Weird Fact of the Day:
Mantas can regenerate tissue after serious attacks or injuries. This is helped by the assistance of cleaner fish, which can aid in preventing infection.
The right image was taken  within a few weeks of a shark attack on the ray, and the left image was taken of the same ray over a year later.

400-year-old Greenland shark is the oldest vertebrate animal
Shark, which would have reached sexual maturity at around 150 years, sets new record for longevity as biologists finally develop method to determine age
By Nicola Davis

Summary of article:

Nielsen et al. (2016) determined the ages of 28 female Greenland sharks using radiocarbon dating of proteins within the inner lens of the Greenland Shark’s eye. The 3 year study found that the oldest shark was 392 years old (give or take 120 years), and that these sharks reach maturity at 156 years (give or take 22 years).

However, it is important to take this discovery with a grain of salt. There are a number of uncertainties that go with these calculations. Clive Trueman (Assoc. Marine Ecology Prof) points out that the proteins in the centre of the eye lenses came from the shark’s mother, which could confound calculations.

Here’s a citation for the study, and a link to where to find it (there’s a paywall).

weals don't eat fish only krill

check👏 your👏 facts👏 before 👏 sending👏 asks 👏 like 👏 this

I already made a post explaining that Rorqual whales (that’s a typical baleen whale with the big throat grooves, like a blue whale or a humpback whale) eat a variety of foods, very much including fish, and with videos to show too, and you can look up the baleen whale wikipedia page if you don’t believe me

New Zealand paleontologists find three ancient baleen whale species
University of Otago paleontology researchers are continuing to rewrite the history of New Zealand’s ancient whales by describing two further genera and three species of fossil baleen whales.

The delicate nature of the jaws and skulls indicate that they were likely not “lunge feeders” like humpback whales, but were adapted for skim feeding— like a slow-cruising vacuum cleaner for krill.
