scottish-orca:

Using Kandukes weights to length ratio (as West Coasters do eat what would be considered a ‘transient’ diet and I have no other data on weights)The average weight of a male would be : 7,080 kg / 15606 lbThe average weight of a female would be: 6,250 kg / 13778 lb
To put these into perspective, both male and female are heavier than two giraffes (12000 lb) or a A T-Rex at an estimated 10000 lb or Three Rhinos (4600 lb each) or Four Ford Taurus Cars (3,642 lb). !
**it is possible the weight would be much higher as Kanduke died aged 15 and these guys are 30-50+ and scottish bottlenose dolphins are larger than ones in US waters  X **

phocoenidae:

In the 50s/60s, and entirely black Dall’s porpoise was captured off of Japan. What’s really interesting is that the individual was pregnant with an entirely black fetus. Fishermen in Japan have reported occasionally spotting this all-black porpoises.

When this porpoise was caught, other porpoises with normal coloration were in the immediate vicinity. However, the black porpoise did not swim with them and chose to remain off to the side with another all-black porpoise.

(Thanks to ginkotoothed for finding this for me.)


earthstory:

Sutured ammoniteThese extinct relatives of squid grew incrementally, adding new chambers to their shell as the organism within grew, and closing off the used smaller chambers behind them. The empty chambers were useful for buoyancy as they cruised the Mesozoic oceans, saving them energy keeping their altitude in the water column. The species in the photo, Placenticeras meeki is famous for its squiggly sutures between chambers, displayed to perfection in this specimen. It is a late species, coming from the late Cretaceous Hell’s Creek Formation, also famed for its dinosaur finds (most ammonites are found near paleocoasts, it being surmised that the chambers and decomposition gases made them float after death, meaning that most specimens ended up washed up on coasts. The fossil has been replaced with yellow and brown calcite during its slow transformation (along with its entombing surroundings) from sediment into rock, a complex process known as diagenesis. LozImage credit: Heritage Auctions

Striped Dolphin 
The striped dolphin is extremely active at the surface, performing amazing acrobatics including somersaults, back-somersaults, upside down porpoising, and breaching with leaps three times its length.
The striped dolphin body size and shape resembles the short-beaked common dolphin, but the colour pattern is unique; its dorsal side is bluish grey to brownish grey, with a white to pinkish underside.
Striped dolphins are curious animals and will also often bow-ride, sometimes approaching from a distance.
Striped dolphins feed mostly on small fish, such as cod or lanternfish, and small squid. The largest threats to striped dolphins are bycatch in fishing nets, and intentional hunts, particularly in Taiji, Japan.
