolmeia, which was longer than 120m (400 ft), seen in a deep midwater canyon off western <a href="https://ecoevo.social/tags/Australia" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Australia</span></a>.
